I won't go back and read this article again, but all of the blind test articles always seem to miss the point of distinction I notice - clarity, smoothness (fill in the blank) at the upper edge of the volume range. In other words, I don't notice that my amp is better. I notice that at 100db a certain passage lacks a shrill point on a particular word or musical segment that my AVR adds at that volume. If turned down to the safe zone of both amps, yes, no real difference.
But that does not mean there is no difference in my actual use - i.e., my chase for recreation of the live event, with all its peaks.
One more vote for the Pixie Dust.
