I also commented about this in the PS1000 appreciation thread, but I ended up with the following gear:
DAC: Audio-gd NFB1.32 (I wanted a balanced set up, it supports high end USB transfer rates, and the Sabre DAC chip)
AMP: Bryston BHA-1 (I wanted a balanced amp with great power)
I've only had this setup for about a week and I must say that it is amazing. I've been finding some 24/96 source music, like the new Muse album, and I find myself stopping work to listen to song parts as they come on. Definitely a recommended set up.
