While I buy into some stuff that makes ABX'ers go crazy, this isn't one. Around 1995 blind AB'd a $5k 5ft cord vs a $250 used (500 new), and a $20 Belden on a $75k system, and even the promoter of these could not tell them apart.
BTW, check out the path from the power generator, across cables, to the local distribution node, to your home/apt, then to the breaker box, through the building. Check for plugs out of phase, and rodent damage to the insulation, to the plug. And a "magik" piece of wire just knows how to cure any and all issues, and deliver 120 VAC dead on steady with no phase issues and no spikes - forever. That's one amazing item.
