One other issue I am facing with the bigger Kuzma table is physical isolation. The Kuzma Reference is pretty good on its own, given that it has a suspension. The XL does not, and unfortunately, my listening room, for now, is at the top of the house, and has a wooden floor. I could go the route of a heavy duty stand- eg Finite Elemente makes one perfect for the XL- but i'm still not sure if it is set up on a wooden floor -covered by wall to wall no less (yeah, I know, but the house has been an ongoing project and you'd be impressed with what we've done so far- the original rooms date to 1790).
So, what if I put a massive piece of granite on the floor, and then mounted a heavy duty stand with isolating stuff on top of that foundation?
