Best Amp. stands

Barry,

At what frequencies do Corian, Granite,and Marble ring (or resonate)at? Does the frequency vary depending on the mass?

Are they frequencies that are of consequence in an amp stand?

How about Carbon Fibre shelving? Does it work better than the materials mentioned above?

Us hobbyists often see professional racks made out of these materials, and admittedly they sound pretty good most of the time. What materials should we be looking for?

Thank you in advance for sharing your expertise in vibration control products.

Consider the Auralex Gramma. Not glitzy but effective.

Flynntom,

I chose the cheep route 16" paver on the bottom 6 8x8x16 cinder blocks with a 16" paver on the top. I built 2 units due to the fact that I have 1 integrated, 2 amps and an av processor. I then built a 2 shelf stack out of 1-1/8" pine for each one. (impatience is what determined the pine). These stands will eventually go on points and I will choose a different shelf material. The cinder block/paver is rock solid short of pouring a concrete stand IMO the way to go unless you have to have the aesthetics.
