I assume you are talking about the 2200's as they are the only monos? I've heard they are pretty potent little animals, at least when talking to my Outlaw forum gurus. They are a different design, not strictly A or A/B, but a A/B/G design. It will provide Class A/B power up to 80 watts (which covers about 98% of most listening situations). Above 80 watts the Model 2200 will instantly shift into Class G amplification. Some like this design, others don't, mostly this allowed them to have a smaller/stackable mono that puts out a lot of efficient power.
I have the 7700, and of all the external amps I've owned, so far it is my favorite, although I did like my Odyssey mono's as well.
