I think you'll probably have to pay a bit more for five channels for anything but Emotiva, or go used. Outlaw is generally considered a notch above Emotiva in construction quality and there are plenty of other, higher-priced amps above that (Parasound. Bryston, sky's the limit). Emotiva seems to be a value leader.
Disclaimer: I am a satisfied Emotiva owner.
