Does the magnetic levitating platter make all other designs superfluous.No bearings!

Wait till you see the whites of its eyes or the levitation of the platter yourself.Oh and I almost forgot...listen to how it sounds.

Compared to what?

Geoffkait is correct.But this may be a hurdle less high to jump than previous designs.The question is how serious are they in perfecting this concept.Do they have the engineering chops to do it right.

audiophiles have had mag lev devices for twenty years. It’s not really a question of engineering chops. It’s that mag lev has insurmountable problems that makes it uncompetitive with better approaches. LIGO does not use mag lev for any of it’s isolation stages. And they know their isolation. Therefore, I’m out. Looking on the positive side, magnetic sensors are used effectively for active isolation servo mechanisms.

And do all this in a light tight and evacuated enclosure with no air, after all, microturbulences and micro temperature fluctuations will impact speed precision.

Funny,. I was just reading this desciption of the top VPI table, which included this ...

"The bottom bearing is an oil bath, the PEEK thrust disc on the bottom bearing takes the full 30 pounds total of both platters. We tried levitating the drive platter with opposing ring magnets for less wear but the low end deteriorated as you took off weight. Sorry other table makers, get a set of JBL Everest's and you will hear it too!! Bass requires a good solid footing."
