In reply to:

so then what are the power amps for really. big rooms or to listen at high volumes or both.


Peace of mind. That's what they're for. If you think that your current equipment isn't doing the job right, it's amazing what looking at more expensive or additional equipment can do to your listening pleasure. All the sudden, problems that weren't there before seem to materialize...

I've been in the "inferioirity hole" before, but with some well-reasoned thought and a better understanding of how amplifiers work (thanks to this site and Google), I realized more power was completely unnecessary in my situation. My sitution is small room (12x13x8), very efficient speakers (M22s), and a powered subwoofer (SVS PB12-ISD).

Your situation is likely different than mine. Do what you think is right and you'll be happy. 2x6 is perhaps the best example of this on the forum -- and that's not a jab, either.
