Eric,
The one that I went to was the Accustic Arts DAC 1 Mk 3, and then upgraded to the Accustic Arts DAC 1 Mk 4. They're very good DACs.
I've since gone with the Wadia 581se CD Player driving just my power amp. That let me get rid of:
1. the CD Transport, power cord and digital cable.
2. the DAC
3. the Pre-amp, power cord and interconnect.
So all that I have now is:
1. the CD Player, power cord and interconnect
2. the Amp and power cord
It's a simple setup and it sounds great to me.
