Power cords


Is there any truth to the following which, as you can tell from the quotation marks, is not my brainchild (my brain is childless...). I picked it up from the site of a well respected amplifier manufacturer and trust I am not committing some sort of legal or moral transgression by reproducing it here:
"When you plug your power cord into the wall outlet you are in 'SERIES' with all the wire on the other side of the wall all the way back to the power source. The small length of power cord from the wall to the amp is insignificant compared to the miles of wire it is connected to. As long as the power cord can deliver the current and voltage required to drive the amplifier to full power it is as good as it can get."

Well, I admit I have my own opinoins on some specific issues re equipment. But I think it's important that we do not gravitate into different camps based on objective v. subjective, or ears v measurements, as this is a false dichotomy and leads nowhere. Anyone in audio needs to use BOTH. Ears and measurements are both important. I do not know anyone who makes a decent speaker, for example, who does NOT tweak the final product by listening. On the other hand there is not a single speaker or cable maker who does not set down measured design parameters for the product. Every part of our systems was made by folk who measure and do math (egads !)too. Take a look at the simplest introductions on some subjects, Dickason on speakers or Rosenblit on tube circuit design, measurements are here to stay.

I think it's very hard sometimes to correlate what you hear with a specific measurment. That does not mean measurements are not important and that we should stop trying. On the other hand, its not so hard to look at the design specs of a cable and ask intelligent questions about the specs and to also ask how much it should cost to make cables based upon those specs. My primary beef about wire is the rediculous price put on it when its used for certain applications and the fantastic hype by the industry that can only exist if we think of wire as some miraculous mystery. The hype, and especially the price tag, cannot survive a sustained look at the design paramenters of cables. If you hear a difference in cables fine...there is no excuse for the cost.

Maybe we can all learn from Henry Kloss who died only a few days ago. I quote from his obituary

" Mr. Kloss was guided as much by his senses as by his intellect. Loudspeaker manufacturers tend to stress the technical specifications of their product, which is like describing a wine by its level of alcohol and tanin or a chocolate cake by its calorie content alone....Mr. Kloss developed formidable technical prowess but avoided marketing by the numbers. Instead, he strove to design equipment for the ear and not the spec sheet." NYTimes,2/2/02

Formidable technical prowess in service of the ear...maybe his greatest legacy?

Sincerely, I remain
Pbb: I can sympathize with your desire to stay away from what can seem like pointless arguments over irreconcilable differences. I would just remind you that you are not just writing to those who respond, but also to the (probably far more numerous) lurkers, a lot of them new to audiophilia. You do them a great service by expressing your skepticism about some of the more inventive claims made for this or that miracle product.

I really worry about the newbie who's told that, "if you can't hear the difference between a wood shelf and a glass shelf under your preamp, there's something wrong with your hearing." There's probably nothing wrong with his hearing, but he goes away discouraged.
I swore to myself that I would never again get involved in another PC discussion. listen to Garfish, Sugarbrie, and Bob bundus. These guys know what they are talking about.
3 cheers to these 3.
The general consensus is that power cords do make a difference (I have been convinced many times over). You may have several feet of Romex in series but...
The same can be said about the cheap appliance wire used in speakers and we all know that speaker cables make real improvements.
Being somewhat skeptical, I chose to make my own PCs AND dedicated lines at the same time from Belden 83802, which is 12AWG/2 with shield, using only FEP (Teflon) as insulation. So the 30-50 feet from my service panel is ONLY this stuff. At $2/ft it was easy to make a separate line for the CDP, pre, and two for the monos.
I must say I hear a difference. My already-dead-quiet system seems clearer, cleaner, maybe a bit more dynamic. No spectral shifts (fortunately). Differences in interconnects are now more readily discernible.
I might buy another 100 ft spool of this stuff if any of you want some for lines or cables. $2.50/ft if I do it.
I think there's somebody out there selling it for $3/ft.
100 ft spool sells for about $200 shipped.
I don't really buy this notion about 6 feet of PC "resonance" that has an effect on the system downstream.
Changing ALL of it to clean copper in Teflon inexpensively just seems like a simple semi-scientific no-brainer without all the high-priced alchemy. Cheers. Ernie
