Title: Stax: i pirati saccheggiano la nostra cosa

Didn't that magazine cover always make you a little uneasy? I mean, I get the punk swagger, but what sort of lit up disco chick would get into fights while wearing stax sigmas. Or is it that she was punched because she was wearing two transistor radios strapped to hear head with a wire leading down to a brick-sized battery? Or maybe it's some sort of asian fetish to bedeck abused caucasian prostitutes with hifi gear? Googleli would vouch for the latter, so that is why I decided to add a patch to help the unfortunate woman with her periorbital hyphema.

Oh yeah, Stax.

Stax headphones: some people like them, others are degenerate philistines. Let's enlighten those poor unfortunate souls with the grandeur of Stax's cutting edge industrial design and on-the-go practicality.

One of the things that has always bugged me is that when changing from a dynamic to an electrostat your brain takes a second to readjust to what seems like a floaty ethereal presentation. There isn't the same lag as with most dynamics, this is what I think is often referred to as speed. It might be a function of the stat's sharper impulse response or diaphragm resonance characteristics combined with very low harmonic distortion and a relatively large radiating area.

What I've noticed is that with stats with increasingly thicker diaphragms, (>1.5 microns, sometimes approaching ortho girth) the efficiency drops and the sound takes on a more tangible depth, the bass notes linger maybe a bit longer and seem to hit harder. Of course the trend has been to switch to advanced materials and reaally thin diaphragms (.5 micron) and switching to higher voltages and greater radiating area.

This is a thread meant to collect listener experiences with specific stat models and a bit of bullshitting about theory and application. I'd definitely like to learn more than the embarrassingly small amount of knowledge I possess regarding the engineering of stats and stat amps. This of course is balanced by the embarrassingly large amount of knowledge about specific models I've scraped from head-fi-case and wikiphonia. Maybe next time I'm at a meet I'll be able to play the expert and give a precise answer to a listener's technical question about the 007's impedance ("um, it changes with frequency I think? yes there's impedance").

Welph, my experience with them Staxes has been limited to some few Lambdas (407 & 20x where x = something), and the venerable 007s and 009s. Did not have any of these for months and years though, so that's that. I thought they sounded sort of U-shaped in general, but w/o the expected bass impact or Beyer-brightness if that make sense. Perhaps that's what "ethereal" sound is all about.This I felt on all of the ones I heard, with some differences here and there in the presentation depending on the model.

The ESP950 was a significant departure from the Staxes IMO tho. Did not feel the pseudo U-shape or ethereal whatever response. On the other hand, going by memory, it sounded fairly laid back. More so than the Staxes. Maybe at some point I'll give them another listen to form a better opinion on them. I do like laid back sound sometimes.

... and yes. The unique Sigma... YMMV, but IMO they SUCK!

SR009 + Cavalli LL is the only Stax experience that made me envy. Everything else I've tried has kinda been meh for me. The lack of impact might be the thing that bothers me most, but I don't have the most electrostat experience compared to fellow pirates.

I perceived the "differences" (not spelling out superiority here) of electrostatics vs. dynamics to be more dramatic than that experienced when upgrading from mid-tier to high-end headphones. My first electrostatic was the HE60 and I consider it to be more of a turning point within my journey than even my first CIEMs (OG JH13s).

I would be very interested to better understand what causes many electrostatics (e.g. Lambdas, Omegas) to sound broadly different from other transducer types at a fundamental level.

The most annoying thing for me has been understanding the amplification behavior of electrostatics, since we need to think differently from the resistive loads we're used to talking about.

Although I've owned the 007 O2mk1 for many years prior it wasn't really until this year that I really came to appreciate the Stax sound.  I do agree, the ESP950 while an excellent headphone doesn't convey the same house sound as Stax.  Once I got bit by the bug I found it very difficult to switch back to dynamics!

For anyone looking to get started I learned the hard way that the tubed Stax brand amps really are just hybrid designs that compromise in the wrong ways namely is that they are underpowered especially for the more demanding stats, you'll be in a much better starting position to aim for a solid state amp.  Not to say they are horrible or anything but they may not be as versatile when you start experimenting.

The ugly lambda frames are also quite fun sounding if you can get over the look, plastic build, and have the right shaped head.  Like Grado the lower end lambdas are a much better overall value than the more expensive ones - not uncommon that you will find differences in pads and cable rather than differences in drivers.  I came into an old beat up Lambda Nova Signature which really floored me overall.  Although I enjoyed the 407, based on what I have read I don't think any of the modern sets will sound close unfortunately!

Up the ladder I know that one nice thing about the 009 is that they are much easier to amp than the 007's so if you look at it one way the high cost of the 009 can be supplanted by lower cost amps if you are on a limited budget or have a upgrade plan in place.  I still don't know if I would recommend to someone to start at the top though!

The lack of impact might be the thing that bothers me most, but I don't have the most electrostat experience compared to fellow pirates.

I felt the same way, first stax I heard were the o2mk1s on a BHSE at canjam 2010 and the lack of impact was a massive deal breaker for me. For too polite/soft I would say. But then several years later I got to hear the 009s for the first time and it was literally love at first listen. And that was on the A-10, which is supposed to be a pretty atrocious Stax amp

I feel you Mr. Sneis, been trying the HD800s in house for quite a while now, and even if there might be a small part of my brain that will admit they might be better at some things, I just don't love them like I do the 009s...that and I don't find them to be nearly as comfortable long term

that's always been my thing against the newer Stax.  Lack of bass impact and punch with ethereal notes that don't sound like any music I've ever heard from a musical instrument. I notice the same thing from Saunders, Magnepan and Martin Logan to various degrees but it's always there when I hear it.  I considerate an unnatural coloration that I've been known to call a 'gimmick' from time to time.

Bottom line, if you have to rely on psychoacoustic adjustment to get your brain to adapt to a particular house sound, that sound is just wrong.  It either sounds like a natural instrument or it doesn't.  I have always felt the older Stax and Senns sound more correct than the newer stuff often held up like God's gift to the non hearing impaired.  Ultimately no planar has given  myself that 'there' feeling by stripping every bit of information from a recording and rendering it back as much as  a proper HD800 rig has so far.  If the HD800 were the statue of David, some of the more recent Stax are like a Japanese watercolor painting of David on rice paper.

I think veil on some dynamics and that ethereal sound on many stats are the most off putting things I notice when I try out headphones for the first time. Instant deal breaker for me.

Regarding the Lambda line: There have been small changes to the stators from gen to gen but they're pretty much identical within the same generation.  In the original Lambda trio, the big differences were thickness of the diaphragm and, obviously, change in bias.  There is a noticeable difference in sound just by changing diaphragm thickness.  Most of the later trios kept the same diaphragms between them but used different pads/cables from one another.  I have a feeling they also either change the tension slightly between models from the same era, or they are pickier about channel matching between drivers.  Former can be measured with a FR plot of the driver alone in open air.

I'm pretty much dedicated to stats as well.  Dynamics all have a grain to them (varying degrees of course) that I find distracting, and that can't be helped with mods or EQ.  My dynamics have either been sold or in their boxes for years.  Downside to Stax is less room to play if you're a tweako, which can be a positive or negative thing depending on your perspective.

I like the Sigma a lot but think there is much room for improvement, especially with better pads.

Post by: Mr.Sneis on May 21, 2014, 06:14:09 AM
I know n3rd that you know this already but for the uninitiated a relatively easy and affordable "tweak" is to swap pads across Lambda models as they are all the same overall shape and affixed with double sided adhesive.  I don't think it's discussed too often but I'm with the camp that believes the older thicker pads sound better than the modern pads -- greater distance between ear and speaker.  I first did this with a 407 and somewhat appreciated and regretted the change at the same time.  With the LNS I have now I'm afraid to mess with the older pads and accompanying ear-side foam too much in fear of harming them.

Copied from a PM:
After talking with a few people around head-fi (one of whom is in a nearby city, who owns 5 STAX headphones and a few different STAX tube amps), I took the plunge on the SR-202s and bought them for ~$300 from Yahoo Auctions on Japan. I had a friend who was in Japan buy some of the real leather pads from the SR-507 to put on my 202s, and I've been completely satisfied with them ever since. Out of all the lambdas that I've heard so far (Airbow modded 507, 404, 207, Lambda Nova Signature and Lambda Signature) the 202 with the 507 pads has been my favorite so far, because they've been the least bright out of the bunch. I think it was the LNS that was the other not very bright one, but the midrange was too harsh for my liking.

Regarding the Sigma, I got the chance to hear the Sigma SB at the above mentioned person's house, and I quite liked its soft yet (relatively) detailed treble, and the bass wasn't actually all that annoying.
Did they just strap some lambda drivers in a different enclosure and put some damping around your ear though?

I really feel it's tough to describe the electrostatic sound. On one hand, I feel that the bass doesn't extend as far as I'd like, and the midrange isn't quite balanced, and the treble can either sound too harsh or too rolled off depending on my mood, but on the other there's a certain effortlessness and openness that the STAX exhibit that very few headphones of other driver types exhibit, which is why I feel I love my STAX so much.

While I feel the Lambdas I heard had indeed the ethereal presentation, I did not dislike them at all. I also feel that while the Lambdas are fugly as hell (proly more than the Abyss), the SRS-2170 ear-toast combo seems decent if the Lambdas signature jives well with what one is looking for.

That said, I like my uninitiated HD600s bettar so far. I don't think the HD600 does low bass like a boss, but it's decent IMO. The rest of the spectrum and the detail I get w/o pain is something I welcome. I also like the openness these cans provide when the recording demands it.

The practicality and options available in general for dynamic cans is also a consideration, not to mention than for as little as $15 one can get half decent sound from dynamics (KSC-75). Would be hard IMO to see that kind of value in stats.

I can totally understand this, I just don't like the notion this is somehow uber transparent, the last word in detail, the pinnacle of sound, or 'superior' to other alternatives.  The most 'stat' ethereal sounding rig I've heard is a Sanders speaker rig which sounds absolutely unnatural but utterly seductive, engaging and intriguing to me.  Very precise 3D images that are somehow hollow.  Listening to it is as if Monet is painting musical soundscapes in the air around me.  If I had the money and room I'd pick up a set.  However, I wouldn't run around telling everyone who doesn't have Sanders speakers that their speakers are sh1t or technically 'wrong' like some Stax fascists do.  The problem is I don't find real instruments to be effortless.  They have weight, pluck, bang, snap, sibilance, shrieking, all sorts of stuff that seems to get lost a bit. To me, real music has a force and presence behind it. I once heard a Stax fan call that sort of sound dynamic driver "compression" lol.

Heh, just realized I was writing some notes down with an Edifier pen before posting this.  Does that make me a Stax fanboy?  :P

Yes, pretty much.  The normal bias Sigma uses normal bias SR-Lambda drivers and the Sigma Pro uses SR-Lambda Signature drivers.

Hmm, sorry if my writeup came off as making it sound like 'stats were the end-all things, because I don't think they are either. They sound a little bit ethereal to me as well, but compared to the Sony MDR-SA5000, pretty much the only headphone I've heard that has a bit of the same "effortlessness" in the treble if you will, sounds much more ethereal to me than the stats, by a long shot. I don't wanna derail the thread and take it into a debate about that headphone though, so I'll shut up.
I get what you mean though. I get the feeling there's a certain "organic-ness" missing from the 'stats that's very present in something like the HD650.


Did they just strap some lambda drivers in a different enclosure and put some damping around your ear though?
Yes, pretty much.  The normal bias Sigma uses normal bias SR-Lambda drivers and the Sigma Pro uses SR-Lambda Signature drivers.
Hmm, seems like you could 3D print some cups for a pair of lambda drivers to make a clone of the Sigma for significantly less than the actual price of a sigma then... (writes down that idea for when I get a spare pair of lambda drivers)

Just wanted to add one more criticism to the Lambdas, and that is it seems like even though my 202s are the darkest lambdas I've heard, there can still be a bit of harshness on poorly recorded electronic tracks and whatnot. I think that out of all the headphones I own (and quite a few that I've tried) I prefer the lambdas for piano recordings and a lot of the Japanese video game OSTs I listen to. They sound a bit too ethereal for rock tracks, but I still enjoy them there nonetheless... (shrug)

If you're serious about 3D printing Sigma cups, I think jaycalgary listed the measurements he took of his set when he made his own Sigma cups.  There's a thread on HF somewhere. 

As for not highlighting poor recordings, you'll probably have to find a headphone with some recession in the lower treble.  The SR-007 and Sigma come to mind as Stax headphones that are more forgiving of poorly mastered records.

Had a little of exp with 2 SR-009 rigs, 1 with a Cary Signature and the Woo tranny and another with the Woo amp. I really love the lower mids of the electric guitar in various rock/metal music and the weight that comes with the HD800 just can't be found on the 009 rigs I tried. Same experience with Anax really. I would love to get an 4170 system, pretty much a dream for me at this point of time. I do see the appeal with Staxen though but its just not for me.

I feel the same way. I've always wondered if this would be objectively confirmable or if it's an ostensibly irreversible bias ingrained within my pysche.

I'm not sure if my opinion of the SR-Omega being the most revealing transducer I've encountered is due to that actually being the case or due to its ability to resolve without any grain, etch, or other treble undesirables. I hope it's the former as I readily identified the HE60 as a notch below the HD 800 in resolving capability (although the HE60 "sounded" faster and cleaner).

I also thought my HE60s and SR-307s had aight bass that lacked impact and extension, but I feel that my Omegas have super-duper bass all around. The Omega do have the largest transducer of any Stax ever made IIRC (~90mm diameter) so maybe that counts for something. I haven't compared them closely enough against the SR-009 though.

Whoa, someone has seriously already done it? :o
I'm serious, but it will probably be a while before I invest in a pair of lambda drivers to mess around with.

I heard the 007Mk1 recently at the Seattle meet, but on the Cavalli Liquid Lightning (which also had a 009 connected to it), and the owner told me he had some very warm sounding tubes to try and "warm up" that 009, so I felt the 007 was a bit too warm sounding. Guess I should have asked him to let me try it with my solid state 212 amp instead. :D

There was another 009 at the meet as well, being driven by a KGSSHV and some expensive looking Oppo DAC, but I think pretty much everyone who heard it (including me) came away unimpressed. The KGSSHV sounded really warm, but not warm in a good way, warm as in the top end sounded rolled off and the whole experience was just "meh"; I honestly felt my 202/212 sounded just about as good versus the KGSSHV/009 combo, that's how bad it sounded. Can anyone else verify this, or could it have been something else that was wrong with the system, like an improperly built KGSSHV or something?

Oops, I didn't clarify...he didn't 3D print his sigma cups, he made them from chicken wire and some other stuff I think.

N, I agree with much of what you have to say.  I also find the SR-Omega (and a number of other stats) more resolving than the HD800, which I consider possibly the most resolving dynamic. The HE60 is one of the few stats that doesn't sound all that resolving for some reason, along with the ESP950.

LOL, I think I understand what you talking about in reference to the SA-5000. Not the best quality treble, not as fast or smooth, but the effortless presentation is similar to STAX.

Had a little of exp with 2 SR-009 rigs, 1 with a Cary Signature and the Woo tranny and another with the Woo amp. I really love the lower mids of the electric guitar in various rock/metal music and the weight that comes with the HD800 just can't be found on the 009 rigs I tried.

Yes, there's a certain weight or tactile feel the HD800 has that the STAX do not have. Not necessarily talking about bass impact, but rather tactility throughout the mids and the highs. This "etherealness" nonsense seems to be an issue which plagues STAX and not some of the other electrostatic headphones. The Orpheus and Jade had a certain tactile feel in from the mids on up which the STAX also did not possess.

BTW, I also felt the Orpheus and Jade were more resolving, better at extracting microdetail and especially better at microdynamic rendering, with the 009 sort of blacking out of dropping low level information. (Anax and I also directly compared BA/HD800 and T2DIY/009 - tonality, bass impact differences, overall presentation differences aside, the HD800 rig was better at microdetail extraction and microdynamic rendering, the 009 rig was less veiled and faster.) The 009 is still king of clarity.

I remain curious what a well designed DHT SET amp (instead of the push-pull or DIY commercial hybrid/SS offerings) for electrostatic headphones could do. This is probably the only way to level the playing field. I still remember Frank Cooter's SET amp with the blue mercury PS tubes. Even though Frank was running SR507 (screwy FR), it was by far the most "involving" stat rig I had ever heard on the same league of n3rdling's Orpheus.

In the end, I felt the electrostatic stuff was too niche, too screwball of a technology, too limited with good amp choices, too vintage (Senn Orpheus), too craptastic customer service (STAX) for me to stick with. If Senn had brought back the Orpheus, it would have been a different story for me.

Not at all, just citing some general comments u find on the interwebs.

Agreed about the HE60.  The Omegas are some of my favorite Stax and possibly some of the best mids in headphonedom. However I always feel the treble and bass lacking for my tastes.  Not enough splash or sizzle, or bass punch and impact when called for.  Despite the lovely mids, it sounds kind of laid back to me keeping me from rocking out.

I heard the 007Mk1 recently at the Seattle meet, but on the Cavalli Liquid Lightning (which also had a 009 connected to it), and the owner told me he had some very warm sounding tubes to try and "warm up" that 009, so I felt the 007 was a bit too warm sounding.

Can anyone else verify this, or could it have been something else that was wrong with the system, like an improperly built KGSSHV or something?

I think I can.  I feel pretty much the same way about the KGSSHV.  Warm and meh sounding but better warm and meh than a 323 but very similar.  Oppo is overrated in everything, headphones, transports, even bluray players. They were good back in the day when they were a feature set based bargain choice, but now they like to play in rarified audio/videophile air.  Most decent DACs/transports are better than high end Oppos and both my my LG bluray drive on my PC and a $100 Pioneer Elite Bluray player I got from a swap meet rocked the Oppo 105 when I did a side by side. Don't believe the hype.

Liquid Lightning is a tube amp??

I remain curious what a well designed DHT SET amp (instead of the push-pull or DIY commercial hybrid/SS offerings) for electrostatic headphones could do. This is probably the only way to level the playing field. I still remember Frank Cooter's SET amp with the blue mercury PS tubes.

Well we know who has had a DHT SET Estat amp circuit ready for assembly for the last few years, unfortunately he feels content to market the push-pull design of someone else due to the small volumes Stats represent, and the rather over zealous nature of a certain group of fanboys who like to smear competition they can't hang with using they amateur hobbyist DIY designs.

Despite the FR, the 507 is certainly an involving stat, that's for sure.

I find these impressions pretty interesting. The KGSSHV I heard had excellent treble extension but surprisingly strident upper harmonics (e.g. violins could be a little painful to listen to), though it was fine with the SR-007Mk1. Generally speaking when some Stax enthusiasts speak of moving up the amplification ladder (top being the DIY-T2 then BHSE just below), they're gunning for better performance and extension in the extremes and very few belabor perceived benefits in the midrange. Maybe that's due to stats representing a capacitive load but I'm no expert on this.

With the DIY nature of the KGSSHV, I am a little curious if individual liberties in design from build-to-build (even beyond output stage) translate to different final performance outcomes. It would certainly do no favors for comparability if some of us were talking about McIntosh KGSSHVs and others Granny Smith KGSSHVs (or maybe some apple type everyone here hates).
In the end, I felt the electrostatic stuff was too niche, too screwball of a technology, too limited with good amp choices, too vintage (Senn Orpheus), too craptastic customer service (STAX) for me to stick with.
Eh, I would be inclined to agree. Then there's some esoteric BS like parasitic charges and phantom imbalances that nobody else has to deal with which plague the broad range of electrostatic models. Just reading that SR-009 imbalance thread makes me mad -- those kind of issues have no place in a $3500+ product whose sheer purpose can be defeated by fate and chance.
Well we know who has had a DHT SET Estat amp circuit ready for assembly for the last few years, unfortunately he feels content to market the push-pull design of someone else due to the small volumes Stats represent, and the rather over zealous nature of a certain group of fanboys who like to smear competition they can't hang with using they amateur hobbyist DIY designs.
The politics in the Stax market are absolutely confounding and will inhibit them from being any real threat to dynamic transducer types (besides the other reasons mentioned as well) for the vast majority of people. Of course this might not matter as Stax doesn't seem to be concerned about expanding their market size.

It's a shame that the small size and cult-ish status of the Stax market lead a considerable proportion of outsiders to regard them as some sort of "holy grail." Instead of championing superiority without familiarity (e.g. "hey everyone says the SR-009 is amazing and it costs $3500 so Stax must be the best"), they could just spend a cool ~$500 to grab the SRS-2170 or a used Lambda setup. There are indeed limitations as touched upon in this thread though I would consider a Lambda at least to be as "essential an experience" as the HD 600, HD 800, HE-6, LCD-2, et al.

From the little I know about KGSSXX builds, there might be all sorts of board revisions, builders, and part differences between them. As a DIY product, I guess that's sort of understandable. As a commercial kilobuck "holy grail" product, that's a bit problematic. (For me DIY is not the same as commissioning someone(s) to build stuff, mainly because I-did-not-do-it-myself. That's fairly commercial custom work IMO.)

This may be wrong, or it may be obvious or not, but I think the main difficulty that stats face, in general, to gain on dynamic transducers market share are their relatively large voltage requirements.

are their relatively large voltage requirements.

Yup, screwy technology. That's why they will always be niche. It's worse than diesel, more like powering a car with a turbine engine.

I do wonder if N and ZD's impression of the KGSS rig being strident had at to do at least partially with the source? Was it an Oppo SACD player? I know some of the Oppos can be lean sounding. I also know they both compared that KGSS setup to Alex's Liquid Silk with that R2R DAC - what was that DAC again?

Hmm, sorry if my writeup came off as making it sound like 'stats were the end-all things, because I don't think they are either.

Not at all, just citing some general comments u find on the interwebs.

Dynamics all have a grain to them (varying degrees of course) that I find distracting, and that can't be helped with mods or EQ.

I feel the same way. I've always wondered if this would be objectively confirmable or if it's an ostensibly irreversible bias ingrained within my pysche.

I'm not sure if my opinion of the SR-Omega being the most revealing transducer I've encountered is due to that actually being the case or due to its ability to resolve without any grain, etch, or other treble undesirables. I hope it's the former as I readily identified the HE60 as a notch below the HD 800 in resolving capability (although the HE60 "sounded" faster and cleaner).

Agreed about the HE60.  The Omegas are some of my favorite Stax and possibly some of the best mids in headphonedom. However I always feel the treble and bass lacking for my tastes.  Not enough splash or sizzle, or bass punch and impact when called for.  Despite the lovely mids, it sounds kind of laid back to me keeping me from rocking out.

I heard the 007Mk1 recently at the Seattle meet, but on the Cavalli Liquid Lightning (which also had a 009 connected to it), and the owner told me he had some very warm sounding tubes to try and "warm up" that 009, so I felt the 007 was a bit too warm sounding. Guess I should have asked him to let me try it with my solid state 212 amp instead. :D

There was another 009 at the meet as well, being driven by a KGSSHV and some expensive looking Oppo DAC, but I think pretty much everyone who heard it (including me) came away unimpressed. The KGSSHV sounded really warm, but not warm in a good way, warm as in the top end sounded rolled off and the whole experience was just "meh"; I honestly felt my 202/212 sounded just about as good versus the KGSSHV/009 combo, that's how bad it sounded. Can anyone else verify this, or could it have been something else that was wrong with the system, like an improperly built KGSSHV or something?

I think I can.  I feel pretty much the same way about the KGSSHV.  Warm and meh sounding but better warm and meh than a 323 but very similar.  Oppo is overrated in everything, headphones, transports, even bluray players. They were good back in the day when they were a feature set based bargain choice, but now they like to play in rarified audio/videophile air.  Most decent DACs/transports are better than high end Oppos and both my my LG bluray drive on my PC and a $100 Pioneer Elite Bluray player I got from a swap meet rocked the Oppo 105 when I did a side by side. Don't believe the hype.

Liquid Lightning is a tube amp??

I remain curious what a well designed DHT SET amp (instead of the push-pull or DIY commercial hybrid/SS offerings) for electrostatic headphones could do. This is probably the only way to level the playing field. I still remember Frank Cooter's SET amp with the blue mercury PS tubes. Even though Frank was running SR507 (screwy FR), it was by far the most "involving" stat rig I had ever heard on the same league of n3rdling's Orpheus.

Well we know who has had a DHT SET Estat amp circuit ready for assembly for the last few years, unfortunately he feels content to market the push-pull design of someone else due to the small volumes Stats represent, and the rather over zealous nature of a certain group of fanboys who like to smear competition they can't hang with using they amateur hobbyist DIY designs.

Despite the FR, the 507 is certainly an involving stat, that's for sure.


Ya, the Omega has pretty sublime mids.  Goosebump-inducing.  It has quite a midbass kick, but any lower and there's not much impact.  Great with live rock recordings especially.

Since it's being brought up, can we just ignore the KG/Alex/spritzer/HC/sachu/etc shit for once?  It would be refreshing to talk about electrostats on changstar without that stuff coming up every single time.  As it is I pretty much can only talk about that stuff in PM here because I know somebody will inevitably get that argument going.  Maybe I'm alone in that thinking, but the relative lack of 'stat talk on CS makes me think others quietly feel the same way.

I agree that stats will always be a niche within a niche, and really only because of the high voltage requirements.  The only way for this to change would be if Beats or somebody wanted to up the ante and release a volume compromised (read: very low voltage swing amp packaged with the headphones) HP system.

I think DG can agree with you on that one.

TBH I've had a pretty intense but rewarding Stax journey these past few months and am happy with where I've gotten aside from losing a couple hundred bucks in stuff I didn't end up liking/keeping.  The hard part is because there's much less hype and fangirls around some of this gear that it's not as easy to get into and out of gear unless you are willing to learn the hard way.  "Team Gilmore Girls" I would say has sound advice if you read between the lines; and I'm in all earnest trying to say that as a neutral party.

The existing info out there is a bit disorganized but it's there if you look *really* hard and have the time to boot.

Oops, I didn't clarify...he didn't 3D print his sigma cups, he made them from chicken wire and some other stuff I think.
Hmm, okay. I'm wondering if some 3D printed cups wouldn't actually be better than the material STAX used for the sigma!  :)p3

Hmm, sorry if my writeup came off as making it sound like 'stats were the end-all things, because I don't think they are either. They sound a little bit ethereal to me as well, but compared to the Sony MDR-SA5000, pretty much the only headphone I've heard that has a bit of the same "effortlessness" in the treble if you will, sounds much more ethereal to me than the stats, by a long shot.
LOL, I think I understand what you talking about in reference to the SA-5000. Not the best quality treble, not as fast or smooth, but the effortless presentation is similar to STAX.
Yeah, the treble isn't grain-free or smooth like the STAX, but it does have the effortlessness. Strangely enough, any songs without any vocals, or those with artificial voices (vocaloid) don't sound half bad, but vocals sound way too fake.

Alright, just wanted to make sure. :)

Huh, I'd never really thought much about Oppo other than that they were expensive. Maybe the combination of the Oppo and the KGSSHV made that 009 sound especially bad....

My bad, I meant the Eddie Current Electra. I knew it was one of those expensive 'stat amps. :p

The KGSSHV sounded really warm, but not warm in a good way, warm as in the top end sounded rolled off [ . . . ] Can anyone else verify this, or could it have been something else that was wrong with the system, like an improperly built KGSSHV or something?
I find these impressions pretty interesting. The KGSSHV I heard had excellent treble extension but surprisingly strident upper harmonics (e.g. violins could be a little painful to listen to), though it was fine with the SR-007Mk1. Generally speaking when some Stax enthusiasts speak of moving up the amplification ladder (top being the DIY-T2 then BHSE just below), they're gunning for better performance and extension in the extremes and very few belabor perceived benefits in the midrange. Maybe that's due to stats representing a capacitive load but I'm no expert on this.

With the DIY nature of the KGSSHV, I am a little curious if individual liberties in design from build-to-build (even beyond output stage) translate to different final performance outcomes. It would certainly do no favors for comparability if some of us were talking about McIntosh KGSSHVs and others Granny Smith KGSSHVs (or maybe some apple type everyone here hates).
Hmm, I noticed a bit of harshness as well, but I'm not totally sure if it's the 009, KGSSHV, or the Oppo player. How much do KGSSHVs usually cost anyway? I think he said he spent ~$2000 on it and it looked like there was a pretty good case, so could it be possible some compromises were made inside? I thought they cost a little bit more than that...

Also on another note, I also heard the Airbow modded SR-507, and I'm not sure how it compared to the SR-507 unmodded, but honestly I didn't think it was very different than the 207 that I heard...

I think the relative lack of stats on this forum has more to do with your second point than anything else one might read into it.  It all seems relatively proportional to the market share of dynamics, orthos and stats to me.  Not to mention the sonic characteristics that some of us mentioned having issues with, so some went through the Stax phase and ended up leaving.

Since you brought up names, I can guarantee you won't get improved market share and product proliferation when one rabid group continues to slander competitors that aren't made by Justin or designed by fake 'Doctor' Gilmore, who apparently inspired all of Stax's amp designs, lol. It would also be refreshing for once to not see people parroting uncorrected lies, slander and hypocritical comments  from some of those you mentioned who feel the need to mark their territory like dogs peeing on a tree because of petty ego problems.  Don't ya think? I never said anything about Sachu and Alex so that's you bringing that up, not me.  But I'm happy to leave it lay for sure.

My original point was about a DHT SET amp and that there are some very well know amp designers that have expressly stated they will never go to the trouble of making a stat amp largely because of said group and their disproportional influence over such a small segment of the market.  IMHO, such environment does nothing to benefit the proliferation of stats if that's the concern.

I really don't think high voltage is too much of a problem.  Yeah, you can't plug in a 009 to your iPhone but consider that every desktop amp in every house around the world could have been a stat amp for a stat phone if people wanted it to be.  In those cases, someone choosing to put a box on their desk to listen to headphones is not worried about high voltage as an impediment.  So I think it's a bit more complex than that like poor marketing, poor support, cost and other issues.

Admittedly I've never heard the KGSSHV but I've heard the HV can exaggerate the brightness a little bit more than the standard KGSS of certain phones - take the 009 for example.  If this is specific to the HV or maybe it's down to source or rest of the chain I can't know for certain.

Prices for standard KGSS have been creeping down towards $1800 based on recent experiences - in fact I think there's one on HF listed for that much right now.  This could be thanks to the popularity of the HV which seems to command a premium upwards of $3000 based on some recent listings.  I know some have snagged HV's for much less but for mere mortals such as myself seems to be a challenge.

Hmm, okay. I'm wondering if some 3D printed cups wouldn't actually be better than the material STAX used for the sigma!  :)p3

3D printed plastic is usually pretty garbage so in terms of materials I really doubt it.  The advantage would be the ability to alter/improve the cups by changing the dimensions easily.  Again, I think there's lots of room for improvement here.

I think the closer the drivers are to the ears, the better the low end extension and presence based on what I heard and seen.

The shape of the pads are all the same (internal oval/external rectangle).  There are differences in pad material, thickness, and some have the bottom corners puffed up a bit.

Sorry, I wasn't specific when I said 'relative' but I was referring to talk of stats here relative to HF/HC, not in terms of sales.

I only put Alex/sachu in there because they end up getting thrown in the mix eventually as well.

Speaking of DHT stat amps, I think Frank Cooter is working on a new one for the next meet IIRC.  I think my fav design of his was at CJ 2010...I remember being hooked to his system driving the SR-007.

Just needing an amp already limits the market significantly though.  Portability is a huge deal for headphones.  I'm pretty sure this is why Oppo seemed so focused on making the PM-1 super efficient, possibly at the expense of some tradeoffs.  Now you can have a swanky planar magnetic in your carry on and drive it directly from your phone.

Leaving Alex and Craig out out of it...

There have been several manufacturers who have voiced concerns to me regarding the mafia defamation against "outsiders". The decision to make an electrostatic amp based on engineering difficulties is already one tough engineering hurdle. The potential STAX mafia BS they perceive they have to deal with pretty much makes the decision not to bother rather easy.

Ultimately, I don't give a sh1t because I went down the STAX road and decided it wasn't for me. Even now, I'm still more into speakers and will probably build a vintage Altec horn system next. I may go back to STAX, but honestly, I'd rather apply those funds to a Porsche Cayman, since as I age, my eyesight is turning to sh1t and reactions are slowing down. I have no plans to be like the middle aged fat slob type driving a Corvette in the left lane at 53mph. (Gawd, I hate those fuckers.)

Finally, I understand why these conversations may involve the STAX mafia as they really were the pioneers and we have to acknowledge the contributions they have made.

However I have never understood WHY THE fvck SACHU ALWAYS GETS RANDOMLY DRAGGED INTO IT. I mean WTF does Sachu have to do with STAX other than once owning an 007mk1? I mean Sachu wasn't even part of the LL debacle on HC. Yes, Sachu did get his ass bounced from HC like half a decade ago; but again, what does this have to do with STAX? I mean gawd fucking damn it.

BTW, the reasons there isn't much STAX talk here compared to HF:
Finally, the STAX talk on HF is mostly a rehash of the same old crap most of us already know or just don't care about. You dont see us talking about TH900, RS-1, Abyss, HE-6 all that much anymore.

But you never know. We didn't talk about DACs much until Anathallo started the "Not a lot of DAC talk thread in here". Now that DAC thread is the largest on this site. So maybe, just maybe 'tode had something in mind when he started this thread.

I think the mafia has done damage to the commercial appeal of e-stats.  If you believe the forums then the only option for high end performance is the BHSE, which means waiting 1+ years for Justin to fill your order.  It certainly can't help with sales if the recommended amplifier is not easily accessible.

I agree with Marv about the 009 being the clarity king.  From the 717 it was really something to behold in that regard and it still sticks with me as the ultimate reference.  I couldn't get over the lack of microdynamics and soundstage though.  I could be very happy with that combination in a relaxed non-critical listening way.  It lacked that musical engagement or realism that I ultimately desire.  I am not sure the KGSS/KGSSHV could improve on those things enough over the 717 to make it a worthwhile investment over going to the BHSE/LL/Electra.

Great thread, especially for me since I am certainly a Stax fan. There's something about them that I just fell in love with when I first heard them.


The only "high end" headphones I had for the last 15 years was the Ety ER-4S.


Then a couple years ago, I bought a Smyth Realiser so they said I need to get Stax to go with it. Without ever hearing Stax, I bought a used pair of 407's and a 323A amp from Japan. When I finally received them, I could not believe how good they sounded bearing in mind that I had never heard any high end headphones before.


But somehow, even after listening to many more headphones since then, I always seem to come back to the SR-009's. I just love the Stax sound, good or bad. I own HD800's, ESP-950's, Noble K10, N6 and soon Enigma's and Paradox Slants. I have also spent a lot of time with the LCD-3's and LCD-X's. But I find myself comparing everything to the 009's as my reference. Only now am I realizing that the SR-009's are not without problems, but I still like them the best.


With regard to other amps, hopefully the Vostok Sound electrostatic amps will find a few buyers once the final version is available. Based on all the "Stax Mafia" comments, maybe it's foolish to try to build, market, and sell a new electrostatic amp. We'll see what happens. But realizing that building an electrostatic amp is a very niche product, I strongly suggested to them that they include a high end dynamic headphone amp too. At least this way they may stand a chance of surviving. I guess "the proof is in the pudding" hoping that the Vostok Sound products are any good. I think they are, but I'll leave that up to the experts here.

Lol, I had actually entertained the idea of a synergized 009 rig for backup non critical listening.  But seeing how little time my HE5, HP1, ESP950, SRXs and SA5000 get, probably not the wisest decision to make.  Maybe someday unless Sennheiser or Fang do something special.

I'm sure there will be more Stax/Stat talk here once their new flagship amp comes out and/or other phones too.  Supposedly the latest Kingsound iteration is possibly decent sounding.  I'll find out next Friday.

I know ship is a big 009 fan but he may have had to abandon it while working on the road.  I think Tari still has/likes the 007 but uses the HP1 the most.  Romy might have a couple dozen Stax buried in a closet somewhere?

I really dig the 009 but it's not my favorite stat.  IMHO, it's a great headphone, but Like EVERY headphone I've ever heard, it's got it's problems.  And I'm OK with that.

Here is, more or less, where I am on the headphone journey...

I made the move seriously towards stats about a year and a half ago, hell it might have been a little longer.  I had made a run through quite a few dynamics and orthodynamics before that.  I was ready for a change.  I sold most of my dynamics.  At the time it was also about simplifying things, but it went horribly wrong!  I ended up building up a much larger collection of stats (headphones and amps) than I had previously had with dynamics.  I like music a lot, but I'd be lying if I didn't admit to liking gear as well.  It's part of this hobby for me.  So the stat collection was as much about learning about what each different model sounds like as it was just plain fun for me.  I don't want to put up a big gear list, but lets say that I currently own a fair collection of pro-bias stats (and amps).  The only real exception is the HE-90 which I've only heard, never owned. 

That's a rather long winded way of saying that I make my own impressions of this stuff by extensively listening to the gear I own.

Today my two favorites are the original Omega and the "impossible" Jade.  The former is a wonderful, but also slightly flawed headphone. It's becoming as rare of hens teeth with original drivers, so I have to admit I always worry a little when I handle and listen to them; which I do regularly because headphones are for listening!!  For the money they are not going to get replaced if anything ever happens to them. 

The later shouldn't sound as good as it does, it's "impossible"; by all reports most samples are horrible!  But this slightly modified Jade has some sort of crazy ju ju (Chalk it up to a happy mistake driven crap QA/QC) that makes it wonderful to listen to.  Check out the measurements here on Changstar.  The build quality is so poor that I'm convinced they are just going to fall apart in my hands some day, but in the mean time I love 'em. 

Also high on my list are the Jecklin Floats.  Romy and I don't talk about them much publicly as we're sure to be put in straight jackets and locked up for heresy, but they are damned good! 

I expect the 007 to get re-evaluated later this summer when the BHSE arrives.  That said, I always wonder why it's so maligned... it's a another damned good headphone.

I listen to a variety of stats at work daily, from Lambdas to Sigmas, from 4070's to in-ears, ESP-950's and modified King Sounds. 

When I travel I almost always take the 002's with me for use in the hotel and remote offices but for actual travel I use UE (UERM and UE11) customs and a variety of amps, DACs, and players.

So yeah, I'm pretty much into stats now days.

I've slowly bought back a few dynamics.  I don't plan to gather (m)any more. For now the HD-800, LCD-3, AKG-K-1000, Paradox, and Slant are more than enough.  There are many reasons I like having these headphones around, but one major reason is so that I have dynamics for headphone amps I am building and want to build.

I have a plan to thin things out and explore some speakers when I return the USA, but who knows?  I am happy I went down this road.  It's been fun and I think I've got great sounding gear to enjoy my music with.  I can say that I haven't thought about new gear or lusted for something more/different in a long while now.  Does that mean I'm "done"? Doubt it, I like "gear" too much!

I'm happy to discuss and answer any questions about stats and the gear I own.  I'm not interested in trying to convince anyone to listen to any particular headphone and I can't be arsed with justifying my choice of gear.

LOL, I forgot I sold you the Jades. Those were such pieces of shit in terms of construction, but after the mods, were the closet thing to an Orpheus in terms of sound. All the Jade samples do sound the same (I've heard three) and are very good after mods, but this particular pair did not buzz.

I don't think I mentioned to you that I had to shoehorn oversized screws into the fragile assembly to keep it from falling apart. If you have time, you should take pix and post them here.

The only concern I have with the new Jades / Jade II / or whatever HFM is going to call them (I hope HFM isn't pissed at me for calling them "Jade II", but we dont' exactly have an official codename to go by as of this moment) is that they will be voiced like the original stock Jades instead of these modded ones.

The 560 should be a good indicator Fang is capable of voicing a phone.  The question is whether he can translate it over to a new stat.

If I can finally finish making the case for the KGSSHV, ship is helping me build one.  He's trying to suck me into stats.   :&

n3rdling sent all of us on crazy runs after driving up to the first meet I threw in 2011.  I'm convinced this crazy train is because of him.

But- the $ amount of the TOTL stat rigs still seems big even though my dynamic stash still cost cash.

I'll have my time with stats soon, I need some phones that will sound good with the KGSSHV though. 

Ha, ship!  The Original Omegas (thought about buying them a couple of times) and the modded Jades are my favorites. 

Modded Jades on the prototype Electra were totally sweet-sounding, just a great balance of everything.  Sadly, those two pairs are not available.  Glad ship has them though!  If I could get those easily, I might be stats or have at least a rig already.  Or, if the production Electras sounded like the prototype Electra, I might have a KOSS ESP950/Electra Rig.

As it is, I've had to wrangle the heck out of the HD800 but can now make them sound good with any music that I throw at them and vary the sound as I wish.

For the KGSSHV:

I wonder if HE60 may be good. (Have heard varying reports of shrillness on some pairs- is that due to needing pads or "adjustments"?)

Also wonder if the 007 Mk. I will be to my liking with KGSSHV.  (I just heard the Mk. II on the KGSSHV and didn't quite like the tonal balance.)

Hope that the "not Jade II but the new model that comes out after the Jades and does not have a damn name yet" sounds good and can take some mods.  That just might pull people over.

Hear that the Lambda Pro is prolly the best value/sound in statland.  Think I will give that a whirl too!

Whoa a stax thread on Chang? These totally do not sound manly enough for pirates.

@CT

The KGSSHV can be tweaked to suit many tastes, but I don't think it can ever suit the 009s. For that I think modding the circuit would be required. I hated the stock KGSSHV sound, but after hearing different "versions" a friend has been putting out I'm really digging this amp. After all it's already sublime on the technicalities, it just needs a little flavor.

As for the HE60s, one variation of the KGSSHV in particular drove the HE60's so well it made me view them in a different light. It's comparable to when I plugged the 007/Omega into the BHSE for the first time (btw you're in for a treat ship ;)). There are still some spikes in the treble but they are much more tamed compared to before. Depth and clarity were both improved by a large margin, and the bass had a lot more weight and authority, but most importantly the grainy mids that I felt these had (compared with top Staxs) was fixed. Now they are my top cans for female vocals, right after the Omega + BHSE.

Not bad considering before I viewed these as an improved stat version of the HD650 in terms of sound signature (with the added bonus of causing hearing loss).

CT: How close are you to finishing your amp chassis design?  I know you were learning SolidWorks...are you gonna do any 3D stuff on the faceplate?  For my Megatron I'm leaning heavily towards using a non-metal chassis to make something more unique.  If it ends up picking up too much external noise (not shielded) then I'll just use the aluminum chassis I got from taobao.  I'm thinking of either an acrylic chassis or making lithophanes out of the panels, lit up with LED strips.  I think it will look pretty cool in the dark. :)

Regarding the HE60, I'm pretty sure most of the bad reviews are from sets with broken o-rings.  I've posted about this before, but basically the broken o-rings cause a loss of seal, which causes severe bass roll off and thus a kind of strained sound signature.  A functional set should sound a lot like a clearer HD600.  Build quality seems kinda cheap but most replacement parts aren't unreasonably expensive.

blue: What kind of mods did he make to the HV?  Actual circuit changes or specific parts?  I've heard a few different HVs and I think they may have sounded a bit different from one another.  I remember hearing an offboard HV/007 rig that had pretty insane bass, too much for my liking.  Another HV made the ESP950 sound better than I've ever heard it, with a much larger soundstage than stock.

Thank you, blue and n3rdling! 

This attention will help me get off my butt to contact the case manufacturer for specs and order the case.  Yep, just need to revise my design for the curved faceplate I was working on and got 3D prints of.  Need to resize for the case I am attaching to and cut the right spots for fixtures.  And then run by CNC operator for manufacturability check. 

The 3D prints were useful (especially the one at 1:1 scale) for showing me that my curves were a bit too dramatic and I am going to sculpt them to have the bit of "plateau" on the face with more flat vertical area that I had in one version but was having trouble reproducing when I lost the file.  Complex curves that vary challenge the tool (it's tricky to place the anchor points well) and don't easily make the transitions that I am trying for.  Good applied practice though- all the rudimentary shapes/faces are easy once you have run through exercises or solved problems along the way...

n3rdling, may I also propose that you could also make your own faceplate to start, retain the flexibility of using any bit of the aluminum chassis that you already have?  Then you benefit from the partial shielding, there is a clear spec to build the faceplate and prosepective custom body to...low risk?  That's how I am starting.  Then maybe some small amp full cases...for an O2 or something.

HE-60 O-rings, that's right!  I knew it was something like that.  I'll have to give a properly-functioning pair a shot, thank you!

Nice to know that the KGSSHV is a platform for a bit of possible tuning...will research later if there is a direction that I need to go. Have been concerned about TOTL solid state amps since it has been helpful to dial in tube amps to source and phones. [/size][size=78%]  [/size]

Had a little of exp with 2 SR-009 rigs, 1 with a Cary Signature and the Woo tranny and another with the Woo amp.

At the risk of sounding like a perv, I've always wanted to try out a Woo tranny. The simplicity of using a transformer box and having every transducer tie into one amp appeals to me, which is why I'm still kind of eying the Rag.

I'm not sure if my opinion of the SR-Omega being the most revealing transducer I've encountered is due to that actually being the case or due to its ability to resolve without any grain, etch, or other treble undesirables. I hope it's the former as I readily identified the HE60 as a notch below the HD 800 in resolving capability (although the HE60 "sounded" faster and cleaner).

I also thought my HE60s and SR-307s had aight bass that lacked impact and extension, but I feel that my Omegas have super-duper bass all around. The Omega do have the largest transducer of any Stax ever made IIRC (~90mm diameter) so maybe that counts for something. I haven't compared them closely enough against the SR-009 though.

The original Omegas have arguably the best balance of all Stax headphones. They don't sound laid back like the 007s and they don't sound as precarious as the 009s.

I love the x07 Lambdas, that upper bass bump and greater detail extraction due to the diaphragm change makes them a step above the x04s.

Yes, there's a certain weight or tactile feel the HD800 has that the STAX do not have. Not necessarily talking about bass impact, but rather tactility throughout the mids and the highs. This "etherealness" nonsense seems to be an issue which plagues STAX and not some of the other electrostatic headphones. The Orpheus and Jade had a certain tactile feel in from the mids on up which the STAX also did not possess.

BTW, I also felt the Orpheus and Jade were more resolving, better at extracting microdetail and especially better at microdynamic rendering, with the 009 sort of blacking out of dropping low level information. (Anax and I also directly compared BA/HD800 and T2DIY/009 - tonality, bass impact differences, overall presentation differences aside, the HD800 rig was better at microdetail extraction and microdynamic rendering, the 009 rig was less veiled and faster.) The 009 is still king of clarity.

In the end, I felt the electrostatic stuff was too niche, too screwball of a technology, too limited with good amp choices, too vintage (Senn Orpheus), too craptastic customer service (STAX) for me to stick with. If Senn had brought back the Orpheus, it would have been a different story for me.

I've listened to the 009s and the HD800s back to back a few times now and aside from the drastic change in presentation both are such detail monsters that I think it is irrelevant to judge the winner. While all staxen have that 50-60hz roll-off the Omegas still resolve all the way to the rumble. As far as artificiality goes I've been bothered by the diffusivity of the HD800s at times.

It's a shame that the small size and cult-ish status of the Stax market lead a considerable proportion of outsiders to regard them as some sort of "holy grail."

Hey, it's not the market's fault that esoterica comes off as cool.

But you never know. We didn't talk about DACs much until Anathallo started the "Not a lot of DAC talk thread in here". Now that DAC thread is the largest on this site. So maybe, just maybe 'tode had something in mind when he started this thread.

Yeah, I figured the accelerant would burn off quick enough and then we can keep the flame controlled and go back to the campfire tales.


I am curious how many pirates own a stat rig and are actually using it?

I definitely am. Could you please share some of your planar knowledge on the thread, I'm eager to learn of the factors contributing to etheriality.

With regard to other amps, hopefully the Vostok Sound electrostatic amps will find a few buyers once the final version is available. Based on all the "Stax Mafia" comments, maybe it's foolish to try to build, market, and sell a new electrostatic amp.

Healthy competition is never foolish.

Also high on my list are the Jecklin Floats.  Romy and I don't talk about them much publicly as we're sure to be put in straight jackets and locked up for heresy, but they are damned good! 

Yes, please tell. I have some ingrained aversion to the products of research by old mad German scientists. If the Floats have a one up in a couple of categories I will probably try them out.

Warren would be proud of this post.

I'm eager to learn of the factors contributing to etheriality

TBH, I don't have much experience with stats but I have come across this 'ethereal' kind of sound a few times while tweaking my orthos.

The two factors which seem to be associated with this are
1) Rolled off sub-bass
2) Shorter decay than natural

A combination of these two things leads to an ethereal/weightless kind of presentation also characterized by :

a)Excessively clean sound - mainly because of lack of bass and harmonics.
b)Excellent imaging and separation : My experience has been that presence of even excellent bass has a tendency to affect the instrument separation,the shorter decay also tends to cause the images to appear sharper.
c)Timbre issues esp. with accoustic instruments probably again because of the decay and lack of harmonics
d)Microdynamics seem to be esp. affected and it sounds a little bit compressed in that regard.(probably my main issue with this sort of presentation)
e) Low level information/ resolution - This one is interesting because on one hand these headphones sound very clean and have great imaging/separation which gives the impression of increased resolution. On the other hand, they have trouble with microdynamics, timbre issues and a short decay which affects the overall realism of the presentation. I expect people with differing priorities to have different opinions regarding this.
f) Vocals esp. male lacking body/reverb.

In my case, the effect was caused when a bass-light ortho was damped slightly more than what I would call 'critical damping'. I went on to 'fix' this by improving the bass and by reducing the damping slightly.

Ofcourse, most staxens hardly use any damping nowadays but they also have diaphragms that are extremely thin and would probably be affected by even a tiny bit of damping ( which may be caused by the foam at the back, the closed volume towards ear, the cups etc) and it may be possible that they are over-damped a bit.

Very true. While my earlier setup always had a lean/compressed sound that i attributed to my Yamaha HP1. With the new setup the sound is much fuller. And the most noticeable difference is in microdynamics; details are way more clear and available.

I have never given serious thought as to my lack of real interest in stats. It is not lack of exposure, I think I have heard ( and spent time with ) pretty much every stat I would care to. The German torture device does still appeal based on reports from Ship and MF. It is not that I find them offensive , I just don't find their sound signature to be natural. Guru summed the experience up pretty astutely in his discussion of "ethereal" quality. To me, listening to stats is like sitting in front of a wall of music - it has a massive soundfield which just comes at you in waves of crisply clean sound. Planar magnetics on the other hand have many of the characteristics of stats but the sound experience is more immersive. The musical experience is more realistic in the sense that I feel instruments have a natural tonal coloration ( similar to being present at the live event ) as opposed to sitting in a recording studio with the sound being mic'd and eq'd back at you. Yes, most recordings I listen to are just that so why should it make any difference. It probably relates to the type of music I listen to and how loud I listen at any given time. I have noticed that people who like stats often listen to a lot of metal and in all honesty, I have never heard Tool sound as good as it did from the Liquid Lightning mkII - SR009 being played louder than I would normally tolerate ( but substantially softer than many people listen to normally ). I always imagined that I would love a 4070 set up , closed headphones just make more sense for my listening habits. I preferred modded fostex planar magnetics. I guess what I am saying is that despite fairly extensive exposure to various stats (stax/koss/sennheiser/kingsound) and amps (cavalli/headamp/kgsshv/stax/transformer boxes) , there has not been a moment when I thought I needed to "upgrade" from planarmagnetic as the planarmegnetics offer more of what I look for in music reproduction than estats would. It is a personal preference.

Ummm yeah, you're right.  I'm not sure how my priorities play into it, but I'm a long way from agreeing with stats "having trouble with micro dynamics", especially the high end stuff.  Fed right, few headphones offer equal or better resolution.

My contention was that the bass(even excellent) tends to negative affect the cleanliness and instrument separation. The way I perceive it, the image of a musical instrument is composed mainly of two components - a sharply defined core which is mainly the higher frequencies and a more diffuse 'halo' around it which is the bass and harmonics. When we start shaving off on bass and harmonics, the images become cleaner and more defined and more separated from each other (almost floating freely ).  It might sound great with some music and give an impression of increased resolution but I don't consider the effect natural. Too much of a good thing for me, personally.

Umm, I didn't say that.I was discussing a specific presentation of planar headphones which seems to have become the 'house sound' of stax lately.It seems that someone over at Stax headquarters decided that the hyperclean ethereal presentation was the correct one. Some of us just don't find that  presentation natural.I actually don't doubt that a perfectly damped electrostat with good bass extension would in theory offer the 'pinnacle' of performance, its just that the Stax seems to have taken a wrong turn somewhere.

There are some other anectodal evidences that the Staxens may be overdamped.
1) Some members mentioning the older Stax models sounding more natural which have a thicker diaphragm and which would be damped lesser given same amount of damping.
2) I have read reports of people removing the foam at the back of their stax stats and finding it to sound better.

You mentioned that you like the Omega and Jade better than any other stat in your collection. Can you expound on that?
What is it that makes you prefer them to the current stax flagship SR009?

Yeah, I kind of expected those two to be contributing factors. I think these qualities are also true of the HD800.

I don't know about more natural, but the stats with thicker diaphragms definitely hit harder. It's likely a matter of taste. I tend to like a drier, quicker bass, but only to some extent (009 on the 727: yes; 009 on LL2: no). With orthos I don't like the TR50P bass stock, though it is OK after modding. I have heard an ortho damped to all hell that sacrificed bass volume and impact completely for smoother mids, it was an old T20 stuffed into a Sony ZX700 shell.

Anyway it's also worth pointing out that stat treble is really what stands above most orthos and dynamics. Speed there is essential and stats resolve timbral queues excellently. What's odd is that, to me, stats usually also have a more two-dimensional presentation with a notable hole in the center and little depth, kinda like dBel desribed it. Dynamics tend to provide a much better sense of envelopment. The least offensive in that respect that I've heard have been the Orpheus, 009, and Jade.

I really don't think it's a matter of rolled off sub-bass.  Most planars and stats extend very well to 20hz and beyond.  Plus many dynamics that roll off objectively even more have more weight and natural presence. The fact that older stats and Stax sound more natural when they have heavier diaphragms speaks volumes to me.  I still it's Force related to Mass.  If you think about all the natural instruments in existence, none of them vibrate air molecules with the same speed and low mass as modern Stax.  I find it an interesting discrepancy however misguided it may be.

I think what you're interpreting as short decay and sub-bass roll off actually isn't.  If the speed/acceleration is there, which it is for stats, decay should be transparent to the recording material be reproduced.  Technically it appears to be based on the CSDs showing them to be more ideal than others.  However, listening just seems to indicate something is off, and this is true for the planar speakers too IME.  Rather than roll-off or decay, I think this is another case just like DACs and amps where we need to consider that there is a missing metric that needs to be considered.  This is a typical case of technological development outpacing standardized metrics which causes people's ears to be perplexed when compared with what they see in their measurements.  In this case, I think there needs to be established some sort of minimal 'F' point (Force) where mass and acceleration can provide the necessary impact to drive a certain volume of air molecules a certain speed.  I mean, if we make a driver out of photons with immense acceleration, how would that sound?  Probably not very good.  Err, correction, probably not at all.

Simple: position two pulsars on opposing sides of a nebula that's bisected by a solar sail, each equidistant and perpendicular to the sail's center. Modulate their respective rotational periods and you'll have a cosmic stat.

Its not just a matter of rolled of sub-bass but a combination of factors which also include a relative lack of harmonics and a shorter than natural decay.

I don't agree that just because stats have a lower mass, that they are capable of maintaining that speed/acceleration at all stages of driver motion.

Many people seem to hold a notion that the trouble with the heavier diaphragms of ortho/dynamics is that it is not capable of achieving the speed/acceleration that a lighter diaphragm can which is incorrect. If you provide enough force than the driver in spite of its mass would attain the desired acceleration and ergo speed. The trouble is that by achieving that speed coupled to its mass, it gains a massive momentum which can not be controlled just by the electromagnetic input of the driver. It must have some form of mechanical damping to retard that momentum so that it stops when its being asked to. Since it won't stop when it should, it starts oscillating at a frequency most of you speaker guys would know as the primary resonant frequency of that driver (for behaviour in free air). As this frequency is usually somewhere in the bass region, you get a headphone with bloated bass, lack of resolution/transparency, and overall a thicker sound with longer than natural decay.

The electrostats have the reverse problem, they too attain the speed/acceleration but probably never enough momentum. If there is even a small amount of external damping present , then the driver would decelerate quicker than it should and it would actually be movement restricted at the extremes. I believe that it is that restriction of movement that leads to a shorter than natural decay and compression of microdynamics.

An ideally damped driver would of course be in a such a state of equilibrium that it would no longer be affected by any of the mechanical factors. It would accelerate, move, stop, turn and then accelerate again at the sole discretion of the signal governing it.

In this case, I think there needs to be established some sort of minimal 'F' point (Force) where mass and acceleration can provide the necessary impact to drive a certain volume of air molecules a certain speed.  I mean, if we make a driver out of photons with immense acceleration, how would that sound?  Probably not very good.  Err, correction, probably not at all.
Exactly, I am actually saying the same thing. It won't produce a sound because despite its supposed immense acceleration, its motion would be completely negated by the mechanical damping effect of air. Yup, this one's overdamped too!

Thanks gurubhai. You explained that in a way that even I could understand

So here is the question, could you imitate the sound of a 007/009 by overdamping an ortho and articually reducing decay.

Could this also be the reason why power is important regardless of db attained during playback? Power is necessary to provide the acceleration needed to overcome over damping, thereby improving microdynamics and producing a more natural decay?

Right, I agree on the importance of damping.  I was just talking about the same issue from the PoV of the driver's mass itself.  We are saying the same thing from two sides of the same coin I think.

I don't agree with the notion that stats underachieve at microdynamics...at all.  I think they actually excel in this area.  I would have expected somebody to say that about their macrodynamics if anything.

I'm also with ship about "sub bass roll off" not being what causes their sound.  Many don't have sub bass roll off, and like he said they have the same sound even when there's no sub bass at the time on the recording.

I don't agree they have an unnaturally short decay...the ideal decay is no decay.  The decay lasts on the recording and should last no longer than that.

When you guys say the older Stax sound more natural because they have thicker diaphragms, which older Stax in particular?  It's also not entirely true that the newer stuff uses thinner diaphragms.  It has varied up and down between about 1 and 2 microns from the original Lambda to the current stuff.  Another wrench the throw into that argument for some ears: the Orpheus uses a 1 micron diaphragm, as thin as anything Stax has ever used.

I think the biggest contributors to the "electrostatic sound" are the tiny excursion and the relative lack of damping on the backwave.

That's cheating, you added a mass driver with the solar sail.  Fun idea though to potentially stave off an alien invasion, just need to add some Nicky Minaj to the mix.  Truth be told, I actually like a few of her songs, but it's an acquired taste.

I suppose you could remove the solar sail and instead depend on the excitation of plasma within the nebula. Kind of hard to get around the mass thing though, given that even space is quantum foam. A wormhole might still work for playing Led Zep with gravitational waves.

I think the tiny excursion and the lack of damping on the backwave may contribute to low non-linear distortion.

I think the "ethereal" signature is proly somewhat a result of a characteristic depression in the upper midrange, which might also be somewhat rough relative to other TOTL cans using a different driver technology.

As far as the sub-bass response, more than a classic roll-off I think Stax cans in general exhibit a sub-bass drop relative to the upper bass. Sub-bass is definitively there, but below the upper bass and indeed below most of the midrange. The upper treble is also there, but also below the upper bass, midrange, and some portions of the lower treble.

This IMO translates into a sort of U-shapped (scooped) upper midrange, and a de-emphasised lower bass and treble. That is, to me, these cans are not w/o their characteristic coloration. They have their strengths of course.

Here you get into the question of monitoring equipment where the engineers reference is most likely a dynamic, especially for the bass. Even if the monitor is a filtered or servo'd high end sub you're still left with the room's resonance modes. The decay is short in comparison to the vast majority of the commonly used options and might not adequately compensate for the mix. If you're used to stats (i.e. they are your reference) and the recording you're listening to is binaural and mixed with something like the 4070, then you indeed get unparalleled performance.


When you guys say the older Stax sound more natural because they have thicker diaphragms, which older Stax in particular? 

For me the revelation was a 2-3 micron DIY stat Frank had on loan from that head-fi maestro whose name escapes me.


So here is the question, could you imitate the sound of a 007/009 by overdamping an ortho and articually reducing decay.

It's all about balance and getting the best sound relative to the starting point of the stock headphone. An overdamped ortho sounds like crap to me, though I think there are a few DIYers who prefer it that way.

The upper midrange depression may also contribute to the dimensional flatness because of the subdued directional queues found in that frequency range.

The ethereality may be due to a number of factors and it should be noted that most people simply aren't used to stat-like presentation. Unless I go for a few weeks without listening to Stax I do not notice as much of a difference, likely because of conditioning.

Yes. It's easy for me to become used to a particular headphone and tell differences mostly in a relative sense... unless things are severely effed up, which most Stax IMO are not.

I was not successful in getting my ears accustomed to the DT-990s, Audeos (good detail though), stock T50RPs (need modding), some RCA IEM bullshit, among other cans.

Its relative, the ethereal planar I was speaking about still had better microdynamics than a LCD-2. Question to you - Is their a difference in microdynamic rendering between your more ethereal sounding stats and the orpheus?

I'm also with ship about "sub bass roll off" not being what causes their sound.  Many don't have sub bass roll off, and like he said they have the same sound even when there's no sub bass at the time on the recording.
If the recording itself doesn't contain much bass then it itself contributes to the excessively clean sound of the stats. I am not getting the discrepancy here

I don't agree they have an unnaturally short decay...the ideal decay is no decay.  The decay lasts on the recording and should last no longer than that.
I was talking about the perceived decay of recorded instruments. An ideal transducer would leave that as its is, neither shortening or prolonging it. My experience with stats has been that they seem to be seem shorten that decay while the underdamped orthos seem to be prolong it.
When you guys say the older Stax sound more natural because they have thicker diaphragms, which older Stax in particular?  It's also not entirely true that the newer stuff uses thinner diaphragms.  It has varied up and down between about 1 and 2 microns from the original Lambda to the current stuff.  Another wrench the throw into that argument for some ears: the Orpheus uses a 1 micron diaphragm, as thin as anything Stax has ever used.

I think the biggest contributors to the "electrostatic sound" are the tiny excursion and the relative lack of damping on the backwave. 
I previously left it out for the sake of simplicity, but their are of course more variables to the complex equations governing the motion of diaphragm than just its mass and the external damping. There are factors intrinsic to diaphragm such as its tension and elasticity which also affect how much would move.
Also the different cup volumes, enclosed volume at ear side, baffle vent etc. all affect the resonant frequency of the transducer.
What I am saying is that you can't simply compare two completely different headphones by just the mass of their diaphragms.
On the other hand most lambda models are almost identical and the only difference are at times just the difference in their diaphragm mass. In that case, it would probably be reasonable to assume that the headphone with heavier diaphragm would have a thicker sound.

Frank's DIY stats were from Chinsetta Wong.

Flatness in the soundscape has little to do with the ethereal quality IMHO.  You can get that from any number of dynamic headphones and even DAC's and amps.  None of which ever give the hint of ethereality.  I really think looking at FR is the wrong place since you can find any amount of cans with similar FR and not have the problem but I digress, always easiest to go with what we are familiar with I guess.  I've heard planar panels with subs and they pretty much all have the same stat timbre but to various degrees (Sanders most, Magnepan least).

Actually the Orpheus that Sennheiser uses for demo does have the ethereal quality too.  I suspect other HE90s that have less of it can attribute that to the state of the paired amps or other potential sources of degradation over time.  HE60 has a little of this compared to the 600/650/800 too but the Senns tend to be less obvious than the modern Staxen.  Personally I feel my SRXmk3 sounds more natural (definitely less proficient) than the more recent stats, problem is I have two and one sounds different than the other so I can't comment on what other people have heard in the SRX lineup.

As for psychoacoustics, I call BS on that being any sort of reference for what I hope are obvious reasons.  I don't buy into the myth that humans have the auditory memory of a brain damaged gnat.  Many of us have heard pianos, violins and other real instruments and how good and accurate they can sound on a reference quality binaural recording.  The idea that a musician forgets the sound of his own instrument after just 10 seconds is just beyond stupid.  Therefore, listening comparisons based on memory can be valid if done properly and even level matching by ear has been shown to be quite accurate (within even tenths of a dB) even without measurements.  If you use a known quality recording for reference and you have to 'adjust' your brains and ears over time to get used to it, that's just a plain admission something is colored and inaccurate.  Your standard reference should be how your ears hear in the natural world without any phones or speakers.  Perfect transparency is not knowing you are listening to speakers or headphones at all.

The low non linear distortion is pretty much due to the balanced drive and centered film.  The field forces are equal between stators. 

I kinda doubt the "electrostatic sound" is even FR related since you can instantly tell an electrostat apart from a dynamic even though different electrostatic headphones and speaker panels have different FRs.  Maybe somebody with a good PEQ can apply the filters you suggest to a standard dynamic headphone to test your idea.

Planars are going to sound different from dynamics right off the bat just because the wavefront is drastically different.  With orthos and stats the entire active area is radiating sound in a piston-like manner, and this is typically a pretty large surface area.  Stats and orthos differ in their spacer thickness and damping.  The spacer thickness is related to excursion, which is why orthos tend to have much more impact than stats.  Orthos usually use much more damping in order to control the diaphragm and help linearize the FR, but doing so hurts the openness/soundstaging.  I don't like orthos that use lots of damping for this reason...they sound too closed in and too much like headphones if that makes any sense.  I don't like being aware of the driver right next to my ear as it distracts me.  This is what I mean by "driver transparency" from time to time.  Stats also have the advantage of better acoustic transparency between the diaphragm and the ear (thin, uniform open stator vs array of magnets and holsters), though the single ended orthos are now tops in this area.  Single sided electrostats are possible, but I don't think practical...you'd have to find the sweet spot for spacer thickness without a drastic increase in distortion and I don't think anybody has been successful in doing so.

Perfect transparency is not knowing you are listening to speakers or headphones at all.

That I agree strongly. I think in the previous "THE Show" headphone discussion panel, I heard plenty of times how a particular headphone sounded "crazy good" because it sounded like speakers. That is great (depending on the speakers and room), but I would rather like headphones to sound like a real life venue instead (or as close as possible to it).

It would be nice to hear Nirvana or a Jazz play in their setting, as opposed to a great set of speakers in my bathroom.

Many cues in the FR magnitude can hint some issues, but not all.

In all fairness, FR measurements depend on coupling among other things so I agree one most not get carried away looking at them. I look at some stuff here and there to try to explain some things, but that doesn't make it the ultimate explanation, or even the correct one.

As far as distortion, I still feel its somewhat related to the tiny excursion. When driving a headphone loud vs moderately the one thing that I find changes the most is non-linear distortion. Driving a headphone loud changes the excursion from tiny, to not so tiny. With stats, probably going for loud still results in relatively tiny excursions relative to other driver technologies.

I also feel that it's a bit difficult to emulate the exact response of a headphone with this or that EQ, even if the problem was only 2 dimensional, which I don't think it is. That said, I know some here feel that appropriate application of an equalizer can benefit Stats in general, and I agree with that. It can also make some cans sound close, but not perfectly close. This is probably more true if one is going for critical listening.

n3rdling, the macrodynamics swings were very noticeable for me with the 717/009.  007 sounded much more cohesive as a whole with a better soundstage.  They were a bit too dark for my tastes but it sounds like that has a lot to do with amplifiers.

I think something that often gets overlooked with stats is how damn comfy they are.  It isn't just the weight either.  The pads and headband design are extremely erogonomics.

Post by: Anaxilus on May 27, 2014, 02:00:27 AM
I dunno about that, I think Stax runs a wide gamut of ergonomics.  I personally never liked the fit of the 007.  The pads always seem to be reversed or need to be reversed and the headband I guess needs to be bent to fit your head. Pretty much everytime I put on a 007 it feels like I'm wearing it wrong.  009 works out better for me.  Personally I think an ESP950 design is better than most Stax but they use cheap materials.

So here is the question, could you imitate the sound of a 007/009 by overdamping an ortho and articually reducing decay.

I don't think that its possible to imitate the sound of a specific headphone by modification. We can, however imitate the weightless ethereal presentation of stats in orthos by the means of damping. If you could have been here for our last meet a week back, you would have heard it for yourself.


Could this also be the reason why power is important regardless of db attained during playback? Power is necessary to provide the acceleration needed to overcome over damping, thereby improving microdynamics and producing a more natural decay?
Its well known among modders that damping affects the sensitivity of a driver. The more you damp a driver, the less sensitive it becomes. The first generation Hifiman orthos employed a lot of damping and it was one of the reason for them being so challenging a load to drive (The other being their very low impedance). The later Hifiman have avoided damping and that contributes to them being easier to driver than the previous generation.
As for more power improving the microdynamics and decay of a headphone, it just hasn't been my experience. Improved bass and macrodynamics may be, but the best microdynamics/decay I have experienced has been from comparatively flea powered tube amps.

As for weight/comfort of stats, I would agree. My PMB float is by far the most comfortable headphone I have ever placed on this noggin.

I suspect most stats are more heavily damped than we give them credit for. The dust covers actually do a very fine job of damping. I noticed just how much while playing about with Ship's Kingsound. One of the most appealing stats to me is the sadly forgotten SRX mkIII pro - I have heard a few examples, the modded ones win me over any TOTL sax.

I am not sure if Ship or anyone else who has heard his Kingsounds agrees , but they sound more like orthodynamic than anything else

One more thought - has anyone ever looked at phase shift in stats - perhaps the dust cover causes some degree of phase shiftiness and this messes with the wannabe ethereal acoustic centers in the brain.

A little like the cause of rainbow schizophrenia, there is bound to be some interweb data to support this theory.

I think the shape of the diaphragm has an influence on said "etherealness", as the older Staxen (and omegas) have a circular diaphragm as opposed to the rectangular diaphragm in the Lambda line, whose sound I never liked very much despite being more balanced FR wise than the older Staxen. The Sony ECR-800 with its pentagonal driver has a rather different and somewhat meatier sound, even compared to vintage Staxen which had diaphragms of similar thickness (2um).

Rant: God damn Sony and their planned obsolescence. When I got my set, the cable had melted into a plasticine-like goo, and the headband would fall apart just from sitting on my head.
