I agree with the Bryston B100SST recommendation but it is priced quite a bit more than the others. I also own a B60 and recently owned the Naim Nait 5i. The B100SST is in another league as far as soundstaging and tranparency. It is also musical as heck, you can really follow the music. Simply the best sounding integrated I have heard. I'd try the Panache if you don't need remote.

Looking at B-60,5350,nait 5i, MF x-150...any thoughts on which one would work best with 4ohm load...looking for lively, transparent, detailed sound...thanks...
