Granite under wood for better isolation?

Me too. Think it is ok to put a film of plastic on top of the sand?

Put the granite into a sand box. All ringing will be gone.

That is exactly what I have. Unfortunately, it doesn't work. It helps some but the granite still rings. that is why I placed Stillpoints between the granite and my turntable, to isolate the table from the granite.

Dan ed, I don't understand. I don't use granite anymore, but my granite in sandboxes where the granite had no contact with the side of the sandboxes, never rang.

I doubt if there is much benefits in having the granite under the StillPoints. I am assuming that you have just a shelf under the granite.

Believe it or not, I just bought a sheet of MDF from Home Depot. They cut it to size and it is actually the best so far. Better than the maple or granite. I have it under 4 Vibrapod isolators. 5 bucks. In fact, it is by far the best. I put the Maple wood under my isolation transformer. The Granite has not worked for me so far and the most expensive as well.

Tzh21y, this all suggests how different things work in some systems and not in others. I can only stand Vibrapods under things that have nothing to do with music. I tried MapleShade maple board and their special feet also, but returned them immediately.

I have many polished pieces of granite for free to anyone coming by to pick them up. I will not ship unless you pay me a $1000 each to pack them. :)
