I used an ARC VT 130SE for almost 2 years. It worked well but I prefer solid state amps for my Cremonas. Recently I've used a ss TAD hibachi, and a ss Bel Canto in place of the ARC. The Cremonas sound very, very good with all 3, but bass response is definitely better with the transistors. Off my experience, I can happily recommend either of the above ss amps which are reasonably priced as well as terrific performers.
Good Luck
