Power Cords - Pixie Dust?

As an audiophile I am always prepared to believe that almost anything can make a difference in the sound. But this one makes me wonder. I have a TNT MKV with JMW 12.5 arm. The stand alone motor turns, via a belt, a flywheel that turns, via another belt, the platter.

I have seen an add claiming that replacing the power cord between the SDS speed controller and the stand alone motor can improved the sound of the table, "increasing upper range resolution and sweetness" or some such thing.

I suppose I can see how a new power cord might be argued to improve speed stability, but for the life of me how can a special power cord improve "resolution and sweetness", when the only function of the motor is to spin a belt, that turns a flywheel that spins another belt that turns the platter?? Does this claim make any sense?

Brucegel,

Thanks for the further information. I have one of those kits, too, but have yet to put it together. I'm quite anxious to hear it myself.

Well, I spent last night exchanging three diffreent power cords for between the VPI motor and SDS controller. I couldn't hear a bit of difference, even between a cheap standard cord and a $400 PS audio cable that I had purcharsed for my VPI ulimate outlet. Maybe my doubts that a power cord that has no electrical connection to the turntable could make a big difference colored my judgment, but I don't think so. In my view, in this application, PIXIE DUST!

so... some report no difference at all, while others report significant differences. Must be another one of those system-dependent & synergy-related issues? Can't help but wonder, why such contrasting variability?

Following questions re whether 10AWG junk is preferable to 12AWG GREAT wire like the 83802, I've just decided to double the stuff up to provide 9AWG DIY PC Kits! So that should quench those 10 gauge worry-warts, eh? Cheers.
