What I like the best sound wise are Krell amps and Wilson Puppy's, I'm also a fan of the Macintosh tube amps.
My carver amps have served well up to this point. How I will feel about them after I upgrade the preamp and add the Martin Logans in the front is a good question. I believe they have the power to drive the ML's which is a good start.
the carver tm55 put out 500 watts per channel into 4 oms or 300 watts per channel into 4 oms
3/4 chanel amp I think is 60 watts per chanel
Thanks for all the input everyone - it's much appreciated
