Granite and digital..


I'm thinking about making a homemade isolation platform for my cd player.What I was going to make whould be 2 slabs of 2 1/2" thick pieces of granite separated by a air bladder of some kind..There a lot of different isolation shells on the market but wasn't sure if granite is good for the over all sound.Any comments.

I think I might ask my friend to make me some maple stands.maybe put these on top of the granite with some sorbethan between them.I think I might do the same for the cd player but instead of using sorbethan maybee use a inter tube.
since granite has some ill effects on audio.I wonder why they use it with turntables?
Granite has quartz in it.....world average is about 70% silica.
In crystaline form it is piezo electric.

Possible explanation?
What about those new pico feet from audio advisor?I put a set under my player and then put the vibrapods there before on top of cabinet by tray with a little weight on top of them.For $25.excellent bang for the buck ratio.
My experience with granite has been that it works poorly on most front end components but can be wonderbar under some speakers, sandstone is even better and with less audible anomalies.
