I used a PS Audio P300 to power the motor of a VPI Scout in the past. My experience is exactly summarized by Dkarmeli's post above. While it didn't provide the finer increments of frequency tuning the SDS did, it was good enough in my case. I heard no deleterious effects on preamp and cd player (also powered by the P300) by altering frequency 1-2 hz.
speed stability
Does anyone know if using a device like a PS Audio power regenerator accomplishes the same speed stability goal as using the VPI SDS controller? I have a VPI Classic turntable and run it, along with the rest of my audio components (except the power amp), through the P5 Power Plant. Since one of the goals of the P5 is to deliver a nearly perfect 120 volts, is an SDS superfluous?
Thanks!
Thanks!
