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?

Yes, it does make sense. The better that motor does its job, the better the sound will be.

I power my motor directly from a battery, and that was a big improvement. Then I just got a Signature motor upgrade, which added high quality caps and resistors to the motor assembly, and the sound got even better.

Don't ask me why it does this, because I can't really give you "specifications" that would technically explain it. I could guess that miniscule variations in speed are reduced, and creates more fluid presentation. But I can tell you that it does sound better, and that's good enough for me.
