Tubes and Paradigm?

No experience with Paradigm, but Stereophile website has a few reviews on the Paradigm Studio series and from what I gather, the Paradigm is an easy speaker to drive which would seem to indicate that a tube amp would be compatible with these speakers.

For what it is worth I used to have Studio 60s and while I did not have tube amps at that time I see no reason not to give it a go. I drive Tyler Acoustic Linbrook System 2s and Taylo 7Us with 55wpc, and 50 wpc tube integrateds and there's more than enough power and the music sounds wonderful

They sound great to me.
I had the Studio 40 before getting the Signature 4.
Both sound great with my Jolida 502B.

I had Paradigm Monitor 11 V3 which I drove with a Prima Luna Prologue 2 with very good results except there was a lack of bass. When I switched to Cary 300B mono-blocks & SLP98P everything got even better including the bass. I also drove them with an ASL 2A3 integrated which was very sweet sounding although not the most dynamic or authoritative in the bass region. In other words don't be afraid to try them with different tube amps. Paradigm makes a lot better speaker than they're given credit for, I keep hearing folks say they're only for home theater.

Heard Cary 300B with ProAcs and it was a wonderful sound...I can't quite afford such a setup now but just upgraded my amp from Parasound to Sonic Frontiers Power 1 driving my old Paradigm Studio 20.

My impression is that Paradigms are great speakers (esp considering the price). If I won't find a good deal on ProaAcs here soon - I am surely upgrading to Paradigm Reference Series.
What I surely hear now is that they match well with tube amp but don't sound as deep (bass is somehow weaker and not as tight) as when driven by more powerful solid state amp.
