Parasound vs. Sunfire vs. Outlaw?

[BluElite]

Hey guys,

Question: Being that these amps are relatively in the same price range, which do you think rates best in performance and sound quality? I've heard really good things about the Parasound Halo A-51 but those have been countered a bit with the Sunfire TGA-7401 and the Outlaw 7900. Out of these three models, who comes out victorious? I believe the Parasound is the most expensive, followed by the Sunfire, and finally the Outlaw. But the Sunfire outputs more watts per channel; and how about "clean" power? I have a 7.2 setup to drive despite the fact that the Parasound is only 5 channels. If it's the best in the group then an additional 2 channel may be in the cards. My focus is quality. Any input would be greatly appreciated! Thanks in advance.
