FWIW, I had a MC-352 for some time driving Legacy Focus 20/20s. These Legacy speakers are very efficient, but love current, and have impedance dips below two ohms. The MC-352 was NOT lacking in the bottom end at all. At one time [just before owning the MAC] I was using 1200 Watt Monoblocs, and the 350 Watts/channel from the MC-352 was stronger/better in every way beyond a shadow of a doubt. Therefore, I would not worry about the Mac's ability to deliver bottom end. However, Mac does have a certain "sound" to it. You need to listen to see if it is right for you.
McIntosh vs. Accuphase
I've heard more than once that Accuphase was Japan's McIntosh and was wondering if someone that has had experience with both brands would like to give their opinions on any differences and likeness these makes share sonically from top to bottom? More specifically the McIntosh MC252, MC352 amps vs like wattage Accuphase units. I've noticed in the specs of both that the Accuphase amps have a much higher damping factor vs. the McIntosh which from what I understand could tell how it might effect bass performance with a given speaker. Any input or stories you might have pertaining to either brand would be greatly appreciated. Thanks! Brian/Texas
