Turntable Isolation

I have quad 22 l-2 speakers, NAD c-162 preamp, pair of Adcom gfa-555 amps, Cambridge Azur 640c cd player, Rega p3-24 turntable with TTSU and Herbie's mat.

Listen to all types of music, from classical to Sinatra to Miles Davis to early rock to Wilco to Arcade Fire, etc.

I've been looking at isolation solutions for my Rega (Gingko, etc) and decided to make something myself. I bought a piece of hardwood, cut it into two 19" x 16" pieces, drilled 5 dowel holes in the corners and the middle of one piece, placed Dunlop Sport (2 dot) squash balls in the dowel holes, placed the other piece of hardwood on top. Then, placed my Timbernation 2" thick maple turntable platform with spikes on top of the second piece of hardwood, then the Rega. Seems to work ok. My question is; how compressed should the balls be in order to get the best isolation for this "solution"?

I have a Rega P2 and even the slightest tap on the cabinet it sat on produced a thump through the speakers.
I cut some foam pieces to put between the feet and plinth. One kind of foam didn't do much. What did work well was to use two or more different densities of foam. Experimenting is the key.
Everyone probably has all kinds of scrap foam lying around. It may not be as elegant as exotic custom bases, but it works and is pretty much free.
