Black Diamond Racing Shelf for EMM CDSA?


I'm thinking of getting one of these for my EMM CDSA.
Would the 15x12 one be the right size? (Or would I need the wider one to have the feet fully fit on it?) The player is 17 inches wide.
I only see Musicdirect as the place to get it. (Any other places?)

Had anyone tried it for any usage? Any comments on it are welcome.

I hate using cones or balls or pointy things under my eqpt. because they seem unstable and make me nervous. The BDRS looks like it's just flat. Is this right?

Thanks in advance for your help.

'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.
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.

I live in So. Cal. and am concerned/paranoid with what an earthquake might do to the components on cones etc. in my audio racks.
