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 agree fully with the first two posters that I have also found granite as a base to sound forward and edgy in comparison to wood or polycarbonate. Granite can be beautiful to look at under electronics, but can have negative sonic effects. Maple seems to be an affordable, attractive and good sounding surface to rest things on.
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?
