...when there aren't other factors clouding the judgment. See my comments bellow (taken from a previous post on AVS) and let me know if you agree or not.

I still don't undertand the mixed messages that are sent on these forums regarding amp power. On one hand, you often hear the reality that ijd said above: at very loud levels, your amp is only using 1-3 watts. On the other hand, you hear people saying that more power = better sound quality and imaging (especially with music). Break out your SPL and listen to music at 90db. I don't know about you, but I don't usually listen much louder than that, and I am generally more comforatable in the 80s for "loud" listening. So, what is it about headroom (that is almost never used) that makes a system sound better?
It's probably similar to the "all amps sound the same" argument, but if you compare apples to apples, the difference between a true 100watt amp and a true 200watt amp is probably only noticable at ear-bleeding levels, or in a cavernous room. If you are in a typical room with typical listening habits, my guess is that there may be a few seconds per week that might actually sound different - especially given the fact that your sub amp takes the most demanding job of low bass during movie passages!
The key here is "apples to apples" (amp to amp with adequate power supplies and the same pre/pro for example). I totally agree that a 200 watt separate amp sounds better than a 100 watt receiver, but the reasons for that are many. Just read any receiver vs. separates thread to see why. Am I completely off base here, or is extra "headroom" one of the more overrated priorities?
