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!

Is it biases or biasi? When I look at very expensive equipment or speakers I don’t expect to hear great sound. Quite the opposite. I’m very skeptical that they will sound as good as they look or cost. Is that the bias you’re referring to? By the way, I’m frequently rewarded by being right.

There is too much scientific and controlled double blind study talk here (and I am a scientist).  This should be simple.   Show me some validated examples where someone can reliably pick between 2 cables costing over $50 (blinded, when someone else changes them) and they didn't know which one was playing.

Thats all.  Double blind, single blind, AB, ABX, Good change, bad change, Anything!  It could even be on their personal system in their home.   And to make it easy lets say they can notice a difference  over 85% of the time for 10 tries.  Not 2 out of 3.   And not barely over 50% for 10.
There should be dozens if not thousands of these examples on the internet.  How about at least one?  It should be easy to find. All of the people who invested big bucks on their Uber-expensive bragging rights cables should be referencing it all of the time. 

For some reason I can not find ANY examples.

"...over 85% of the time for 10 tries."
I guess it will have to be 90%. 85% might be eight correct and one "hmmm, I am not sure, may be this or may be that".

Wow! What a coincidence! That’s the same requirements The Amazing Randi uses for his Million Dollar Challenge! I had no idea his blind testing protocol was so scientifically correct. Color me impressed!

I was just being nice.......I guess Randi was being nice too. If I had a million dollars on the line it would be 99%.
Edit:  just realized you cant get to 85% correct in ten tries!  My bad.
