I'm certain that I could tell the difference between .02% and .005%. I could tell you if it's higher or lower order, and I could tell you the phase as well if it's the low order type. Phase is irrelevant beyond 4th order. I spent most of a year voicing my amp for my speakers, trying this and trying that, and I definitely know what different kinds and amounts of distortion sound like.
