Glass or MDF Shelves

Have you seen the products over at:

Really nice and relatively affordable.

The glass does look better to me but maybe I put my Acoustic Signature on top of butcher block or something else

That’s a turntable. Turntables are special. In more ways than one. What they all love more than anything is mass. A close second would be stiffness. A close third, damping. The more, the better.

With a turntable, you will be well served to give serious thought to a dedicated turntable rack. These flimsy racks like VTI that are okay for everything else are just way too rickety for a turntable. Might work, depending on your particular location situation. Or might not. You pays your money and you takes your chances....

Thanks everyone @miller and @erik 
great thoughts. Yes for more a little more money I’m really liking the butcher block to have the mass and style, Thanks very much gents!!

Buy a sheet of 1/2" 9-ply Baltic Birch plywood, have it cut into shelf-side pieces. Put constrained-layer damping between pairs of the shelves, apply Minwax Clear Satin Polyurethane (beautiful!), and install. Better than anything you can buy, easy to do.
