The testing with a single tone is LESS SENSITIVE. It gives a lower percentage result, than the equivalent multi-toned IM test waveform like the one that Jon Risch uses. However, music IS multi-toned. Unfortunately, my thd meter that does a 90+dB pre-null of the single test tone, cannot null other tones at the same time. If someone will fund me, I will build a multi-toned pre-null box to null a series of spaced tones in front of my HP-3563. Then I can get even larger levels of distortion residuals. However, I am happy enough with differences between connecting wires at the moment.
Now for the rest of you out there. It is true that these levels are low, BUT they are consistent, and change with each type of wire tested. This is real, not guesswork. I am sure that they correlate to subjective listening response to some degree at least, because the 'lousy' wires usually measure much worse than the hi end wires that I have tested.

You have no hard data to back it up your assumption that signals that low are audible, but you express an opinion. That's fine.
And I have no issues with your ability to test signals that low in the "mud", re:real vs guesswork.
No, I just have my ears.
""No, I just have my ears.""And given your experience and status, I would listen to any opinion you would give concerning what you hear.
Technical issues... That's the easy stuff.
