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

It is as it is....Wolfy! Audio is all about looking and thinking further. Nothing is as it is. The need to do things better as they are, gives higher endresults. Hearing is believing. And that is why quality sells at the end. And yes it is that simple!

I have class D amps which are fast but I have grown tired of the bass. It just seems too fast and taut especially for low bass. I like the mosfet sound for the very low bass in the REL subs. The mosfet just seems like the right speed for the low bass. I don’t think I would like your subs crossed at 140 Hz as it sounds like what I already had.
The reason why I can use this is cause of the way I use Audyssey Pro. I measure it at totally different places and hights compared to Audyssey. The end results are stunning. It gives what I call Stealth integration. Without it I also cannot use it this far. ( to be honnest) It gave me the quality I Always dreamed of.
Statements like "it is at it is...nothing is as it is" simply isn't much besides gibberish. Risking signal degradation or alteration by using digital room correction to limit and compress sub signals weirdly adjusted up into low midrange frequency levels (that will clearly interfere with any wide frequency range main speaker) is odd, and I can only assume this silliness absolutely MUST have digital room correction to work at all. Room correction gizmos are generally designed more to detect and limit the specific frequencies that produce standing waves or what a particular listener feels is unnatural or "lumpy" bass, and not necessarily to repair woofer abuse (!). RELs aren't designed for lower mids as they know that it doesn't make sense, and BO's "set it up weird and fix it with Audyssey" approach likely has far more impact on tonality than AC cables. I suppose the resulting overkill sounds like music to him, but my sympathies lie with anybody walking into his shop and his dream world inspired by what he thinks violins sound like. The rest of us can listen to properly set up subs (with fat AC cables) that add the mojo to their rig without risking the likely pitfalls promoted by a delusional self important salesman.
