Rex,
It was asumed that most readers already knew what was meant by "miles of wiring" with regards to interconnected systems. My point was that the entire system was basically unshielded and suseptical to all kinds of radio and atmospheric bombardment. Granted, your final step-down transformer isolates you from most of it, but there's still the lines between it and your breaker box, and finally to each and every wall outlet. There is NO further isolation transformer after your breaker box, so anything that gets picked up along the way, gets dumped into each and every outlet. You adding a 3-6 foot "audiophile" cord at the wall outlet, can do absolutely nothing to improve upon the footage of non-audiophile "Romex" wiring within the sheetrock walls. What kind of magic do you think is taking place within the wall outlet? Each and every one of those three contacts heads right back to the breaker box, via unshielded non-audiophile wiring and breakers, right out to the stepdown transformer. No shielding, filtering, decoupling, isolation techniques, nothing. Explain to me how ANY 3-6 powercord technology can create some kind of magic between the outlet and equipment, with regards to the entire house wiring. Instead of placebo, get your hands on some quality test equipment which will prove my argument. And believe me, it's NOT just my opinion. Anyone with background in substantial electronics knows better as well.
