Turntable upgraded power supply vs. PS Power Plant


I've been considering whether I'm better off with a PS Audio Power Plant (either the P500 or the newer Premier), or the dedicated HR power supply for my Gyro SE.

I would presume that the HR is better matched to the Gyro, but would a Power Plant on the whole system give better results than an HR just for the Gyro? Has anybody done this comparison, be it with the HR or with another TT manufacturer's upgraded power supply vs. a 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?
