Have a look at this thread :-
But personally to me if I had that budget I'd personally look at the WA7 or HP-A4. I had the HP-A8 for about 9 months and although it was nice, I felt it wasn't exciting enough for me. Granted the issue I had with it was more the amp than the DAC of the HP-A8.
Thanks for the suggestions. For some reason, I would have never suspected the WA7. It has good synergy with the TH900 I imagine?
Well, I think I have found a very likely DAC in the Ressonessence Concerto, now I just need to settle on an amp in the $1,000 range. A few in mind:
Woo Audio WA7
Any other suggestions to look into?
