Thanks for that link on the McCormack. Yes, I thought that the McCormack might have the best sound quality. I think at this point, you will need to decide what kind of sonic signature you want. The McCormack will have a very sweet and engaging sound. However, the Outlaw will still have more power supply and be able to hit the bass much harder - there would be a lot more impact and attack in the sound with the Outlaw (like "punch you in the chest" kind of sound).
On the Bryston, yeah some of their amps are heavy weights. The 9B ST you mentions only comes in at 59 lbs. (similar to Parasound). I heard a set of original Gen 1 7B monoblocks once. The sound was okay, but it was somewhat on the dull sounding side. I also heard a Gen 3 Bryston. I think it was a 2B SST model. It was definitely faster/brighter with a lot of detail and attack, but the amp just did not sound engaging. It did not reach out and grab you. I tended to lose interest. Some people love the Brystons.
I had an original Sunfire Cinema Grand 5-channel amp a long time ago. It was a significant step up when I was first getting into home theater. However, over time, I discovered it was somewhat sterile sounding. I upgraded to a B&K Reference 200.5, which was a HUGE improvement in sound - strength, detail and warmth. The amp just was really engaging and exciting. However, in the end, the B&K turned out to be too warm for my tastes, which caused me to move onto more neutral amplifiers.
