I doubt I've ever met an 'average' human', especially from the relevant subset that obsesses over music, or the sub-subset that obsesses over gear, but I do take your point. It's a very messy world, and people are funny.
I also wouldn't overlook that confirmation bias works both ways, that an average human Not expecting a difference could ignore, miss, minimize or deny a phenomenon that, given the necessary measurements, could be quantified, if only in a well-equipped lab.
If it were necessary to float our cables with helium, sacrifice 3 virgins and a bottle of Scotch to get our rock on, I'm sure we'd find a way.
Hmmmm, helium floated cables with no dielectric at all to mess with the signal, provide me a link to those!
