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!

Dkarmell-

The SDS will drop the voltage to as low as possible to maintain the necessary speed and frequency (user controlled). It does have a minimum specification is always reached: 72volt, if the motor is working properly.

You can see the unit change upon start up from 115V to the 72 volts at 33 rpm. At 45 rpm the voltage is 83V as I recall.

The user has no control over voltage, just frequency - which is set to a strobe such as KAB's.
