The Truth About Power Cords and there "Real" Price to Performance

Bravo to those who are starting to question the value of "high end" power cables to the quality of the sound that we hear as an end result.  There is simply no scientific or logical evidence to justify the expenditure of so much money for these units.

Good audio equipment is fitted with excellent  power supplies, which filter and stabilize during the rectification process to DC.  Power supply surges are a different story - but surge suppressors are the proper solution to protect our equipment from such damage.

Most of us are subject to budget limitations - and do not want to waste our hard earned money on "snake oil" solutions.  Science and logic should reign supreme in any technical endeavor - aside from the judgement of our ears - which can be overly subjective and misleading in some cases.  Let the buyer beware!

I was indeed expecting for you to say this about me (nothing new, the same arrogant, condescending, know-it-all behavior to be expected from you), but putting Micheal Lavorgna in the same meter? Really?

Here is another one if so inclined:

There are many different ways to skin a chicken, no?

If You claim that you can hear a difference on Your system, all I have to do is show that You cannot reliably detect the difference on Your system.

Perhaps. But to insist that you can base any assertion on the results of a single test or trial is simply absurd. That's why scientific tests rely on more than one test, more than one trial and - typically - more than one subject.

Of course, if you prefer to believe in certain things because of the results of a single test, that's perfectly fine. But in doing so you abandon any claim you may have to being scientific or objective.

You often hear people claim that as soon as a new cable was swapped the difference was "Immediately recognized", "Not at all subtle", "Could hear things never heard before" and "Transformed their system". So obviously they would have absolutely no problems picking between the two.............Right?

But the thing is I have never seen any reliable proof where someone can pick one over the other much over 50% when blinded. Going by the post here you would think that at least one superlistener can easily differentiate the cables at least 85% of the time in a blind listening test (and probably in a minute). Does anyone know of a reliable scientific test results where anyone could reliably tell the difference between anything costing over $50 (and I am not talking about using the throw away interconnects that come with lo-fi receivers or ultra thin gauge wires).

Here is your chance guys. Get some reliable witnesses and do a scientific blinded test. Show how you can instantly hear the slightest change in your cables. Then post it on all of the forums that it can be done. You will finally put to rest the countless arguments on this subject and prove to the world that expensive cables are better.  You would be famous!

You seem to be among the noisy minority here that places such faith in these tests, so please feel free to conduct your own blind listening tests and share the results here. Please be sure to tell us how the test was conducted.

Most audiophiles don't have much interest in such tests. After all, they're tedious, time consuming, and sometimes yield puzzling results. It's more fun to listen to music.
I've particpated in a few such DBTs. I'd never go to the trouble of actually organizing such a test, though. Provided that you truly want useful results, there's actually much more work to conducting such tests than meets the eye of the casual observer. And the results are useless if the test is not properly conducted.
