“In most audio-grade shielded interconnects, as compared to standard coax, negative has its own internal conductor and the metal shield is attached to ground at only one end, thus defining the cable’s directionality.”
Actually that’s three lies. Firstly, standard coax is an audio-grade interconnect, it’s widely used by the big commercial music, broadcast and film dubbing studios for MADI. Second and far more important lie; the metal shield is NOT attached to ground at one end only in audio grade cables and consumers should NEVER attempt to do this. Quite a few musicians (and others) have died because of this and those who lifted the ground at one end charged with manslaughter!! And lastly, as they are attached both ends “thus [obviously NOT] defining the cable’s directionality”.
