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


This could be a game changer but we will have to see if the high end mafia embraces it or dumps it into the east river after chopping it up into small pieces.Time will tell.

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."
I wonder how they keep the magnetic field that levitates the platter from interfering with the magnetic field in the cartridge?
