I'm very late to the party, but wanted to mention, in case anybody ever reads this thread again, that, at present, my favourite full-range amp for my Tannoy System 215 DMT II speakers is the MC2 Audio S1400 (775/1400/1650 Wpc @ 8/4/2 ohms). The S1400 and its little brother, the S800, MC2 makes specifically for monitoring and mastering applications, not for sound reinforcement. They're the only two current MC2 models that use linear power supplies—all the sound reinforcement models now use switching power supplies.
But, apart from any technical details, I prefer the S1400 (around $3500) to the Bryston 7B SST2 monoblocks ($10K/pr
.), the Perreaux Model 750 monoblocks ($15K/pr
.), the McCormack DNA-500 ($6K?), and the MC2 MC750, among others.
So far, I can only hear the fans when I'm changing a record or CD, never from the listening position, unlike the MC750, which has louder fans.
The S1400 somehow manages just the right balance of gut-wrenching power, especially in the lower frequencies, with clarity and delicacy. It's also curious that while the amp uses a humungous 4 kVA transformer, it's also got the smallest amount of power supply capacitance (16,500 uF/ch) I've encountered in any amplifier. Weird, yes, but I'm letting my ears rule on this one.
