The earlier PS Audio Powerplant 300,500,1000,1200 had a selectable SIN setting and you could adjust the voltage in increments of 1. This LOCKED the AC output to a FIXED Voltage aka you could set it for 120volts and that's what you got.
The newer PS Audio Premier Powerplant is similar to the ExactPower in that it only regenerates the top distortion with Class D amplification so the unit supports more watts and runs a lot cooler... I was hugely dissappointed when I upgraded from a PS300 that wouldn't power my projector to a Premier by the fact that it can only correct power by about 5 volts and when my voltage flucuates from 122-129 the Premier can not be locked to 110 or 120 like the older Class A style regenerators. So my premier now switched from 120-126 on output and you can't lock it into a specific voltage. So this varying voltage would speed up and slow down the motor controller and be very bad for a turntable sound.
On a good note my PS Audio Premier runs my Video system (minus AMP and sub) including my projector which looks way better it still helps to protect the bulb. Noise floor was lowered, dynamics increased etc..
So if you buy an older PS Audio Powerplant 300 or 500 skip the Multiwave versions which cost more because you can't use those functions, only the SIN setting.
Clearaudio makes a Syncro turntable regenerator, VPI makes the SDS, and a couple others exist for turntables so you have other choices.
