Inescapable FACT: No one understands exactly how electricity works.
That’s why there’s so much Electrical THEORY.
People risk their lives on electrical theory, just as they do the theory of flight. I suspect you might mean 'hypothesis' rather than theory.
OK you got me, you win, 10ga OFC spools cable is just as good as SRs speaker cabling. I suppose you hooked it all up and did a side by side on two identical systems too? GIVE ME A BREAK, you did NOT. Second if you can’t hear the difference in a UP-OCC/teflon weave from your 10ga OFC spool wire. QUIT trying your hearing is SHOT.
My hearing certainly isn't what it was, but I hear differences easily enough. However my employees' hearing is much better and they couldn't hear any significant difference either; neither could the guy that lent us the cables! That might be different if the speakers were 4 Ohms but they are 16. That makes a big difference.
