Look at number 5 - the description of the Continuum Caliburn includes
this phrase:

"The turntable employs a magnetically levitated magnesium platter,
which is suspended in a vacuum to guarantee there are no vibrations."

Suspending in a vacuum sounds like a contradiction in terms. A vacuum
tends to draw things in. At some point the turntable has to be riding
on some kind of bearing - i.e. something solid has to be contacting
something solid - which AFAIK provides a potential conduit for
vibration transmission. From a theoretical standpoint, how would you
"suspend" something like this in a vacuum in a way that guarantees no
vibration?

And of course a vacuum requires a seal, which sounds like something
with the potential to fail.
