Could someone with the TH900 and/or TH600 confirm whether or not they use the same earpads?
I find the TH600 in stock configuration to sound "better" than the early D7000, but I seem to prefer the late-model D2000 directly.
Vis-à-vis the D2000, I find the TH600 to have noticeably tighter bass and superior fundamentals. Its main issues are relative stridency in the 6KHz region and a very noticeable midrange suckout. While the Fostex certainly produces more technical finesse, I prefer the D2000 for its fuller sound signature.
One aspect I found curious was that the D2000 appears to have superior sub-bass response. We know that the Denon drivers are masters of distortion (in the bad sense) below 50Hz, so I did some playing around. When I swapped the pads, I noticed that the D2000 sounded noticeably thinner than with their stock pads -- sub-bass response was weakened and bleeding as well.
I'll have to experiment more with the D2000 pads on the TH600 just before I ship them out. I'm a little curious why Fostex ditched the superbly-fitting later Denon earpads for this less-contoured (albeit lighter and more comfortable) eggshell leather jazz.
