The mc275 is slower, but I love it. Heck it is a tube amp! I could probably say that it is slow, rounded, yes, midrange beauty, yess, colored, maybe a little, and I think I am going to put another record on right now. An audiophile friend said that I am listening to more music than anyone else he knows.
I don't know which generation MC275 you have, but the current v3 has good bandwidth and risetime even by today's standards. The
Stereophile review and measurements indicate that its -3dB bandwidth point is 91Khz, and the rise times of its square wave responses correspond to that and are very precise and square. Given that, the treble rolloff you perceive may simply be its uncommon smoothness, and the reason you play so much music through it is because it conveys more of the sonic and emotional cues of live music including that transparent, seamless tube midrange combined with commendable speed, clarity, and frequency extension with no ringing, harshness, or overshoot.
It is a great amp for the money. That is very hard to argue.
It is a steal for the money, if you love music.
At about $4.5K new, indeed, what's not to like? If I had the coin I'd have one in a heartbeat.
