Will power cables improve a VPI Classic 3 tt?

I agreed with Photon totally. Unless you have AC current problem in your area, defected motor or bad cable.
I also experiment with different cable to my VPI Aries 2 Extend with no success.

I use a Shunyata Diamondback Platinum ac cable on my Scout ONLY because I had one hanging around and wasn't being used. Since my entire system is wired with Shunyata including two Hydra Power Conditioners, I figured what the heck. I too hear no difference.

Forgot to mention that I had asked Otto Hanak at Acoustic Signature turntables about this a few years ago. He was amused at the idea that a power cord could affect speed stability and assured me that no performance benefit was to be had with upgraded power cords in that specific application.

Thanks to all for your responses. Seems that the consensus is no improvement when it comes to using an upgraded power on a turntable. Again, thanks!

Never noticed any difference myself either
