difference between ATC SCM7 and SCM12?

what is a good integrated amp to power the scm7's?

the 12's are a hole different league, they use the same driver as the 20's, what a great soundstage, incredible!!!!!! I use the 12's for my fronts, 7's for my rears. The 12's are give a much fuller soundstage! I run a carver 200x 5 amp and can't pull everything these speakers want though!

I went with the 7's because I felt the instruments simply sounded more accurate...I a/b-ed the 7's and 12's, although the 12's obviously had more behind them...it was the trade off.

Amp's anyone? Still thinking about the Creek integrated, Classe CAP 150, or the Primare I20...
