Emailists,
As a user of Sistrum and maple platforms, I don't feel they use the same philosophy- maple has (as everything else) it's own resonance freguency, and instead os "draining" vibrations away from the supported component, they "accumulate" that energy, and then release it back ( approx. the same, as the speakers cabinets do, causing "smearing" of the sound).
Sistrum on the other hand do not store energy, because of the different properties of steel vs. wood, and do release the energy into the integrated metal cones.
Under the speakers, in particular, maple on brass cones absolutely "killed" the sound, robbed it of definition, energy and dynamics. Herbies products in the same application, were even worse.
