Srwooten, do you think the system would be better off with a Pass Labs pre rather than the BAT?
Yes. Pass amps and pre's are both QUIET, highly detailed, powerful, and accurate. If you like that kind of sound this is a great way to go. That is the way I went, although I ultimately sold my Pass X-600 monos and went with a Edge 10.1nl stereo amp. The big Pass monos put out way to much heat for my room.
You'll get a bit of tube warmth (enough IMO) with the Cary CD player.
The BAT gear is notably more colored. Nothing wrong with that.... If you like that kinda' sound go that way, but with a more "like-minded" amp.
Get a Mint Protractor to get the most out of your TT set-up. What are you going to use for a phono stage?
