It almost sounds like you’re living with absolute certainty that we can’t trust any of our senses. How did we ever survive before measurements?
Your retorts are littered with appeals to authority and red herrings that have nothing to do with audio except that very exacting devices are needed to discern them at their extremes. Within those extremes lies the areas that we can hear and that’s where our ears come in: to choose what sounds best to us.
I have lots of old, basic cables that don’t transmit without audible distortions of sorts that I keep around for whenever I come across a new piece of gear. Once that gear has settled in to my satisfaction, I’ll break out the older cables to see how they effect the sound and sure enough, they do what they’ve always done: distort audible parts of the sound and back in go my reference cables. End of story.
All the best,
