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

Audyssey EQ and Volume are parts of the whole system. I can improve the articulation of voices dramaticly. Even when we compare very expensive pre-amps word endings and breathing of singers is not that clear. Hearing is believing, so we compare all the time. Clients Always can choose what they want. We try to get the best quality possible. That is why I sell and choose only those products which are superior to others. I can sell everything I want, but I only interested in the best. This makes competition to other shops so easy.

Cables are a different part of audio. But for me one of the most fun parts. Cause of the thousends of testst I did with cabels I know how much you can positivly influence the overwhole sound.

You need to understand all the different properties/qualities every single tool ( amps, speakers, sources, cables, conditioners etc.) has. Then you can get the max out of them.
The important difference between Bo's world and mine is the fact that I don't claim to have the answers or deem the sound of my dusty old REL sub to be superior to anybody elses rig...I simply state that my system reproduces recorded music very well in my listening room, without the aid, expense, or need for extra signal processing. Others may relish the sound of Bo's approach and delight in the use of room correction, but many simply don't care about it...this hurts Bo's feelings but, alas, his issues with the need for relentless campaigning for support of his approach is best left to his therapist. You don't need to understand every tool, especially a tool like Bo.
Audio is just about the best quality in sound. Quality is something what people hear and understand very well when you do it right. It is about the joyment and happiness it can give to people. At the end it is about emotion and music as pure as it gets. That is the main focus.
I try not to use any equalizing or Auddysey as it takes away the dynamics in the system. That's just my opinion.
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.
