sure it will work with any tube preamp.
I have auditioned Pass with vintage Marantz 7 tube preamp and it sounded great.
I am doing this with a ARC Ref 3 pre and Pass XA160. The one thing I am a little concerned with is the impedance matching. The Pass amps have a lowish input impedance which may not be a good match for the high (relative to ss pres) output impedance of tube pres. I cant say I am disappointed with the results though I do have some concern and need to investigate this more.
I don't personally own a Pass amp but I did hear the x250 paired with a Hovland preamp and it sounded great
