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?

Here is what thew add says:

All the new SAMAs (Stand Alone Motor Assembly) are supplied with an IEC detachable power cord. And while this makes installation in tight-quarters less of a challenge it has one other advantage: it allows you to upgrade the power cord. We didn't think changing the AC Cord feeding the turntable's motor would have much of an effect. That is until we tried the new VPI Super Power Cord. Improvements in background "blackness" and sweeter high frequencies were consistently noted during our listening sessions. For those using the SDS (Synchronous Drive System), the Super Power Cord will yield similar improvements over the stock cord.

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!
