Turntable upgraded power supply vs. PS Power Plant

You can't use that regenerated power with a turntable, PS Audio explains why.

The older P-500 made by PS Audio allows you to use it with a turntable. You must run it in SINE mode, which is a preselected run mode. I use to use it with my turntable and it does yield reults ...........

I am interested in the Premier but didn't know there is a problem with it powering a turntable. There is a review in positive-feedback that describes the improvement when the Premier was feeding a VPI Scout turntable. I couldn't find any reference on the PS Audio site - can anyone help explain further?

Is there perhaps a distinction between whether a Power Plant works well with an AC-powered turntable vs a DC-powered turntable? The Gyro is a DC-powered turntable, but the VPI Scout is AC-powered.

I have seen recommendations by PS Audio to use their Power Plants with turntables in place of dedicated power supplies...but they aren't the most neutral of sources.

Is there anybody who's tried this, with either or both of the 500 and the Premier, and compared it to a dedicated turntable power supply?

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.
