Machina Dynamic Brilliant Pebbles?

If you want a sincere answer, yes they have a modest benefit. It is not of the magnitude of raising your cables off the floor or of using better power cords, but I will neither sell the pair I have nor buy anymore. Of course, like most tweaks, speakers, or cables I have only a plausible explanation for why they benefit the sound.

Dopogue, like so many tweaks, resonances seem to be the explanation. The same goes for speakers and suspending wires; doesn't it.

I really don't know what is going on nor is our scientific explanation of much use. Trust your ears has always been my guiding principle. I bought these second hand having not heard a demonstration. The added and thus stayed. The same goes for the Intellegent Chip and in some applications the Shun Mook Mpingo pucks. I just cannot bring myself to try the Clever Little Clock, however, unless I hear a demonstration first.

Geoffkait, you are right I did not buy directly from you. I have removed the rubber rings. What is the relative effectiveness of having them in the corners as they were demonstrated at CES relative to on the transport?
