I have an MC275 MK VI amp and absolutely love it, sound is fantastic and it looks stunning/beautiful IMHO. I strongly suggest you get the problem resolved before giving up. I also have a C50 pre-amp/DAC that I had a firmware problem with, caused by me! McIntosh were absolutely superb helping me resolve the problem. I am fairly new to McIntosh, however, I understand their after sales support and general equipment reliability is second to none. Don't give up, enjoy the hobby/music.
McIntosh mc275
Received new MC275 yesterday. Units On/Off switch doesn't work. Amp only shuts off when you unplug it. And no, I don't have any triggers attached to it. Most disconcerting considering I waited three weeks for it. I've read Mcintosh has lowered the bar the last couple of years, but this is aggravating. Would not recommend this amp! Does anyone have any suggestions for another brand?
