Anyone running a tube preamp with a Pass XA25?


I've got a Pass XA25 and an XP12, great combo, no issues. Having said that, I'm curious how a tube pre might play with an XA25? Anyone running a combo? Thoughts? Impressions? No need for balanced out, a line stage is what I need. Thanks all!

No experience with the XA25 but do have a XA30.5 in my system and it couples wonderfully with my Lamm LL2.1 Deluxe that will be offered here on Audiogon for sale this evening or tomorrow. Enjoy the music
Went through the same scenario, looking for a preamp for my XA25. I have a older model Supratek Sauvignon and a LTA MZ2. For my ears the LTA won hands down. I still have the Supratek and will experiment with some different tubes.
I used a CJ ET5 and am now using a CJ ET7S2 with my XA25. The two mate very well. I also think you want the most neutral preamp you can find.
