Metal, aluminum, or wood for a rack ?

Thanks so much Kenny.
I guess my question wasn't clear.
I really wanted to know if a metal that is magnetic would cause sonic problems over a non magnetic alloy when buying or building a rack.
I looked at your rack and it would be perfect. I just need a three shelf simple rack.
All the brass all thread I've researched is very expencive.
I can almost buy a $300 rack for the price of the brass all thread.
Maybe I'll have to bite the bullet and spend the yen to make a really sturdy rack.

Elizabeth.
You're freaking me out man.

Elizabeth, you can say it if you want to.
I get a kick reading behind your gender thoughts on male preception.

I've decided to build my rack out of wood. With stackable shelving with spikes at the bottom of eack leg that will sit on the shelf below it.

I'm going to glue two 3/4 in. balsa plywood together to make a 1 1/2 in. shelf.

I'll make a three shelf rack at 24 x 18 in. with all the hardware for less than $150.

I can't afford to pay $$$$ for a rack. The wife wont understand. So, I do what I can.

It'll be better than the 1/2 in. thick MDF that I have now.

Thanks to all that has contributed.

I just glued and screwed my two 3/4 in Birch plywood shelves together to make 1 1/2 in shelves and rapped on them with my knuckles and it was very impressive.

It sounded like you hit a concrete block.

No reverberation or resonance to speak of.
It's much better that the 1/2in MDF I'm using right now.

I'm also using Maple butcher blocks with cones between the shelves and the amp and CD player.

It's comming along just great.
When I'm done I'll put new photo's in my virtual system and update it.
Have a great day.

Oh.... +1 on the wood resonance.

I have finnished my rack. I'm so proud. It turned out beautiful. Very solid.

I looked at your system and was highly impressed.
