Granite surface plate


Does anyone have any experience using a granite surface plate as a turntable stand? I'm considering getting a 18" x 24" x 3" granite surface plate and stand to be used for a turntable stand.

I had also read that a thick maple cutting board on a granite surface plate works very well. But I can't remember where I read it or if the credibility of the commenter.
Surprise some of u don't like granite platform . As I understd it HRS used granite for their platform as well except they added the " rubberised footers " . So the question is not whether granite is good . It's the implementation of the platform . Likewise there are a lot of opinions about merit of acrylic & glass platform & some manufacturers do used them eg Grand Prix Monaco , Mana rack etc
Audio blazer, don't forget that HRS uses a 0.75" granite platform set in a aluminum shell and sitting on a polymer bed and supported by load specific feet. The surface plate being discussed is 4 times the mass of the HRS.

Granite is useful for isolation, but IMHO, granite needs to be damped to prevent ringing etc.
It will ring like a bell and give you a bright treble balance .Try Symposium its neutral and will give better stage ,bass,midrange etc.
Bpoletti,
I would suggest that you call Adona. I am sure that they would sell you one of their granite shelves. They are the best of both worlds. They bond granite to a layer of MDF with a special (proprietary?) polymer. Anyway, it eliminates problems with ringing etc. Visit the Adona website. I have been using one of their racks for abourt 4 years and like it very much.
