A few questions:
Those of you driving the TH600 from a powerful amp like the Lyr or equivalent. Do you get a noticeable noise floor/hum? Is it as bad as it was for the old Denon line?
So the TH600 are tamer in the bass, less recessed in the mid (But drier), but the treble is harsher than the TH900? With some people detecting minor sibilance and other people detecting none?
Oh and the TH900 offers more resolution and detail extraction?
I think that's the gist of what I got from all my reading. One questions I did have is, does it offer more transparency/resolution than the LCD-2 or HE-500? or a little less than this guess? It is grainier than these planars right?
Bass is more polite than the TH-900. Seems like their is more of a sub-bass presence but IMO that is just because the TH-900 has a slight emphasis in the mid-bass. So yes, the TH-600's bass does sound more linear. The mids are less recessed, but not as sweet and lush sounding - yes, drier. Treble is not as refined, but still extends very well and has nice detail. Sibilance was at a minimum with both headphones, but there was more with the TH-600 (some female vocals to be exact).
The TH-900 does do better with technicalities. Better resolution, slightly wider soundstage (depth is about the same to me), more detail from top to bottom, and imaging. Overall a slight more natural sounding headphone in comparison. I've said it to a few people before, but if I were to put a number on how much better the TH-600 is to the TH-900 it would be 90%. Value wise - the TH-600 is the clear winner IMO... just don't put those red cups around your ears and you will be fine.
Transparency/resolution is better than the LCD-2, IMO. A very close comparison to the HE-500, but I think the HE-500 wins out in the end. Especially with good upstream gear.
