I've advocated implementing laminated bamboo boards for vibration control purposes for quite some time now. It can be a good tool for system tuning purposes.
Thick maple boards squash dynamics, IME. Perhaps the enormous Mapleshade brass cones and Isoblock rubber/cork pads would counteract this finding. However, I found that implementing a thick maple board as a base layer (spiked to the floor in my case), then positioning another type of board on top of it, with vibration control pads placed between the two boards acting as a vibration blocking layer can be a very good thing, rather than a constrained layer sheet which can produce too much damping for the purpose. It's important to allow the bamboo board to resonate to a degree rather than totally deaden it. Customized system tuning efforts can be accomplished by experimenting with various types of vibration control footers placed above *and* below the bamboo board positioned on top of the thick maple board.
For your application, I suggest placing a 3/4" laminated bamboo board on top of the thick maple board, with a set of four Herbie's Audio Lab Big Fat Dots (dBNeutralizer pads) placed between the two boards acting as a vibration blocking layer material. However, recent experiments using a set of four carbon fiber composite discs, with a Herbie's audio Lab Thin grungebuster Dot affixed both above *and* below each carbon fiber composite disc performs even better, IME. Additional vibration control footers placed under the component positioned on top of the bamboo board is advisable, since the sonic characteristics of the bamboo material tends to interact well with vibration control footers, IME. YMMV
