I own 2xMC2102's and they sound wonderful. 1xMC2102 just sounded nice, however the sound was transformed with the 2nd unit. I use them in parallel and they have plenty of grunt and control, coupled with nice tube warmth.
One guy I know who has heard 275's and 2102's says that 1 x 275 sounds better that 1 x MC2102, however 2xmc2102's are a lot better than 2x 275's. go figure. sounds reasonable as monoblock tube amps with 16 output tubes v 8 output tubes should sound better as the 16 output tubes will be crusining most of the time.
