No, you're absolutely correct.
When I got my FCC license, I thought I knew everything; working with scopes, frequency meters, etc. There was nothing I couldn't measure; and then I got into high end audio. That was when I discovered those dumb "audiophiles" who didn't even know ohm's law, could hear things that I couldn't measure.
First of all, an audiophile has very good hearing. Once upon a time I said if two amps measure the same, they sound the same; of course you know I was wrong, and so it is with harmonics, we can hear in between the rungs.
