Zikhmark, Thanks for your post and opinion of the various Mac amps you have owned. I had the 7200,7270 and MC-300 on a short list last year when I finally bought the MC-202 amp. I'm glad to have made the jump to the MC-402. It's interesting to note that of these 5 amps, in your opinion, the MC-402 came out on top. If I had bought the MC-252, I most likely would have loved it, but would have always wondered how much better the MC-402 would sound.
