Granite vs Wood DIY Audio Racks?

I recently upgraded my CDP which requires a bit more room than my current rack has to offer. While there are quite a few new racks I like, I find them to be a bit pricey so I figured I'd give DIY a shot.

The materials I'd like to use are either John Boos maple cutting boards (stained black) or granite slabs (black) which I can aquire at a local marble shop. While I prefer the granite looks wise, I rather choose the material which would sound better. Supports would be 1" threaded rod. Does anyone know where I can get 1" female threaded cones for the rods?

My listening room is on the 2nd floor and has an oak wood floor.

I appreciate any thoughts or recommendations.

Regards,
Steve

If you want one inch female threaded cones try member esoler. Outstanding work.

Steve, drop me an email if you'd care to know more about my techniques but suffice to say I used pretty common tools to build my rack. Truth be told I experimented and posted my findings, and have since built other racks, but I think Slip took the concept to the next level.

On the top shelf I did not use washers. I drilled about 1/2" down with a one inch drill bit, then the rest of the way with a 5/8" bit. Rather than use the standard 5/8" #11 plain old nuts on the top, I used the locking type (with a nylon insert). I tightened them til they locked, then used the nut underneath the top shelf (that does have a washer) to crank it and pull the locking nut into the 1" recessed hole. Hope this explanation makes sense...

Steve,
Believe it or not, the best prices I found were at a Williams-Sonoma retail store. They have all sorts of sizes. I got 24" x 18" x 1 1/2" at 62.00/shelf.

Get a hold of Jahaira. He uses a DIY rack with granite, marine plywood and rubber/cork/rubber mats under the granite. I've seen his rack and consider it way superior to most aftermarket products.
