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.
Granite sucks, as in sucks the life right out of the music. The results are an overdamped bass region and a midrange that tends to be harsh and glare, especially noticeable on piano notes. I have a thick granite slab I've tried with many different components and the results are consistent.
Like rhljazz, my experience with granite is that it sucks when it comes to digital units. I've continue to use wood shelves but I have built and acoustical shield for th fron of the unit so the energy flying around the room does not get to the unit.
Thanks for the reply...My mono blocks are on granite slabs.Do any of you guys think that this could be a cause of my current bass issues I have talked about in my other threads?The amps are very heavy but wasn't sure if granite can have an effect on the amps as well.
Yes, electronics are surprisingly sensitive to the surfaces they sit on.
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 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.
