Which preamp for a pass labs?

Neither?

Conrad Johnson.

Sorry, I find the entire current Pass line as way too flat and colorless. If you are going with an amp, I might strongly encourage you to look elsewhere for a pre, unless you were a big fan of the old AR house sound, in which case Pass or old AR makes sense.

Best,

E

mizioa you are most welcome and glad I could help.

Nothing wrong with an XP10, but I've compared it with others and found it expensive for what it is.  I also like the LS25 MkII,  In Solid State you might look at a T+A Elektroakustik,  used they will fall in the price range of the others. 

I have a Pass XP-20 preamp, which I consider the finest preamp have ever owned. That includes a CJ Premier 17LS2. I owned an XP-10 for a while and I thought it was quite good- and the XP20 is better. 

We are a dealer for Pass and we had the chance to audition the new XP12 
it Utilizes trickle down technology taken from the flagship XS  pre-amplifier 
It is a very open and warm extremely transparent preamp please contact me as I can discuss this with you further
