The industrial sector pays plenty for well performing quality cables, of course the stress's are somewhat different from those found in domestic hifi, yet similar levels of electrical performance/Characteristics are employed by those that make for the hifi market,of course, the cables will be special, but are they needed or any better in regular domestic use than perhaps a so-called simple/standard quality cable, i would say it's negligible, but just in case i had bouts of Bat hearing without realizing, i got some high quality industrial cable from a chum who supplies it...cost was a few drinks, so even if bothered dont need to look for better.. :)
