Definitely the Symposium Ultra Platform. I have the Ultra under my VPI Super Scoutmaster Reference rim-drive. I used to have a Gingko under my Super Scoutmaster before I upgraded to rimdrive and had to remove it. The Gingko had 2 separate platforms for the VPI- one for the table, and another for the motor. The platform under the turntable would move as it was supported by rubber balls, and cause the tonearm to wobble and shake when playing. Not a very well thought out product for this table. The Symposium Ultra improved performance and sound and eliminated shaking of the tonearm. This is a superior product IMO.
