Yeah, thanks fellas. And nice work Don, Scompton and LFF! And Tyll!!
Chi-uni-fi sounds like a secret fraternity, but I'd pledge if I were you. Besides, you already live there. So just go and attend the hell out of it.
Moving drivers forward increases separation? do you mean they'd start to approach the Sigma's headstage?
I have both their albums. RSQ. Great band. But yeah, why not a DIY Sigma? There's always something unnatural about headphones always clinging to your ears like some alien with an earlobe fetish. I can easily appreciate Naotake Hayashi's frustration with headphones always feeling and sounding like #$% headphones, no matter how good you made the driver.
Do you have signatures turned off or something? Chi-uni-fi has been in mine for a while now.
I think most headphones have a little better depth to the soundstage when I wear them so that the center of the driver is forward of and lower than my ear canal. The AD1000's driver is held in place by a plastic ring that's kind of deep and I think that putting the YHD-1 driver off center and too close to the edge might end up making some weird reflection or something.
Have you tried something like that with other headphones and got too much L/R separation? My current T50RPs have the drivers very angled and a little forward due to the way the pads are mounted and it makes the soundstage fairly narrow but very deep. The difference in sound stage when I was A/Bing the AD1000 with the T50RP was startling. The T50RPs had so much more forward projection that they might as well have been speakers in comparison. That was only using the crossfeed on my Leckerton UHA-4 and not TB Isone which I normally use for my listening at home.
Those pads look nice. I think memory foam would be a good choice for stuffing. Its pretty good at absorbing energy and not bouncing. I have a Tempurpedic bed and if you drop something on to it it hardly bounces at all, even if whatever you dropped is elastic itself. Something dense and inelastic won't even bounce at all. If the memory foam I ordered ever comes in I'll tell you how it works out. My Ultrasuede pads are already stitched up on 3 sides and are just waiting for the foam.
The lambskin pads I'm using now have some kind of memory foam in them that works pretty well for keeping that "spring" out of the system. Its either lower grade, just firmer, or something else though so they don't conform too well to my head.
Congrats to all!
And yes thanks to Tyll also not so much for the contest aspect, which is incredibly generous as it is, but for taking the time to help out with the measurements.

1 ) Ime, and this doesn't sound like many people agree, moving drivers forward like that makes L/R separation way too extreme. Judging by your comment I'd say you agree with me in that almost no matter what you do stereo separation is the bane of any headphone's existence.
2 ) I will check them out and look him up. Lol.
3 ) I figured memory foam would be the next best thing to gel (maybe even better due to weight... can you imagine a 90mm iso driver with lead filled pads?
It's a pleasure, mate!

That kind of gel is really cool. It's a shame you cant really cut it. It more or less has to be made in the shape you want it.
Likewise. You had a preview of it with RD's Yamaha, but I think you're going to see the Next Step in DIY orthowrangling soon.
Customary random thought: On the subject of measuring headphones, is there anything that replicates human perspiration in a dummy head? My CD850's sound like crud at first, but after a few minutes the pads get slightly tacky which improves, well, everything.
Good point. I sometimes go out for a run and work up a good sweat. Then I rub my armpits all over the head before I test the DIY cans.
A little Lysol should fix that up guys.

There's lots of waste cutting it down to form. More would go to the trash than was actually used unless you were creative with scraps somehow.
That other impact gel definitely needs a form fitting container, though. It's like a putty/paste along the same vein as the Borax/glue substance I was talking about. Unless you talk to the manufacturer and get them to make custom pads in bulk you'd have to buy a two-ton bucket of the stuff and who knows where you'd be then.

That'd probably be just as good if you could think of a way to encase it.

Plus just replicating body temperature. That's got to be important for anything with memory-ish foam pads or foam IEM tips.

Wait. Who's doing what with Next Step Yamaha mods? What do you know that I don't?
Is this similar to the " Husk Musk " Kids in the Hall skit?
