The Soliloquy 5.3's do not like tubes in the power department. The preamp department will be fine with tubes but you have to have an amp that can control the woofers or bass. I read so many opinions of them sounding good with tubes. Not so! They were truly fat in the bottom end and bloated. The top end was rolled off no matter what tube amp I used under 50 watts. They sound better with good solid state. I had very good luck with a Odyssey Stratos power amp, Older PS Audio Elite integrated , Adcom 535 MkII, and Parasound ( I don't remember the model but it was 100 watts.) The Odyssey Stratos by Odyssey Audio was the best combination we got out of them. Be careful not to blow the woofers they are hard to find. They actually don't exist on the market. The gentleman I purchased mine from drove his with Rotel gear but I never heard it personally.
I suggest that you get as much power and quality that you can afford for them. There are some interesting hybrids with more power out there but you will pay through the nose for most of them. Good Luck
