I've been demoing a friend's this week. While I can see the appeal, I'm not sold on it. The "sterile" complaints certainly have merit, IMO. I really like the clean sound and the black background it provides, but on my HD600s, there's a lot of stuff that comes off sounding lifeless to me.
I want to demo the other similar-functioning units before I decide. Anyone know where I can do that with a MiniDAC, Mytek, Lavry, or Grace?
