Some things are so deep into diminishing returns it's worth very little effort to worry about it. Contrast this with the considerable effort this guy is putting out, and it's as pointless as arguing about angels dancing on pinheads.

Hey! I got to use 'pinhead' in an interconnect discussion in a non-disparaging way! Is there an award for that?

Buy good UL approved wire, of suitable gauge for the run and load, and listen to some music.

YMMV.
