System pairing

I'd re-think the Pass/BAT combo. Two different animals IMO. Sure the will play together, but they both are going in a different direction scenically. What about a phono stage?

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?

regarding using a Pass pre, which of the models do you think would be the best pairing with the X250 or X350?

I use the X-1 and really love it. I have heard the newer models are even more refined. Anything Pass is REALLY good IMHO.
