Power Cables diminishing returns

The problem with this question is that sometimes a $500 PC is twice as good as a $1000.00 one. I find that VH Audio AirSines are hard to beat in their price range, but they are not the right PC for every component. Buying used or going the Cable Company route can make a lot of sense, unless you find folks that have found a really good PC with your particular components.

Schubert---Bravo!! Well said above. The trick is always to discern when to invoke physics, when to recognize that physics is not quite up to the task of explaining, and when to recognize that one has entered the domain of metaphysics. You are not far from the kingdom of wisdom.

Guys (and Elizabeth). The problem is that the double blind testing did not occur in my living room with my power with my equipment and my music. These tests show that in a particular context, PC's are below the threshold where a difference can be discerned. These tests cannot prove that in no context can any person hear a discernable difference. Come to my house. I will switch out my 6K collection of PC's for the $600 collection they replaced. You can bring all the blindfolds you want. Then tell me you can't hear a difference.

I don't care if other people spend money on power cords or not. With all due respect, I get tired of other people telling me what I can or can't hear. I understand quite well the value of double blind testing and understand equally well the placebo effect. I am not a fool, and I don't throw money around foolishly, which is why I have 6K to put into a bunch of PC's that took my system and my enjoyment to a much higher level. How about I sell you all my $100 PC's, and we will both walk away happy?

Zd, Remember when the audio rags measured equipment, but provided no narrative on an actual audition? Perhaps I misunderstand, but it seems to me as if that is what is occurring here. I used to be in the camp of the skeptics. I did not see how PCs could make a difference provided that they made a solid connection at both ends and did not restrict current flow.
Then one day a friend loaned me 4 of his Vh audio AirSines while he was on vacation. I was just amazed at what those 4 PCs did for my system. One audition completely blew my preconceived notions out of the water. I subsequently bought 4 AirSines of my own, 2 VooDoo PCs, and one Audience E. In my system, the audience was a disappointment. I would never suggest the folks above who love audience cords are fools or can't hear. They found the right PCs for their system and I found the right PCs for mine.
I think the idea of drawing universal conclusions based on a single scenario test is fundamentally flawed. One negative result cannot prove a universal principle. One positive result also cannot prove a universal principle, but it does demonstrate that a potential exists.

Those who are certain that megabuck PCs are nothing but a $50 pile of junk marketed to rich simpletons might do well to remain quiet and explore that avenue as a sure fire get rich quick scheme. I wish them all the luck in the world.

Zd, I understood your position, and I am in substantial agreement with your post. I think maybe our positions differ a bit in that you are asking for particulars about the test, whereas I am suggesting that such a test is fundamentally flawed. It is always difficult, if not impossible, to build a meaningful case on negative information. This is why guilt can be reasonably proven, but innocence cannot. My reaction to your post was not a reaction against it.

Not to paint the anti PC camp with too broad a brush, but recently here and in Audio Asylum there has been a bit of mocking of the pro-PC camp, to the point of impugning the integrity of some well regarded manufacturers without having any direct experience with their products. Its fine to have opinions. Its not so good to insult other people with them.

Schubert, I work for one of the largest pharma companies. We don't see a dime of taxpayer cash. If we benefit from university research, we pay big bucks. The numbers quoted above for the cost of bringing a drug to market are accurate, and the research is funded by cash revenues generated by marketed drugs. Most university research is not aimed at discovery on new drugs. There are a few drugs on the market that were discovered by universities, but I can assure you, they are not dropped in the laps of pharma for free. Most pharma companies are working hard to bring down the cost of drug research.
