The problem IMO is a completely solid support. Say you have the base solid on a solid stand. Any vibration just goes around and around. Nothing is dampening it.
I prefer a balace of mass AND dampening. Then the vibrations can't keep moving around. The dampening agent cuts them out of the system.
I also prefer haeavy mass for TT applications, but add in the mix some dampening product between the TT plus mass, and the Stand.
I use #10 Rubber bottle stoppers. They are just right for the task. My Kuzma Sugi S is on a 'teak' type wood 17" by 17" one inch thick, and that is on the 4X bottle stoppers on large 4X patio bricks on the stand. Th 17" by 17" has extra mass on the corners. All in all very stable, and solid, it does NOT ring, or allow vibrations to pass through.
Perhaps even just a very thin dampening material (sorbothane sheet) between the granite and the 401 would be an improvement?
(I am assuming you have SOME sort of issue now, Or you would just be a happy clam with the setup.)
