Well I've worked in 1 av store and 5 high end av stores over the last 10 years. And I still have yet to find a better value in both sonics and "cash outlay" than the Outlaw 100 watt x 7 amp! It's a killer deal all around.
While I have yet to see ATI's amp you're refering to, I can say that those ATI's are pretty clean, clear, and extended from my past experkiences. STill, for like $700 new, you can't go wrong as a first 7 channel amp with the outlaw!..it's no loose situation there, indeed.
