Closeout?
Was it a couple grand off?I wouldn't mind a new one myself.I have a vintage MC275. That Mc275 MK6 is of the best sounding amps made today..I would easily put it in the top five amps sonically.The GL KT88s in the Mc275 are a very complementary match.I was very surprised when Mcintosh didn't use the Genelex KT88 as original equipment on the reissues,being the Genelex was original equipment on the vintage amps.
Later it came to me and then I confirmed my theory and it was correct after talking to Mcintosh engineering.When the Mc275 was first reissued in the mid 90s,there was no Genelex reissue and the best KT88 at that time was supposedly the Svetlana wing C.They had a long standing contract with St Petersburg Svetlana to supply these tubes but now I think they will be using the Genelex.
The voltage amp and phase inverter in the Mcintosh amps are the most influential on the sound from my experience.
Honest amplification is better than excessive 2nd order distortion anytime.

Hi,Yes -- dealer moving out of McIntosh and had a few pieces left, including this MC275-VI new in box. I couldn't stop myself, fortunately.
Thanks for the tip on the GLs and input tubes. I'm going to let this cook for a week in order to get used to its sound as stock and then roll some of the tubes. I have the GL KT88s and can borrow Winged-C 6550s, and I have some NOS AX7s and AT7s somewhere.
It is an amazing-sounding amp. I've tried it with a few speakers and it works beautifully with all of them, including the little LS50s, which seem twice the size with the Mac. Very different from my Rogue and absolutely silent -- no tube noise, AC hum, nuttin.
Back to the music!
