Hahaha! I can't imagine discussing the finer points of optimization on here.

"the electromagnetic signal of course rides half outside the wire in a world increasingly filled with RF/EMF noise. Be sure to keep your cables off the floor or there WILL be impedence changes. Also, the Frequency Response is largely not relevant as 95+% of audiophiles don't have effective bass traps or ways to remove excess energy from the room. Intelligibility is the better metric, and no one uses it because it requires bass trapping and that's just to ugly and expensive."

Are you ready to rip my head off yet for all these largely unknown but completely true scientific facts? :)

Of course science would also require a blind perception test ...

When talking about high-end audio it is more of The Science™ than about the scientific method. The former is also far more profitable so it is not surprising to find so little of the latter in this field.
