I too like Tireguy's suggestion for solid state. For tubes, I would highly recommend the Wolcott's (Albert's choice as well). I heard the Wolcott's on the Maggie's and do not know that I have ever heard the Maggie's sound better. I was SHOCKED!!! I have heard them with Krell's, Classe, ARC, etc and the Wolcott's did something none of the others could. It provided a really focused soundstage as well as suprisingly great dynamics and bass. If you are interested in the Wolcott's, call Duke at AudioKinesis, a great dealer and a great guy!
Good Luck!
