Dave,
I recently built a sandbox type of rack for all my components. Picture this, if you can. 2 stands side by side. Each stand has 3 levels and is about 36" high. Each level is a 4" high sandbox containing about 50lbs of sand. These are made of MDF and painted gloss black. They are held together as a rack with 3" wide x 1" thick baltic birch posts (I actually bought a table top from Ikea and cut it into posts). Cones on the bottom of each post anchor them to the concrete basement floor. I use 3/4" baltic birch cutting boards from Ikea as the shelf placed on the sand. The wood is all finished using tung oil. Very striking and very heavy and inert.
However, my unsuspended turntable showed a marked thump when I knuckled the stand itself. I still needed some kind of isolation. I wound up using another 3/4" birsh shelf with some large diameter bubble wrap under it. This worked significantly better than many other types of isolation that I tried (rollerblocks, sorbothane, pucks and such). It's almost dead silent to the knuckle test now.
Please let me know if you come up with something that isolates better under the shelf.
Enjoy,
Bob
