can all have positive effects in many cases. I use all 3 in various locations. One manufacturer's explanation for the efficacy of isolation bearings, such as Aurios or Rollerblocks, is that such devices decouple electronics from the supporting surface in the horizontal plane, where most environmental vibration occurs. Vistek (I think that's the name) made isolation bearings for semiconductor manufacturing equipment before they offered products for audio use (Aurios). The intent was to prevent horizontal vibrations from entering the equipment from the environment. I suspect that the brush tweak behaves very much like isolation bearings with some damping thrown in.

sounds right.
FWIW the inmate who mentioned the brushes, had this to say:
lower friction more possible motion the reason I gave up on roller blocks back in the 80's the sound was great but they were too much fuss and still are but they still sound great. A smaller ball is better than a larger ball all you need is for the ball to sit proud of the top of our cup by a mm or two. I have been experimenting with finger nail brushes they need to have enough stiffness to only just compress and yu have the sane dissipation of horizontal vibration as well as a vertical compliance so better than a ball alone which only dissipates energy in the horizontal no vertical vibration dissipation.When set up properly I cannot tell any difference between my steel ball on steel cup or my fingernail brushes. No balls to lose nor components falling over or swaying about. I much prefer the brushes.
Over the rubber/ cork blocks and the diy rollerballs I think the brushes are best. Though 2 components have rollerballs with brushes.
