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!

I have for the last year been using a LTA MZ2 and it sounds superb. I have coming a Supratek DHT/6SN7 to replace the MZ2. The XA25 to my ears sounds even more magical with a DHT pre. of course it`s my personal opinion.
Looks like I’m gonna give a Rogue Audio RP5 a go for round one here. I can source one locally, plus it has a phono stage, which is interesting to me. See if the phono stage can come anywhere close to my Herron.  I should have it in the next day or two. Keep the recommendations coming!
I asked a similar question.  Recommendations i got and researched.  Tubes4hifi, Don Sachs,  Supratek, Modwright, Schiit, Aric.  Still thinking....
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
