Fisher 400 tube receiver, Amber Black Series 70 (early model), Adcom 545 (inadvertant downgrade - I read too many reviews!), Bryston 2B, Forte 4a, Conrad Johnson 11a, Conrad Johnson Premier 12 monoblocks..
Then, after reading so many great reviews of integrated amps I decided to see how far I could down-grade and be happy. Close - these are excellent amps but not quite my resting point - were Magnum 208, Mistral LFD SE, Plinius 8200 II (VERY CLOSE).... Now I seem to be quite content with my Cary SLI-80 running in triode, although Tuesday my friend is bringing over his BelCanto SET40i ... we shall see.
BTW, preamps include early Amber and PS Audio models, 3 generations of Audible Illusions (great stuff!), CJ 17LS (wonderful!), and then, ohhhh, and then, I tried the First Sound Deluxe (whatever that $4000 model is called). WOW.
If I do go back to separates it will be to use the First Sound to drive damn near anything.....
