It is magnetically suspended. The vacuum will prevent
air currents from moving the plinth around. However,
the vacuum will also change the damping
of the cartridge somewhat,
Negligible if relevant, but the picture tells a different story. I recollect
that Scott's browser does not show pictures as easily as the ones most of us
use.
and I am not sure what it
will do to the record/stylus interface.
If you look at the picture, the plinth, the platter, the tone arm, and the
cartridge are out in the air. The evacuated chamber must be below the plinth
where we can't easily see it.

but if the magnets vibrate would not the change in flux
vector cause a vibration in the suspended object
George, you are so right. Magnetic suspension creates a force that varies,
depending on the distance between the magnet and the suspended object. If
the magnet moves closer to the object, then the force on the object
increases. Sort of like a spring.
Magnetic suspension's big advantage is reduced friction that would oppose
the rotation of the platter. It is used to create so-called 'frictionless"
bearings.
As a suspension that would resist or absorb vibration, magnetism shapes up
as just another combination of mass, spring, and damper.
