The studio where the mastering engineer who made the "Power Cord Test CDR" for me did their own double-blind experiments. They ended up putting home-brewed power cords on all their equipment.
The "recipe" is a dark secret, I am sure both for competitive reasons, and because they don't want incompetent DIYers burning their own houses down.

PS: Micha Shattner, a brave thinker if there ever was one, told me once that most audible problems in audio are mechanical in origin rather than electrical or electronic in origin. He believed that what was going on in power cords was mechanical resonances, from the electromagnetic force's making the power cord conductors jump.
George Cardas seems to believe the same thing about speaker cables; he specifies a loose braid for his conductors, so there is more self-damping for EMF induced mechanical motion. Further, he appears to believe that loudspeaker cable break-in is a matter of mechanical "settling" as much as it is the "forming" of the dialectric.
I myself think that that's why a true "Oliver Heaviside" solid-core coaxial cable for S/PDIF usually sounds better than AES/EBU.
