Geoff, I agree with your underlying sentiment that it is unwise to disparage a tweak or a piece of audio equipment just because it is very expensive. I try not to do that. On the other hand, I do try to apply what knowledge I have of the relevant physics (college level, in my case) and electronics to understand how a product "works". Then I can judge better whether it is worth the cost. In this case, I don't see the connection. Absent magic, it seems impossible that a small wooden disc can "regulate" the resonance of other much larger and heavier objects of heterogeneous composition that happen to be in the same room with it. Since this claim is rather extreme, it behooves the maker to provide some rational explanation for the mechanism by which the claimed end is achieved.
