I don't want to open up anything that will lead to another group hug (after another breech), but a simple question here, especially for the no-difference crowd: What about THD? Receivers have different THD levels. Surely one can hear an appreciable difference when the THD gets up above 1%, as it does on some of the cheapest consumer-big-box and HTIB receivers. (None of which are regularly recommended on this forum.) I'm further willing to believe that your run-of-the-mill hifi enthusiast can detect subtle differences between a receiver with THD of .04% (say, Yamaha) and one at .08% (H/K). I haven't heard the difference, but that's because I've never done the blind (or even sighted) A/B test. But it hardly seems far-fetched to accept that there is a difference. I KNOW BEYOND A DOUBT that I can hear it above the 1% range, b/c I've brought home and returned some cheap-o receivers in my day. Features didn't account for the poor sound quality.
