Hmmm... I have been playing around comparing gingko Cloud and Symposium Ultra a bit in my system using Microseiki/FR64s/Koetsu and VPI Classic 3/Dyna XV-1s . Microseiki is used with Symposium junior roller or spike feet on Linn Skeet and VPI Classic 3 with Bearpaw brass cones/Linn Skeet (BearPaw came with brass plate that have cork wood under it so I think that it would not work all that well with Symposium Ultra).
The result is quite consistant with both turntable. Gingko has lusher, fuller midrange, more on sweeter, warmer tone and somewhat softer sound. Symposium has excellent bass slam, speed, detail. However, I feel the midrange went a bit beyond neutral to lean, and somewhat dry presentation. Both give blacker background.
My Symposium Ultra is a bit too small for my TW but my guess would be that it would match better with my Reed 3Q but might be a bit too much of a good thing with Graham arm though.
