Power Cords


I currently have Wireworld Silver Electra power cords with upgraded Platinum plugs. I had two 1M Wireworld Platinum power cords, but rearranged my system and required longer cords. Yesterday I borrowed two Shunyata Sigma NR power cords. On the first note my wife softly said, "that sounds better". She said it was clearer. I listened for a couple hours, changing the power cords a couple of times. In my system and to my ears this is my conclusion:
The Sigma's are cleaner, definitely has more bass, a dead silent and completely black background. The Wireworld cords are more detailed, with a wider soundstage and better spacing/separation of instruments. All things considered I'll keep my Wireworld, but I'm curious to listen to other power cords.
After inserting the Sigma's I just don't understand how anyone that listened to different power cords could conclude that they can't hear a difference. There is a difference, but like any other component the individual has to decide if the change is worth it. $6K for two power cords is relatively expensive. Expensive, but oddly maybe a good value? In my system there was a definite improvement with better bass impact and articulation. Would spending $6K or just changing amplifiers yield similar results? As with most components there are trade-offs...is there a power cord out there that has the benefits of the Sigma's and Wireworld Silver Electra's? If so, at what cost?

Innocent question. As Audioquest is an outspoken proponent of wire directionality one feels obliged to ask, does Audioquest ensure their power cords are constructed such that when they are plugged in the correct direction of the conductors is maintained? In other words do they track the directionality of the wires during the construction process, albeit stranded wires? They obviously do for speaker cables and interconnects.
Breaking News! This just in! I must be a Mind Reader! Audioquest controls wire directionality for its power cords. From the Audioquest Hurricane power cord web page:

"Dielectric-Bias System (DBS; US Pat #7,126,055): By creating a constant dielectric field for the cable’s primary capacitance field or dielectric, DBS assures extended bandwidth and more evenly filtered noise dissipation, eliminating the distortions and ringing that plague other cables even after years of use and so called “run-in time.” In addition, DBS assures that the RF Noise-Dissipation System works as linearly as possible.

Controlled for Correct Directionality: All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion."

Cheers

So, let me ask you. Do you have a good feel for how the color of the cable jacket affects the sound, since you seem to know all about this sort of thing?
It's refreshing to see at least one power cord manufacturer who is conscious of the directionality of wire in general and of the power cord specifically. The correct answer to my question regard g the best sounding color for the jacket of any Cable or Power Cord is ......white! 
Huh? They asked you not to write the details of the Hurricane power cord? That’s pretty funny since the details are provided on the Audioquest web page for the Hurricane. Don’t believe me?
