Guys who make granite countertops don't have much use for the sink cut-outs. They are often appropriately sized for turntables, and you can acquire them inexpensively. The granite guys will often square-up the sides and can even polish the sides, if you like. I got several for $10 each.
I put five 2 inch rounds of 1/2" thick Sorbothane on top of my shelf and under the granite. I then replaced the stock feet on my 'table, and replaced them with threaded-in cones. The tip of the cones fit into a small depression on flat discs. The discs sit on same diameter sized 1/8" thick Sorbothane, which sits on the granite. Made a huge difference on my non-suspended 'table for not a lot of dollars.
Granite comes in a wide variety of colors and patterns. Blue Pearl (a deep blue and beautiful granite), which comes from Sweden, is probably the most dense, closely followed by Emerald Pearl. Southern grey is an inferior granite, but Barre (Vermont) grey is a very durable and dense stone. There is also a black granite with gold-colored flecks. I forget its name, but it is stunning.
Happy listening!
