anyone use a Symposium platform under a turntable?

I use the Ultra Platform under all my turntables. It is important to notice that you need to direct couple the plinth with the platform witch is acting as a subplinth. Never use rubber or sorbotane feet. Rollerblocks work well with VPI.

Use SYPOSIUM ULTRA Stelth Great bass wonderful imaging sounstage etc table is TW ACUSTIC AC1 With Black Night Power supply feet and VTA Armboard. Wonderful setup!!

For my Nottingham Space Deck (no suspension) I use a Solid Steel stand with a Symposium Svelte shelf on the mdf shelf, then Symposium Roller Block Jrs, then Nottingham plinth and table. The Roller Block Jrs seem to add almost as much improvement as the Svelte shelf. Tighter, cleaner, quicker sound, keeping the slight Nottingham warmth.
