CDP that Contains Slate


During my research for a new CDP I thought I read something about one or more that contained slate for the base. Does anyone know the brand? I thank you for your help.

I believe it may be Ancient Audio. If memory serves, the Polish reviewer Wojcech(?) Pacula uses one as his reference. I didn't bother to look any of this up so I am winging it.
Couldn’t one rest any CDP on a granite slab and achieve whatever perceived benefits that are being sought?
