I'm in the camp favoring wood, preferably maple. I can't think of anything worse (sonically) than glass, unless it's marble or granite.
Something to replace glass shelves....
I presently have 1/4 inch glass shelving under four of my 2 channel stereo/home theatre components on wall mounts. I want to put the glass back into my Bello Getti rack and replace it with cast acrylic or maybe carbon graphite. Carbon is very expensive and if I choose 5/16-1/2 inch cast acrylic the price is still pretty good. Even in black with polished edges. Can anyone help out which is better for vibration/resonant control and sound qualities. My components are a power conditioner, belt drive CD player, bluray player and pre processor. Any suggestions are appreciated. Thx in advance.
