I have a VPI turntable stand for my Clearaudio Innovation. I use a 3' maple platform as a top supported with cones. The cones screw into the bottom of the platform. My other stands are maple, but for my turntable I want something more solid that is not affected by vibration.
My stand is filled with sand and it helps quite a bit. Use high grade childrens play sand or that fine gray colored sand. Don't use regular sand.
