Pre amp for Pass Labs XA30.5 – Tube or SS

I’m updating my system from the bottom up and have settled on the Pass Labs XA30.5 for power amp. The speakers are a pair of Harbeth C7-es3. Now I’m debating between getting a tube or solid state pre amp. Below are the ones I consider:

SS pre amps - Pass XP10, Ayre K-5xeMP

Tube pre amps – Audio Research Ref 3, LS27 used, LS 26, LS-17SE; Conrad Johnson ET-3, ET-3SE used, Premier 17; Leben pre amp.

Can you share your experience in any of these pre-amp with Pass Labs power amps? Any other SS or Tube pre amp that are worth exploring? Obviously, the Audio Research Ref 3 and LS 27 command a higher price.

I’m looking for a good synergy between pre-amp and power with correct output/input impedance matching. Music I listen include: vocal – both female and male, jazz, pop, chamber, symphony, etc. I’m looking for full-body mid, solid bass and extended treble, accurate sound stage, with a focus on vocal presentation.

Any suggestions are appreciated.

I'm using a Modwright LS36.5 with my XA30.5 and have enjoyed it greatly. I had the Modwright 9.0SE prior...something about that MW tube preamp sound that does it for me. Might be worth a listen if possible.

Charles,

I preferred my CJ (ART 2). I did tell Mark at Reno "If tubes ever start giving more trouble than their worth, I will just send you a check". Haven't heard the XP30 since it debuted but would imagine it could close the gap even more.

Agree with you, no guarantees. My rec was if he had to buy "deaf", as I so eloquently put it (thanks Czbbcl). It's just a comfort zone being from the same brand especially if that brand has Nelson Pass behind it.

I think most philes will end up with different brands. You have done extremely well with your same brand pair. It's not often a manufacturer makes a world class amp AND preamp. They seem to excel at one or the other even though they may make a decent attempt at the other.

RO817, to your last question:

My particular tube pres (CJ ARTs and ACT 2.2) seem to give me more harmonics and in their natural order than the different ss ones I've tried but the XP20 was certainly one of the better ones. Gather as much info as you can but it will eventually come down to your ears and preferences.

Onemug,
Your success with and preference for the CJ over the Pass line stage makes my simple point, at some point you just have to listen.
