The Sondek has soft coil springs supporting a heavy alloy platter and its sub frame. As a result, it has really excellent isolation from floor vibrations.
So my bet is Mike is right.
Would be better if the tone arm, rigidly-coupled to the platter,

equally isolated. Cos otherwise any vibration etc with get to the
cartridge by that route.

The famous Sondek has the same arrangement.

And what about the drive magnetics ?

Electromagnetics could be used, it needs little power.
The opportunity to 'pre-order' says it all for me.

AFAIK it is intended that all sales be done on-line with the makers in Slovenia.

I say it's more complex than just magnets, otherwise someone would have produced one years ago. Besides, it'd be too unstable with just magnets.
Too much ripple in the DC would be sent to the platter, 120Hz. vibrations!
