Right now my m60s, vp150, and qs4s are running off a yamaha rx-v1400 receiver. I am considering getting the crown amp to run my m60s and I was wondering for a room thats about 12x11, is the amp worth it. The only reason I am considering this is because of the $120 rebate they have on the amp. Is the difference noticeable? In my experience a watt is a watt, as long as the amp is not clipping. Basically what i am asking is if you guys have made this change and recognized a noticeable difference.
