The Bryston 9B-ST has gotten excellent reviews, including a "Class A" rating by Stereophile. I own the Bryston 4B-ST and 5B-ST amps, and based on my experience with them, I can recommend the 9B-ST very highly. The other "killer" 5-channel amp, if money is no object, is the Krell 1500, which has 300 watts x 5, and retails for $8500. For more info on the Krell 1500, see the current issue of "Home Theater" magazine.
BAT has the new VK6200. It's definitely Audiophile quality. Not cheap, but nothing is for better performing equipment!
