i don't mean to make a thread but i guess i like to share my experience with first pair of electrostatics i ever had a chance to put on my head.


i was loaned these by a very kind person to give the ''electrostatic'' sound a try. also he was very curious how i think it would compare with the SA5000 and 240DF's. i gotten them this monday and so far i actually really like how they sound so far. thing i have to mention these aren't exact SR-202. they actually using pair of stax lambda pro ear pads,handband cushion  and i believe he said also they're using the lambda pro frame as well but the drivers are indeed the sr-202 so i don't know if that'll have anything to do with it or not.

the little amp is actually very interesting cause i never saw pair of electrostatic headphones use this before. usually they use a big box to be used off of speaker outputs of a power amp(receiver or integrated amp as well). right now i just have them off the pre-outs of my h/k 725 preamp. i was kinda concern the high voltage from the pre-outs in combination of +4dbu gain from my interface would overload the inputs and clip it like crazy but it handles very very well. i only use the pre-outs cause they do not respond well to soft-ware eq'ing whatsoever but respond very well to the tone control buttons on my pre.

i haven't compared it to my other headphones or my speakers yet and i been having less time to listen to these cause you need a complete quiet room to hear these perfectly so i only listen to them early in the morning. i'm also use to my other headphones as well so i could pick up those right away and adjust to the sound. this first time using these but right away when i turned them on i noticed good midrange tonality and clarity. they also manage to be very transparent to the source with no need of boosted top-end or air and are actually super smooth...like really smooth. must be because of their complete open design or this is what ''electrostatic'' speed really is. it's hard to explain really cause everyone knows i suck at this type of stuff.

they're not bright by any means. they seem to have pretty relaxed top-end but very present,detailed and don't sound harsh,shrill or all that fun audio terms, but some odd reason they actually have pretty good extension in the process. i read the box(amp) caps out or something  at 20khz so i ran it through sinegen running at 24-bit/96khz and seems extend pretty well up to 19khz but it could be possibility of my ears limitations or harmonic distortion. i have no idea to be honest. they do sound like there might be some upper-midrange to the lower-treble recession but that just might be the song/track. seem to lack bit of top-end to air as well but that just might be me cause i'm so use to my other headphones having good amount of air. i can't say for sure.

i heard complaints about bass with lot of electrostatics and stax but to be honest i find nothing wrong here with these. yea they're not fart canons of any sort like lot of dynamics or planers(only planers i heard are a modded yamaha hp-1 and my fostex of course but they gave me headaches and vibrated my head when i tested lot of bass competition tracks on them). but they give a good amount of punch to the kicks and good amount of impact. i did go through a run through in sine gen as well and they seem to extend down to 50hz and after that take a dive but down to 40hz is pretty audible. below 40hz it just caps out. nothing is heard or felt but that must be the driver limitation since low-bass and sub-bass needs massive amounts of air to push so the diaphragm might not be strong enough(or can be amp as well maybe cause low-bass and sub-bass takes lot more power compared to high frequencies).

so far with the right song they sound really clear and sound good with good amount low-level information. these are just quick impressions cause i listen to so many types of music and very diverse in my taste that it's always so hard to take a consistent decision on my part but i do like how they sound so far. sorry for the wall of text. i don't realize how much i type till i preview it.

Good write-up, Rex. Thanks for sharing.

I'm not sure how the SR-202 and the Lambda SB differs, but a lot of your impressions mirror mine when I had the Lambdas for a couple of months. That "relaxed, but extremely detailed" was a revelation to me -- especially after coming from Grados. I couldn't fathom how to have a fast and detailed yet non-fatiguing sound until I heard that famous "Stax effortlessness". It's a strange concept that completely "wow'd" me when I first heard it -- although eventually I found it a bit too polite for more aggressive music like rock, hip-hop or faster electronic. That Stax effortlessness is not conducive to the head nod.

I also had issues with the bass and the imaging. It was a tad bass-lite, and lacked texture -- was very soul-less. The imaging surprised me because the person who loaned it to me heralded it for its superb pinpoint imaging. That was the case left and right, but there was a lack of spatial cues on the Z-axis. It was very two-dimensional -- as if the the music was painted on a flat canvas in front of me, rather than a 3D sound field. The imaging gripes may have been an amping issue, although I tried it on both my Marantz 2220b and Allied 498 out of the speaker taps through the transformer box.

All in all, a very cool headphone, but not something I could live with as my primary. The OII and 009 are a big step up.

no prob. sharing is caring   ;D

these SR-202 are bit different to the stock SR-202. these use a pair of lambda pro ear pads,handband cushion and frame. these were actually restored by the owner and was told that before he sent them out to me.i have no idea if that affect the sound of them big time or not but i can't say since i never heard a stock SR-202 before. i have them for couple months so i have more then enough time to enjoy them then i have to send them back :'(

i find the bass enjoyable here with nice punch but not much extension. i don't know if cause how well they seal due to the pads or what. the bass is probably mix between my fostex and DF's detail/texture wise(am i saying it right? i have no idea). i don't have my fostex anymore and i haven't compared to any other headphone so this is going by memory.

it does have good separation but i will admit the imaging is not like my DF's and the SA5000 cause there is not much front or back depth and not able to go very wide either but i think that might be lack of air they have cause both my DF's and the sa5000 do have more then good enough air in their FR(air dispersion helps lot with imaging). it's soundstage(instrument separation) is pretty well pin-point and comparable to speaker soundstaging(stereo can give a full 360 degree soundstage with a good room and speakers).

after hearing these though i kinda want to get a chance to try pair of stax lambda pro. i heard their slightly brighter compared to other stax so i might like those as well(i will admit i like headphones bit brighter then others but only if it's super smooth. not harsh or piercing. mostly what i mean is something not rolled off in the air response. i don't like bright midrange or a peaky top-end and cause i usually listen to headphones not very loud where i can still hear myself talk. helps me focus more).

i do love the midrange the most and it's very nice listening to KD Lang and Diana Krall and i'm usually a midrange whore as well besides like good air response. not much a bass head or bass freak but do appreciate a good tight and well extended bass response but not very important to me as long it has a nice impact(impact i believe is around 50hz).

i never tried them on any of my speaker amps since these use a little box that connects to either pre-outs or tape-outs instead and has it's own little built-in stax amp(SRM-212) so personally i do not know if there is room for improvement with these.

I really liked the SR-Lambda SB when I heard it.

I have this crazy idea about taking a Lambda and modding it into what amounts to a ghetto-rigged 4070 sine I need  some isolation.

i did about hour comprehension to the SA5000 back and forth over and over and over same song and right away they sounded different from each other but it defiantly showed in electronic music how much air is lacking with the stax. even though the stax are ear speakers and completely open and i know with electrostats seal and positioning most important but no matter what the sa5000 had a more open and speaker like center imaging than the stax. i don't if cause more air on the sa5000 or what. but the stax defiantly lack no top-end. it at least does that wonderfully. i find the SA5000 as quick as well but maybe bit quicker in resolving layers of information on quicker songs but that might be because the air response of the SA5000 so i can't say for sure since i'm no professional. the stax do sound more closed in than the sa5000 for sure. if i had pick one for matter of preference i think i stick with the sa5000.

might be gear but difference is just amp really. both using same source and preamp. i read the srm-212 amp is a class A stax amp so i ran my yamaha m-45 in class A as well just to be somewhat fair but i know they're completely different overall. maybe if the SR-202 had pro bias stax adapter for speaker outputs it might of help or not but i think if the srm-212 was design to perfectly match the sr-202 then it's driving it more then fine i assume.

i take it, it's probably really hard to carefully mod electrostatics due to the very thin like drivers. i bet it's pain probably just cleaning them if any dust or hair manages to get inside.

I don't think you'd have to go as far disassembling the drivers or anything.

The grills just come straight off the back so I could replace them with something solid and even switch them back and forth as ambient noise permitted.  The rear side dust cover should keep the driver safe.  The hard part is keeping it from ruining the sound but I've read that the 4070 just uses a normal Lambda driver so the enclosure is the only thing that should need messing with.

alrighty then. i get it now. i thought for a sec that the drivers were specially embedded into the enclosure so might need to take the driver out.

i might try to hunt down a lambda pro maybe sometime near the future to try. the SR-202 with the lambda pro pads is the only electrostatic i heard so far. i had many opportunities to score a koss ESP-9 dirt cheap but always passed it up for some reason.
