Hi Lewm...hard to put it in words. If you are familiar with the CA Innovation, you know when you put downward force on the platter, the platter goes down a bit, then pops back up when you remove the downward force, hence the platter magnetic floating concept I alluded to. With the Master, the CMB is sealed so I could not see it. There is a rigid shaft that holds the upper magentic patter to the delrin record platter. It's a rigid connection. Some how that shaft that rigidly couples to upper mag platter with the record platter is supported by the magnetic bearing, hence the float. When I put downward force on the record platter, the upper mag platter also moves down, but not far enough to make physical contact with the lower acrylic drive platter that has the belt on it.
Interesting that the Clearaudio site still has no info or mention of the Master Innovation.
