I've just installed a Neuance Shelf under an Accuphase DP-75, which at 43 pounds has some vibration control built in. The improvement was striking, and while I love to tweak I don't expect to try to improve on this arrangement. It is important to get the underpinings right, and Ken Lyon at Greater Ranges (the Neuance company) was endlessly patient and helpful to me in planning a DIY spiked platform.
