I've got the maglev in my sota. If the table is totally level, the platter will spin dead silent and freely with the belt off. These are very precise installations and any deviations will ruin this. My platter actually floats and has a bit of spring when pushed down.
If you are getting any dragging or grinding sound I would first check for dirt and make sure the spindle is lubed. My platter did have the tiniest bit of noise when I first got it. A friend who is an engineer suggested cleaning the spindle and bearing, re-lubing and running for a couple hours. The noise went away and never came back. The factory hadn't put this through a break-in period before shipping.
