LP12- Power Supply- Need education

I have read a lot about different options to upgrade the analogue power supply.
A phono stage need to amplify micro signal would require very good power supply to ensure there is minimal noise interfere with the signal.
I read about Lingo and other power supply articles, however they never mentioned about the science behind it.
How could a power supply powering a motor will introduce noise to the cartridge especially belt drive?
How do you measure the noise when playing a record?
Or would  the power supply provide a more stable rotational speed, my speed measurement on the turntable shows very consistence rpm once it is playing?
I really do not understand why a Lingo power supply cost so much but cannot provide an improvement with a measurable results.
Could someone educate me.

If you guys are interested in what Bill did you might was to look on the DIY site.  There are quite a few threads on 3 phase controllers there.  Bill helped a lot, to say the least.

If I am not mistaken,  he is using a 3 phase AC frequency generator with even more bell and whistles than what we built.  He is running a 3 phase DC motor on 3 phase AC.  What Lewn has is a single phase frequency falcon or eagle, which I use to have.  The only DC that is going on is in the name.

Bill is a sharp cookie. Glad to see Sota realize this.

Enjoy the ride
