if you can find a way to listen to the MC275, i would do that. years ago i was auditioning audio research amps - the dealer played equivalent AR SS then AR VT100 amp, and the VT 100 tube amp killed it. was night and day! same speakers, source, cables. - tube amp sound was so much more real, in the room presence. in comparison, the SS $3000.00 was almost unlistenable. the MC275 is a freak of nature! built like a tank/last forever/sound that rivals both mega watt tubes and single end triodes at the same time. even more control than some ss amps. however, many audiophiles value an analytical detailed presentationÂ… thats ok. but if you gonna spend that cashÂ… be sure would not prefer the tubes. personally, once i had a taste of tubes, i could never imagine seeking out a SS amp again.
