As a retired Mac dealer, I had the priviege of having a pretty big "toy box" of Mac gear to play with. My current set up consists of C47/MC152. If you're able/willing to stretch the budget a tad for a good used piece, the MC352 will provide 3db more headroom which is quite audible during demanding passages. I've heard these 2 amps (and, others) in the same room with the same system and the MC352 is very special. But, don't feel like you're settling for 2nd best with the MC152. You'll get the "Mac sound" you're looking for in a smaller, lower cost, and more physcally manageable package.
