Its interesting you mention this. I have my SAMA placed on a 6 x 6 slate tile and isolated from the maple platform using Sorbothane feet. I am also using silk thread belt for the Super Platter. The plinth rests on footer so both the SAMA and plinth are at the same relative height. I prefer this setup over having both the SAMA and plinth resting on the maple platform.
Rim Drive Mod or how to make it even better
I was going to just add this post to a previous post regarding the VPI rim drive, but this is important and I want all those who use the new drive to know this. I just spoke to Harry W who told me that if you use sorbothane, or soft felt, etc, under the feet of the motor/flywheel assembly, the sound is even more improved. Don't use it under the turntable itself...only under the motors. I tried it and it REALLY works.
