power cords


do they make a big impact on video? say for a dvd player or plasma dsiplay...

Save your money! If you don't have much electronics background, ask someone who does. Ask them how a 3 or 6 foot powercord can possibly make a difference with regards to your wall's Romex wiring, lines to the power transformer, miles upon miles of KV lines routed through switching yards, and onto the generating stations. Where's all the tech wiring there? Don't buy into the placebo snake-oil. If unsure, obtain several "free" cords and visually test their results yourself. There's NO difference!
Where's all the shielded wiring back to the generating plant? The final 3-6 feet of so called "audiophile" cabling (including shielded) will have absolutely NO effect on RFI and EMI filtering that's already in the electrical path. Any seasoned electronics techs or electricians willing to jump in and explain this to our readers?

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.


Classic defense! There is science behind everything that happens, for which you've yet to explain how these so-called hi-tech cables perform. Common sense says you're wrong. I can't even begin to speculate on the amount of blind panel testing done where so-called "seasoned" audiophiles fail to tell the differences. I'm sure psychology majors have a clinical term for this kind of blind belief.
