Well I got the Outlaw 7100 hooked up and turned the 4520 into a prepro, I must say the Power Amp is noticeably different, It is more Punchier , Cleaner and crisp! as far as power I would say this 100x7 is giving the internal amps 150 x9 a run for the Money! Im gonna leave it as a pre pro set up for now to get my ears used to it . I may look for a better 5 channel at least 125-150 Watts and drive my main 5 and use the Internals for the S Backs and Heights! Either way this 4520 Smokes my AV7005!

Its because the Outlaw is rated for all speakers driven at once. If I didn't have Emotiva amps I'd get myself an Outlaw.
The Outlaw amps are a fair bit more expensive than the Emotiva amps IIRC, so that would sway it for me, amps being amps an'all.
You guys are lucky to have the choice - you know, here in England, there is nothing that is remotely the equivalent of Emotiva or Outlaw (hence my importing my 4 Emo amps). Here, if you want big, powerful, external amps, you have to spend a fortune on 'audiophile' brands.
EDIT: I just checked - the Emotiva XPA-5 (5 x 200 watts) is $899. The Outlaw 7500 (5 x 200 watts) is $1,599.
