I had an MC275 VI with a C1100 and found the match really wonderful. The C1100 is dead quiet and cast a wonderful soundstage. If you have the budget, don't need the built-in DAC and have space for a two box setup, I highly recommend an audition.
McIntosh Guy Going Tubes? (Maybe?)
Need some thoughts, comments, advice: present system (mainly McIntosh): Wilson Sabrina’s, MC601 monos, C52 pre, MEN220 room cor, MB50 streamer, MCD80 spinner, PSAudio P10 regenerator. My thoughts are to go analog/tubes via MC275 MKVI monos with C2600 pre(and undefined TT). Pros - Cons?
