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

People who use poor old Rel subwoofers maybe will not hear any difference between different powercables. It can make a very big difference with new and good subwoofers. These days you can use subwoofers to much higher freq. ( like 140 hz, cause of the fast respons) this makes the integration so much better. The better powercables works better in the low freq. but also in the freq above 80 hz.
The person who is chief of Audioquest Europe has been 3 times to my house for listening. We talk often about Audioquest cables. We also spoke a few times about there powercables. He asked me to test a few. I gave him my opinion. I also told the same info to Bill Low last year wenn I met him.
Audioquest Europe arranged the new Wild Dog pure silver interconnect for me. One week ago Audioquest America had the parts ready for this new top model subwoofer cable. I will receive it soon. I will write a review about it as well.
I noticed an improvement in sound quality with upgraded PC's on my JL f113's while listening to 2 channel music. For HT (movie effects) I don't notice that much of a difference.
I don’t think a higher crossover is any help in a 2 channel system. My RELs are crossed at 22 Hz. Not being able to do a 140 Hz is of no concern to me and my system.
And by the way the poor old RELs seem to make pretty good music better than a lot of the new stuff out there. Most of the new stuff is too boomy for music.
