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.
