Thanks everyone. I'll just stay with my AMPS in th yamaha it doesn't seem that I would gain much in just going up an additional 100 watts. I really don't listen to music at loud levels I may increase it a bit for movies but not at the point that it distorts or clips. Again thanks for all your input. The only other reason I may want to go to the Outlaw AMPs if I get the urge to upgrade to the M80's. Im under the impression that my Yammy won't handle the 4 ohm load to well.
