Interesting, but it would be surprising if it really was better than a similarly priced and well engineered conventional table.
Whatever vibrations would be transferred from the plinth in a conventional table, may be damped, but if the plinth vibrates, so do the magnets, and so does the levitation field, albeit damped. Ditto for motor variations, rumble, etc. Still gonna be transferred, but attenuated for sure.
Whatever airborne vibrations exist in the room should be exacerbated by the lack of a method of "sinking" the vibrations to a larger mass object, such as the plinth.
Gotta make sense that new issues arise with a floating platter: wobble and susceptibility to air currents. What happens when a window is opened, or a door slammed?
In addition, tonearm and cartridge selection is limited, and I bet VTA adjustment is a real treat!
Sorry, for all the "cool" factor, the old adage applies: just because you CAN do a thing, doesn't mean you SHOULD do that thing.
