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?

Thanks! for the update- ricred1
I will second the Eryka Badu "live" disc to demo anyone's system.
Keep me posted as your try different cabling in your system.
Happy Thanksgiving!
Has anyone besides me tried Tempo Electric's custom power cords? I have a pair powering my McIntosh MC2301 amps, off a PS Audio P10, and another one from the wall to the P10. Absolute bliss in mine, and others ears, who have heard my system. Of course, the power cable, and other cable rat race, can be an elusive venture for many, and for many years. The specific Tempo Electric cables I own are The Big Twist Custom silver over copper with Furutech Fi-50 Rhodium AC connectors. I have experimented with Shunyata, still have some on sources, Black Mamba, and HMS cables as well. It is really time consuming, and costly to keep experimenting. I am happy where I am at right now with all cables. I think my record player and preamp are still stock cables, but they are plugged into a P5, and the P5 is plugged into a Carbon wall outlet with Furutech GTX D Rhodium outlets. All backbone power is on 8 dedicated 20 amp circuits, with a Environmental Products EP 2000 Power filter. YMMV.

Finally, my vast and worldly listening experiences having lived in Europe for many years have shaped my specific listening parameters and have brought me to my current state of nirvana. Of course, experimenting in this hobby, is part of the hobby, just don't get caught up in the minutia that take away from the pleasure of being in the hobby in the first place. Enjoy the music while you still can, life is way too short. Have a good day.  
I wil write a review of the Hurricane this week. First it will got to Audioquest to be checked. It will not be negative at all.

2 weeks ago we compared it in an audiosystem of a friend of mine. We compared it with the AQ NRG-1000 and Purist Audio Aqueous 2008.

Mann this is a different world. A few years ago we compared the AQ Wild powercable against the same Purist Audio Aqueous 2008. The Purist was the clear winner that time.

But the Hurricane doens’t even take the Aqueous seriously. It laughs at it and asks if it needs to take this cable serious and as a real competitor.

I was already very surprised with the Hurricane. But now even more. I will write in details why it is that different and unique.

Even compared to the NRG-1000 the differences are rather huge. The NRG-1000 was my favorite AQ cable. The Hurricane is in a different league.
I just swapped out the WEL 20A cables on my monoblocks for the AQ Dragon HC, no comparison -- now the HC Dragon is twice the price of the low power Dragon, and four times the Hurricane -- sounds as if the Hurricane if it delivers half of what the Dragon does is a stone cold bargain

The Dragon HCs are so much more detailed and dynamic than the older WELs it's as if you have gotten a completely new amplifier
I’m sticking with my Wireworld power cords. I’m sure Audioquest power cords are fantastic, but way more money than I would allocate for a power cord. I’ve changed my interconnect cables from Wireworld Platinum to Audioquest Fire and love the results. I’m listening to speaker cables now and will choose between Audience AU24 SX and Clarus Crimson. After changing speaker cables I’m officially done changing equipment.
