Incidentally, many Clearuadio turntables have magnetically suspended platters - BUT it's a static magnetic field operating in exactly one axis (up/down), and with platter tightly constrained & stabilized by a traditional shaft bearing (ceramic shaft in sintered bronze sleeve). This works extremely well but STILL has a problem that the platter (no matter how massive) can move independently (up/down) relative the arm-board. Adding heavy ring clamping also alters the VTA, which is annoying. I say this as the owner of an Master Innovation.
The Mag-Lev concept is just complete nonsense, with a dangerous dynamic magnetic field that can never properly control or constrain the platter. The platter is perfectly free to move & wobble in ANY direction, and from videos it does this quite a bit.
