Linear Power Supply?

Can someone tell me exactly what an LPS supposedly does to improve the operation of a turntable motor? Does it run more precisely at a given speed? Does it vibrate less? I have a SOTA Eclipse motor with Condor and Roadrunner. SOTA is coming out with an LPS option which they say is better than the SMPS wall wart, but I want to know exactly how it’s better. If less noise in my system is the benefit, then I believe I already have that addressed because I plug it into my PS Audio P20 power regenerator.

I also have a Condor/Roadrunner. To get it more precise, level the plinth and platter better, and lube the bearing. I usually get 0.04 on Analog Magik or 0.02 on WFGUI by doing so on my VPI.

FWIW, the older Phoenix Eagle/Roadrunner used a LPS similar to the one SOTA has developed. Same case, even. The only difference between the Phoenix LPS and the SOTA LPS is that the latter has connections for both boxes.

Also, when I had the Eagle/Roadrunner, I had to separately ground the LPS. YMMV.
