Best 3 channel amplifiers under $750?

I second the Anthem MCA30. Very neutral sounding with great punch and rhythm. On the warmish side maybe a B&K Reference 200.3.

Acurus A200x3 is also a very solid amp, very similar in tone/power as the Anthem MCA-30.

"Find yourself a used Parasound HCA-2003A. Or if you can up your budget a bit - an Aragon 8008X3. The older stuff is where it's at...."

And to add to that list, an Acurus A200x3. I currently have one in my main system and have owned and sold another of the 1st generation 200X3. Either are wonderful amps especially to anchor your front soundstage in your HT rig.
