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

This is a journey through real life experiences from you to everyone that cares to educate themselves. I must admit that I was not a believer in power cords and how they affect sound in your system. I from the camp that believed that the speaker provided 75% of the sound signature then your source then components but never the power cord. Until that magic day I along with another highly acclaimed AudioGoner who I will keep anatomist ran through a few cables in quite a few different systems and was "WOWED" at what I heard. That being said cable I know that I am not the only believer and that is why there are so many power cord/cable companies out there that range from $50 to 20-30 thousand dollars and above. So I like most of you have to scratch my head and ask where do I begin what brand and product and what should i really pay for it?

The purpose of this discussion to get some honest feed back on Price to Performance from you the end user to us here in the community.

Please fire away!

Single blind testing is used regularly where tester bias is deemed to have overall limited impact on the results.
What you’re saying is that your sighted test is better than other sighted tests. That’s just nonsense.

If you want to conduct a scientific test - of any sort - you need to eliminate as many potential sources of bias as possible. That’s a fundamental scientific principle, whether it suits your belief system or not.

What I am saying is that a blind test is not a sighted test and that it is the height of intellectual dishonesty to even claim that.

Anyone who has any experience running tests with subjective results has used single blind testing as well as double blind testing depending on the rigour required for the test and the potential bias of the tester. To say that a single blind test equates to a sited test is an ignorant position not based in facts, or born from experience.

So a double blind test is better than a single blind test? How about a blind test with just one eye open? Does it count as blind test? What if it’s sighted test but you really squint very hard to the point you are kinda unsighted and everything is very blurry? It should count as unsighted I believe. Or single blind. Basically if both eyes are closed, it double blind, if one eye is closed is single blind. And if you are squinting is 1/2 blind.

Another scenario is like when you cheat a little bit. Like you move the black clothe just a little that you can glance. How is that called?
