I just checked. There’s a lot of effort that went into the footers and plinth for the Burmester Preamp. The footer is milled and has a carbon fiber cone on the bottom that sits on a carbon fiber disc set into a milled hollow in the plinth. The footer is not attached with a single central screw. Each footer has 3 screws 120 degrees offset (ie. In a triangle). There was a LOT of thought and effort that went into vibrational damping. And it shows since it is abjectly immune to any resonance control devices.
Interestingly, the Burmester amps just have pretty standard footers screwed in and respond well to after market footers.
