I own one original MC-275 and use it for many years. I then bought two re-issued MC-275 in the 90's and run them in mono 150W per channel for my Ediolon. I recently bought another pair of MC-275 and put them aside for safe keeping. Simply put, it has the best output transformer which is so critical for tube amp. It is magical when it is run in mono mode. I have owned many other amps before and they include VTL Ichiban, AudioResearch VT-100, Jadis JA-500a monoblock etc.. The output transformers of these amps are nothing compare to the technology of McIntosh. For pure 150Watt per channel it is value for money.
Why do no audio enthusiasts use McIntosh?
With the exception of some of there tube gear, not many really use this stuff(or admit to it anyway), I am mainly referring to there amps. They look pleasant, they look good on paper and have the price of high end gear, but I seldom hear anyone claiming to like or one day dreaming of owning McIntosh. I have never really listened to there stuff, no good word of mouth sort of scares me away from it, the only people who like it are those who sell it, an uncanny coincidence? I don’t know. Sorry it this has been covered many times in the past, I ran a search and could not find anything.
