I am using a Symposium Segue ISO under my Prime/Single Motor Flywheel/Peripheral Ring/Stillpoints record clamp with great effect and it is sitting on top of a 3" maple platform sitting on top of a Lead Balloon turntable stand. The Segue ISO comes with 5 special spring support feet that you will need to select the one for the weight of your table. Also use a Segue ISO under my VPI Scout upstairs on my headphone system sitting on top of a Pangea audio rack and again love what it brings to the TABLE. Enjoy the music.
TT on Symposium Super Segue - slate or maple underneath?
I've gotten a Super Segue for my VPI Avenger. I have various things on hand I can place under the Symposium. I wasn't sure if a 3" thick maple block would work better than a 1/2" thick piece of slate. The whole thing will be sitting on top of my wooden equipment rack. I know ideally I should try both to see what sounds better, but hauling a 70+ pound TT on and off shelves for listening tests (not to mention moving a 3" thick maple block around) can be a bit of a pain. I'm hoping someone here has had some experience with what they've felt works best under a Segue, so I could try that first.
