best 5 channel amp for home theater

The only high end 5 channel amp I have heard is the Conrad Johnson MF-5600. I was very impressed.

Your budget is the criteria by which "best" must be based. Aragon/Acurus, Proceed, Krell, Rotel, etc. all different prices and different sonic impressions.

Class "A" amps limit this thread. Krell, Rotel, and Sunfire are not class "A". I personally think the Sunfire is one of the best buys, but it is not class "A". Unfortunately, I can't comment from experience on any true Class "A" products. But I would admonish you not to confuse a high price with high quality.

proceed hpa2 and hpa3, I know that is 2 amps but what the heck.

Stereophile Guide to Hometheater rates the Aragon 8008X3 as a class AAA amp. They now make a five channel version for 4000. The Bryston 9B st is rated class A in Stereophile. About half the power of the Aragon but I am sure they are very close in sound quality.
