Do you run a high end power cord on your sub?


I have a Rel B2 sub in my system, and have never really bothered with a decent power cord for it. I have an "Iron Lung Jellyfish" power cord, which is better than a stock cord. It is a $30 cord but is actually suprisingly good when you are just "testing the waters" of what power cords can do. I am considering something better, but not sure if this is the best place to spend money? What are your experiences with upgraded power cords for subwoofers? I am thinking about an Audience Powerchord e, as I use Audience power cords on my other components.

Other components in my system:
Thor Audio TA-1000 mk II preamp
BAT VK-55SE amp
Hyperion HPS-938 speakers
PS Audio PWD mk 2
Audience AR6T power conditioner and power cords
Nordost Heimdall IC's
Anticables speaker cables

My friend and I have Audioquest NRG-5 power cables on our REL subs. I have 2 REL Stentors III and he has 2 REL Studio III subs. The Audioquest NRG-5 power cables sound very good and seem to be cheap if you can find them. I am not sure how they compare to all the above but they seem to work fine and sound good.
We compared the Kimber PK10 gold, Audioquest NRG-2, 4, 10 and Wild and the Purist aqueous with a subwoofer. The kimber was very good for the money even beat the NRG-10. The Purist beat them all with ease. Even compared to the Wild it was still beter. More control, better timing. I sell a lot expensive loudspeakercable and interlinks from Audioquest. I asked Audioquest to make soon better powercables. They said they are now developing better ones. I am ready to test.....
Get'em Bo1972!, I am reading what you say here, I got a little laugh here, Seems nobody has acknowledged you, I enjoy your opinions, keep it coming, sooner or later, someone will say something to you, cheers.
Audioquest is now busy to develop new powercabels. I think they are tired about my comments that there powercables are not good enough. I Always say: It is as it is. So keep it simple!
I can say with near certainty that Audioquest likely does not care one teeny bit what Bo thinks about anything. To think there is much, if any, performance disparity between well designed high end AC cables connected to subs is laughable, and displays a strange support of some arcane supposed perception of quality based on sales experience and live violins. There, I said something.
