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?

I second trying the slightly deflated tire tube (12" from Walmart) or the squash balls in cups. Both are puting you TT on AIR. This is where all front end componenets belong. IMO
Dear Listens2tubes,

I recommend trying first the balls and then putting butcher block or granite on top to see which sounds best. Mine sounded totally dead on top of my gel pads. I listened like that for a year thinking I really had it together. One day I thought why not try my unused butcher block. It was the difference between night and day. Which is preferable? Which ever sound works best for the owner. In my case I believed I needed a new turntable until I went to a rigid surface over an absorptive one. Now I'm thrilled.

Sincerely,
If your walls don't vibrate much, a wall shelf is the only thing recommended here that will work. Batters, like pole magnets, and springs all are the same and like hard and soft feet have resonant frequencies which may or may not help.
