Turntable isolation


I have my TT (Rega P7) on top of my audio cabinet. The cabinet is an Ethan Allen Townhouse component cabinet with a marble top. I noticed this weekend that when I touch the doors to my audio equipment I can hear a light thump via the cartridge. Even when I lightly tap the door the sound travels through the cabinet woodwork, through the marble to the cartridge. How can I isolate the TT from the rest of the cabinet?

Squash balls (or maybe raquet balls) in suishi type cups (Ikea maybe). Poor mans Gingko that works.
Hello,

A butcher block on top of gel mouse pads. Total isolation on a ROCK solid platform.

Sincerely,
I'm thinking about doing the same thing with my Thoerens TD125.

I just called a local granite counter top dealer and they said they can sell me a 24" x 24" x 2" piece of granite for about $35. Anyone see any issues?

I know in the manufacturing world they use granite slabs lifted by air, water, oil, etc to get truely flat and vibration free surfaces.
