Hey Juan,
this is a SOTA rack, great!
The no. 10) isolation discs might be/is a starting basis.

Yes Joachim, this Artesania Audio are really first class. The isolation discs you mention have a slit where goes the spike but could be placed directly on a board. However it is important to see the system as a whole. In the case of the bamboo boards if I woud use some kind of damper IŽd use the metal discs with a felt underneath (Dampers from A.A.)
Another home made solution that I have used successfully with other Ikea boards is to place between two boards several Allsop Mouse Pad covering the entire surface, that way there is a layer of rubber between the two boards that serves as a damper. You can also try it between the two bamboo boards.
