Pass Labs Preamps with tube amps?

Have an XP-32 and it is excellent.  My friend had an XP22 but I always felt, although a bit more dynamic, it was lacking in naturalness and palpability.  Thx XP32 is in a different category form everything under it.  He ended up selling his 22 for a Coda pre.  He seems happy with that for now.  

Thanks everyone... I've decided to stick to my original plan and get a good tube preamp, and then hookup my SET amps, and get a Pass XA25 for solid state. 

I chose the McIntosh C22 MKIV for couple reasons, mainly: 
* has a tubed MM/MC phono stage (I play vinyl about 30% of time so the C22 should be 'good enough' especially with a tube roll). 
* has tone controls and loudness - I listen alot at lower volumes and it is nice to bump something a tad if I need to. 
 

The name is on it but Nelson does not design his preamps. They are an afterthought for him.

I have both a great tube preamp and a Pass-Labs XP-22 preamp and I love both. I also have a great 300-B SET amplifier and three terrific flea-watt class-A solid-state amplifiers that I use with both preamps. When I first got the XP-22 preamp, I didn’t enjoy the sound as much as the tube preamp, however that soon diminished as the XP-22 broke in. I enjoy both preamps and also enjoy my tube and solid-state amps all of which have their specific sonic nuances. The XP-22 works very well with my SET tube amp. Very articulate and sonically well balanced. And Pass-Labs products are known for their high reliability. While Nelson isn’t the primary design engineer for the preamps, his cohort Wayne Colbern is the designer, and I wouldn’t expect that Nelson would not be involved in releasing any of Waynes preamp designs without extensive listening by Nelson. I like my XP-22 so much that I got an XP-12 for my daughter two years ago for her birthday,
