Pass Labs Preamps with tube amps?

I see plenty of search results for tube preamps with pass amps, but curious who’s experienced pass preamps (XP-10, 12, 20, 22) feeding low watt tube amps. Specifically SET amps, but any tube experiences would help.

I will be setting up two amps to swap between. a low watt SET amp and a solid state. My main amp listening being SET tube amp.
