Differences in SR-007 pads
« on: October 22, 2012, 06:36:51 PM »
Finally managed to find the time to take some comparative shots:


Slightly older model (going by SN):





Slightly newer model:





The difference is even more obvious to the naked eye than the pictures make it out to be.  It was also fairly obvious when listening right off the bat, which is why I came to inspect them at all - the one with thicker (and more tightly woven) grill cloth sounded less transparent (slight veil I guess) than the one with the thinner cloth.

The normal bias SR-Lambda is my personal favorite of the Lambdas I've heard (which are roughly in order: SR-407, SR-202, SR-407LE, SR-507, Nova Signature, Normal Bias, and Signature). The Nova Signature is a close second, followed by the SR-507. The Signature (non-Nova) was too bright to my ears, though it could have been the setup I heard it on at the time.

Hehe.  I guess I just need an amp then if I'm already that close to the top.  Or at least my top.  The 009 is out of my league  Probably the O2 as well, though I'm not sure if I'd like it's FR as much.

Now I 'just' need to find a good design that doesn't use bins full of rare transistors or double as a space heater...

@ Tari:

Thanks for the pictures of the two. My SR-007 is definitely closer to the top picture with the thinner material. Hmm...

I'm not sure what to attribute it to - maybe original stax pads vs some facsimile sold by joynet?  I haven't even tried taking off the pads yet.


Justin has posted PDF's for the new Stax models:

Looks like the new portable will have 4 hours of effective battery life.  I wonder if an adapter could be made  to try to take 007's on the go (cue Googleli here).

Yes.  I've played with O2 pads on orthos a lot, and that dust cloth has a significant impact on SQ.  I didn't actually think it would, and so wasn't paying attention to it.  But I noticed it when a damping scheme was ruined after I added the dust cloth back to a scheme I had been working on without it.  It was suddenly veiled and dull sounding.  I thought I must have messed up and it must be the midnight rose colored glasses, but on a whim, I removed the cloth, and it sounded good again.  That stock cloth doesn't really change the FR, it just dulls down the sound.  I don't imagine it could sound harsh without it.  But you'd have to experiment. 

If it sounds better without, you could remove it altogether from your O2 and replace it with legging material.  There is a plastic O ring that holds this cloth, and that O ring comes right out of the earpad (it's not attached), so you could easily cut out the stock cloth, and then glue leggins onto this O ring and put it back into the pad.  You'd have to remove the pads from the phones to do this.  Here's the best way to do that in case anyone wants to.  This is how I rescreened my Sextett.

cut out stock cloth
find a flat board, like a cutting board that you're ok putting some holes into
stretch a peice of legging material big enough to fit O ring out, and use tacks to hold it stretched evenly (not stretched too tight, just a bit so it's even and flat)
then glue the O ring onto this with whatever glue would be best.  Maybe super glue.  use quick drying glue and make sure you don't glue the ring onto the board below.  Use a spatula or something, running underneath periodically to make sure it's separate. 

At your own risk of course.

RD, do you have any stax pads at home you could try this with? I'd pay you for them to try it out - I just don't want to ruin my essentially NOS pads if I end up selling the headphones.


I'm not surprised it makes a difference, I thought it changed the Audeze sound not insignificantly.  I think Kabeer has similar theories.

I don't have time, but I do have some pads, and if someone else wants to do it, I could send them the O ring that holds the speaker cloth. 

It's kind of a win win situation though if you first try just taking out teh cloth all together and see how it sounds.  This is totally reversible, and won't damage anything.  The O ring with the cloth is just held in the folds of the earpads.  Might not want to leave it unprotected for a long time, but you could hear the difference that way.

I'll try that when I get home.  I assume naked sounds better (based on how the thinner weave sounded better) but dust seems like an issue, no?

hmmm yeah I have read about stats being sensitive to dust so maybe there's a reason for a thick fabric there.  I don't know about that one.  But trying it temporarily won't hurt, dust is a problem when they're sitting around, not on your head. 

Seems like leggings would offer just as much dust protection but I don't really know.
