[quote author="JohnRoberts"]+1 for multi-tone IMD, I like the real world aspect of in band stimulus and in band distortion artifacts.
The power of Sam's effort is that he has applied a common or standardized test criteria across so many devices, so we can compare apples to apples. These discussions don't diminish that effort.[/quote]
Indeed not; his work is nothing short of magnificent. I suggest only that adding a HF IM test to the battery could exercise high-frequency distortion mechanisms in a way that provides remarkably graphic results. I'd add that these test have the advantage that they are doable with a simple, relatively cheap setup -- a competent sound card that will do full duplex recording and a DAW program with a spectrum analyzer option.
Peace,
Paul
