Hmm, I would have to disagree with you there, the bass on my HD800 is excellent when its got a decent amp :P
(not the boomy high-impact "good", but very detailed, deep and exact)
The stax actually feels like it comes up short to the HD800 in detail for the sub bass.
And having spent a few days with Fostex HP-A8C and my HD800 I would mostly agree with you that it does well on low volumes, but for its price I expected more. (also the usb issue I mentioned before...)
After burning in HD800.. I must say that this headphone has BASS. Note that this statement comes from a Denon AH-D2000 owner, a closed headphone which has advantage in bass area compared to the open ones.. so you can figure it out :). I don't have the Denon with with me at the moment but I'm pretty sure HD 800 does not lacking in this area. It's accurate and controlled.
There is no issue on USB at all, just use Wasapi exclusive.. You can check this site
Or you're talking about USB DSD files support? Do you have many of that files?
So guys.. what is the expected price of new Sennheiser electrostatic flagship then .
Actually, I don't know which area could be improved with this HD800 ... I'm very satisfied already with the performance... May be I should get a Luxman amp (may be top choice for SS) or even Leben (may be top choice for Tubes)?
