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

In the past I sold Tact/Lyngdorf. There system I never liked. At the end you get less. In the beginning when I started with Audyssey I heard clear advantages, but also the limitation. After done 2 measurments with Audyssey ( there way) I started to do it differently. I had thoughts that could solve the limitations. And yess I created a much better level in dynamics and also in resolution. These days I can use Audyssey EQ and Volume so precise that I have more dynamics and resolution than without. I can let people hear the difference with my measurment and without it. Now with Audyssey Pro ( what is superior compared to xt-32 or below) I have more freedom. Compared to very expensive pre amps I can let people hear articulation of voices so much clearer. 2nd and 3 th voices are better separated then with many expensive highend pre amps. The same about decay and definition of instruments. What I do is let clients choose a number they know well and we compare them with there preamp and the Onkyo with pro. The difference is so big that you do not want to go back anymore. There it is; it is all about quality and all the details you can hear.
mmmm, pass the pop-corn please, I might miss something here, wolf_ Garcia, You are up for best comedian of audiogon, no offense, this is a compliment, you have had me laughing out of my chair!, when I said, sombody will acknolege you Bo1972, I did not know saying that would lead up to this, opps, sorry fellas.
Wolfy is definitely the clown ( we call it: Pipo overhere) of Audiogon!! To have your own opinion is fine with me and a good thing. Often he speaks for other people. He doesn't know me, please speak for yourself Pipo!!
Discovery has a programm called: Idiot abroard. They should make a programm with Wolfy called; Audio Idiot!!
I never claim to speak for anybody else, and, of course, only know Bo from his innane commentary punctuated by hysterical responses not limited to questionable claims of valid experience with live sound, strident misguided and elitist proselytizing regarding personal taste, and an utter lack of comprehensive critical understanding of anybody elses opinion. All characteristics of the tragically insecure. I do admit to attempting to have as much fun as possible at all times, especially with delusional gasbags like Bo, who instead of directly addressing what I (and perhaps others) might consider to be reasoned criticism of his absolutist single minded approach to selling hifi, gets going on weirdly personal tangents designed to denegrate the valid opinions of anybody questioning his approach. I might be viewed by Bo as a clown and idiot, but 40 plus years as a successful professional musician and sound technician has taught me at least one thing: suffer fools only if it's sort of fun, and enjoy the chance to possibly inspire them to dig their own hole in which to plunge. OK...maybe 2 things.
