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.

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.
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.

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.

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.

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.


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

Here you get into the question of monitoring equipment where the engineers reference is most likely a dynamic, especially for the bass.

Those were made by chinsettawong, I have them here.  FWIW he used 2 micron Mylar on these, and I agree they sound lovely. :)
