I can not comment on movies, as HT is a minor role in my way of life. However the statement that "the sonic differences between amps is relatively small if any", is completely dependent upon the quality and design of the amp. A Denon amp would be vastly outperformed in every conceivable way buy any number of amps. This is not a fair comparison based on price points, but a Krell, YBA, Levinson, SimAudio would be leagues ahead. I know I have always posted praising price point comparisons, but I also state that this is to be noted before comparisons. The Denon would be much better than a Jutan (remember Candle?) by comparisons sake, but not in terms of being held strictly to your statement.
Anyway, not trying to pick an arguement, just a little conjecture!
