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"?

Where is your table in relation to your speakers? I am surprised I don't hear more about people placing their table in a separate room or equipment closet. At the very least one should look for a null in standing waves. All equipment remedies will help still further but the best location should be the starting place.

Hi Gmsasso,
Your set-up sound pretty good to me. I've had my table in a separate room in a sealed solid oak box lined with sound damping for years so I must admit I've never looked for a null in my room. With my set-up I can still faintly hear music with a stethoscope on the outside of the turntable box. I see a lot of pictures with a table only inches from the speakers. That can't be good. Blah, blah, blah, sorry I'm rambling.
I have a room analysis program "CARA" that is pretty cool in that is shows room nodes in a visual way that I find easy to "see". I would use something like that to find a null. As little as a foot or two can be significant. Good luck!
PS frequently the most significant impediment to optimal placement is significant other objections. Lucky for me we had a spare bedroom so the go ahead to get the "stereo crap" out of the living room was gladly given.
