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

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.
OK guys. Finally finished it w/ some Boos blocks. Actually more than an hour ago, but I wanted to listen to some music. I love it. It seems to me I'm getting a bit more detail and defintion. Where as before it was a bit muddy. I'm gonna post some pics under virtual systems.

THANK YOU ALL for your advice and input.

I also picked up some smaller Boos for the amps. Once I cone them I should be done at least for a couple of days :)

Thanks again.

Best Regards,
Steve
I apologize for jumping into this thread this late, but I remember a thread a few weeks ago where a lot of the regulars here chimed in with their opinions on pine being the superior material for audio shelving.

Anyone want to tackle this issue?

I intend on pushing forward with some racks in the late summer/fall and would like to hear what people think.
Trelja, I remember that thread. I think they were talking about laminated pine. Nrchy had posted to the thread. Maybe he will chime in. The ideas and opinions were pretty positive about it. Nate?
