Black Diamond Racing Shelf for EMM CDSA?

Rgs .. Right on . I've become unhappy with unstable things like springs , cones , balls , spikes ect . I have slowly started to go to solid turntable type platforms for all components with no lose in sound quality , in fact the bass has become firmer . Black Diamond is the product I found to be the best bang for the buck and one of the best sounding .
As far as your question , I would want a shelf at least as big as your component , the more mass the better too .
One of the above posters mentioned that the thicker shelfs are no longer available , I ordered one threw my local dealer about six months ago , that would suck I still need two more to complete the change over .

'a BDR Shelf is only ¾” thick, yet it is 25x less resonant than an 8” thick granite slab'? Better check your materials expert as the statement is not true. Yes, I am a materials scientist and know all the resonant properties of an 8" slab of granite, if you can find one.

ya' got to learn to do the "Samhar Snag". (that's how I got mine)

Just checked with BD , the thick shelfs are discontinued .
I thought I read that the shelfs were 25x less resonant than 8" of M.D.F.
If our materials scientist is still with us , is it true that sandstone is less resonant than granite ?

As long as we have a scientist here - If you are travelling in a car at the speed of light and turned your lights on, would they do anything? I always wanted to know the answer to that.
