Hanging from the ceiling is not only a cost effective solution to your problem, but also a superb isolating technique. The only vibrations that get feed back into the turntable are airborne, but they do not couple very well with self/turntable unit. I use picture hanger wires with turnbuckles at three corners, which really helps in the levelling process. The wires barely show, giving my Alex III and masonite shelf an errie self-suspended appearance.
