The only reason I have a seperate amp is for 2 channel lisening. So once I went that route (money route) I went 5 channel. Will a hign end 5 channel amp, or 7 channel out perform a receiver in HT, yes, but not by a over whelming amount unless you get into a real ear critical high end discusion. Then you get into a new pre/pro addition, so look at about 8k to really do that right. I bought my amp 99% for real finite music detail. If i was looking at HT/movies only I would save the money, or spend it elsewere, have you seen some of the new HD projectors (LOL) just prioritize the funds on what's important for you, there is no absolute "right" answer.
