Will power cables improve a VPI Classic 3 tt?

This question has been asked numerous times (on this and other forums) with regard to VPI and other tables. I'd say 80% of the respondents (myself included) hear no difference or strongly believe that it can't make a difference. Invariably, there are always the 20% who insist against all odds and reason that a power cord can influence the speed regulation of a motor or speed controller.

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.
