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?

Trick PC's for motors is simply a pure placebo product. However, if the TT has a PC akin to a $10 table lamp, I'd be inclined to look favorably on improved connectors.

Having used an Audience PC on a 20" Nokia 445Xpro monitor for a week for burn-in purposes, of course, I observed a moderate increase in brightness only, which I found most interesting.

Jackcob, could you please cite the location of the particular ad you mentioned?
Re: The ad... Curious; VPI's WebSite doesn't, AFAIK, list the product. Acoustic Sounds subtley implies it's a VPI product. E-mailed both parties for further info. Seems to me, IMHO, that it would be in VPI's best interest to supply the best pc required for the task with it's SAMA. The original SAMA came with a 3-conductor #18AWG hardwired SJT cord; (junior hard service, thermoplastic insulation.)

Considering the mass of VPI platters, I remain highly skeptical that a PC change over a stock SAMA cord would be earth shattering. I *have changed the plug on the stock original SAMA...yawn. Audio memory tells me that actually the SAMA change out was, well, subtle at best. For every system there's an opinion. For every change, there's usually a difference. Not all differences are improvements. Funny how the change/difference seems to vanish after awhile... Upgrades are the lifeblood of the software industry, and the audio industry is no different. Put it out there and someone will buy it. It's been that way since new and improved laundry detergent was invented.

I'm not saying this is impossible, but, IMHO, it has some heavy odds stacked against it. No way will I drop $300 for an experiment. That money would go a long way in the used record shop; but then, some are more interested in hardware and changes than actually collecting music to listen to.

Unaware that Forum rules only allowed posting the results of subjective field tests, which of course, result in individual opinions and observations, and that ideas and thoughts were disallowed; even with liberal sprinkling of IMO/IMHO's, which I neglected... And *that won't happen again.
Expanding a bit- VPI reported that the PC is built by them in-house, has a lifetime warranty, and even was a bit appologetic about the $300 price, claiming a high labor burden for assembly. Seems to be a *very low-profile VPI product...

My initial knee-jerk, untested skepticism was engendered by the fact that I do wires, motors, instrumentation, and power distribution design on daily basis for 30 yrs now, and the thought of a 5 ft power feed to fractional HP motor driving a huge rotating weight (read:flywheel), could have much effect beyond the 'ol classic wow & flutter, pegged-out my Skept-O-Meter. Maybe, but I get a Subtle If Any change, here.

BB- Please keep everything as-is, and just drop in the SDS. I'd be curious on your experience, since it's on my list.
