The equipment rack is on a suspended wood floor with industrial vibration isolation pads, the kind used for vibrating equipment. I have used BDR, Herbies IsoPods, etc in the past. The EMM labs footers seem to be made with aluminum and some type of viscous material which I imagine is tuned for the chassis. Frankly, I have found isolation devices in the past to make very little noticeable difference, could be the maple rack does a pretty good job of isolation from ground vibrations. I would assume that if the maple rack is relatively inert, that the idea would be to couple (and drain equipment vibration) the player to the rack rather than isolate it from the rack - true?
