I have found that MY rim drive works best with the turntable as solidly braced to the supporting table as possible. That means that there is to be NO movement at all under the table. That is why the use of Bearpaws rather than the mini-feet work for me. If any movement is under the turntable portion of the table, allowing the table to move at all, the out of roundness of the Super platter causes a rocking of the tonearm which is supported only on sharp point. The motor assembly therefore has to absorb the out of roundness and should be allowed to slightly rock, so the motor assembly should be on their soft rubber/spongy feet to do this. With the Super platter, if I put my finger between the motor assembly and the turntable itself, I can feel the motor assembly going slightly back and forth when working, opening and closing slightly the space between the motor assembly and the turntable. The Classic platter however, is manufactured more precisely, so that it doesn't move the turntable the way that the Super platter does. ....and an added bonus, it sounds much better too. I still have the Bearpaws securely holding fast the turntable, and the motor assembly able to rock if indeed there is any out of roundness at all. I can't feel it with the finger between the motor assembly/turntable test as described above, but even the very slightest error can rear its ugly head at the cartridge. My turntable setup is excellent now, (I'm using the Benz LPS) and find no reason to experiment further. For those who might want to know, the difference between the 9 inch Nordost wired arm and the 10.5 is so very minimal, I would think that aside from just wanting the 10.5, there really isn't a need for a change.
