Ideal material for wall mounted TT shelf


I have a wall mounted shelf made of mdf with specially fabricated brass cantilevered supports(pics on my systems page). The TW AC + BN motor weighing approx 65kg rests on a HRS S1 platform and the whole caboodle rests on the mdf shelf. Mdf is not the best material sonically .
Slate is recommended by some TT manufacturers but is not available locally. Among the other options , plywood, acrylic or granite, what is recommended ?
Many thanks.

before i recommend the material bare in mind:
first of all the wall mount is never steady and as long as you're moving around your dwelling it shakes up and down even if you do not see it. that creates tension and apperently much heavier mass loads onto the material than whole structure weighs. so consider high school physics: lever, momentum and mass.
granite or marble wall mount stand together with your turntable will break your dry-wall even if you mount your structure into studs. for the metal studs i'd recommend removing a portion of other side dry wall and bolt-mount your structure through it. For any other than metal studs I'd recommend either reinforcing with metal or replacing wood studs by metal ones.

my personal preference is to plexi-glass 1&1/4"...2" thick. it's very easy to work with, very easy to set up, price efficient and great isolation qualities.
