All we can do is "guess" which one you'll like. Taste is so personal. I would guess the 7270 would be a noticable improvement because of the power and the autoformers. Anyway of trying it first? Good luck.
McIntosh MC162 vs. MC7270
I currently own the MC162 and enjoy it very much. I can pick up a MC7270 for a little less than what I could sell the MC162. Can anyone comment on the differences between the two? I know the 7270 has autoformers. I have a pair of Dynaudio 1.3SE's and while I feel the MC162 drives them okay I wonder if the extra power from the MC7270 would be an audible improvement. Thanks.
