Which preamp- Pass Labs X1 vs Cary SLP2002

I'm moving 2 channel music away from my HT pre/proc, and I think I've narrowed down my preamp choices to the above, but I am unable to demo, as I am in a rural area.
Associated equipment-
Pass Labs X350 amplifier
Arcam FMJ23 CDP
Proac Response 2.5 spkrs.

I like my Pass amplification, and think there may be something to 'synergy' design from a single manufacturer (and the avail deals on the old style X1's are tempting), but I've also heard thet Proacs 'love tubes'....

Any help in decision making would be appreciated.
Thanks!
