Slate vs Granite vs Maple?

Generally I use Maple where I want to warm up a piece and Granite where I want to liven up a piece..I am sure there are exceptions to the rule but Maple-Solid State and Digital and Granite for tubes..Just my general rule...

I think wood is the way to go. Pretty stiff and yet still has great damping.

You might consider having the rack designed to accommodate after market shelves like the Symposium's.

Research "Corian" It's completely non-resonant in the audio/audible bandpass. It's available in a bunch of thicknesses and colors: (http://www2.dupont.com/Surfaces/en_US/products/corian/corian_use_gallery.html)

Hmm, interesting... so since I have tubes, the best bet is probably granite. Maybe I'll try the combination. Rodman, thanks for the link to Corian, but I was under the impression that total non-resonance isn't necessarily good for TTs? I heard phenomenal things about Neuance shelves... are they out of business? I'd love to get one but I never see any on AG. How does Symposium compare with the Neuance?
