Conrad Johnson--Best used Model


I just purchased a Pass Labs XA 30.5 & want to pair with a CJ preamp

I'm looking for experience on which model to by used or new for $1-3 k

I would love the Lush house sound with details and soundstage without being plodding

XP15 is a phono preamp. I would have to concur that there is a substantial positive benefit of running balanced outputs from a preamp to a Pass amp, and you can't do that with CJ.

Agree with oddiofyl about getting in touch with Spearit Sound. A first class group whose members have always provided helpful answers and advice following questions I've posed before and quite some time after I purchased my CJ Classic Sixty amp from them.
