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

I recently replaced the stock cord on my Fathom F112 with a 2 meter Wireword Aurora cord and was pleasantly surprised to hear a little further tautening of response. The sub shares an electrical circuit with my RCM Sensor phono preamp and I noticed an unexpected improvement in its sound as well. I suppose that might be explained if the cord's noise filtration reduced sub amp digital noise getting back into the electrical circuit.
Try an original Synergistic Research AC cord for your powered sub. They can be had for around $125 on the used market, and will provide you with lots of tight, powerful bass energy. No need to spend half a grand on an expensive AC cord for your sub, when you think of the frequency range that is important here.
Yep. Shunyata on my Art of Sound, Wireworld on my AAD and an Audio Magic XStream on my NSMT.
I am using Synergistic Research T-3's on my Depth subs I notice tighter bass with less overhang or echo. Yes better cables do make a difference.
