I like the Cary SLI-80 idea if you could live with an integrated. Its a bit less than your totaal budget but don't let that turn you off. Its one sweet amp. McIntosh as well if you crank rock. The MA2275 can be had used in your price range.
Amps for Klipschorn speakers
I am in the market for a tube power amp and pre amp to use with my 1980s Klipschorn speakers. I will be using a turntable as well as a CD player. I am a musician and have a studio that is good size where this stereo will be located. I like to sometimes play fairly loud although what I am really looking for is quality of sound on this system. For a budget maybe $3-$5000 on each piece. Used amps are fine with me. I listen to rock, blues, pop, etc. Right now, I have an old 70s Marantz 250 power amp with a Marantz 3300 pre amp hooked up to the Klips. I am a musician and not an audiophile so I know very little about good stereo equipment but I want to take a big step up in sonic quality. I appreciate the help as I am ready to acquire the amps. Thanks...
