RE: In the interest of sharing

Nice idea! I was using furniture "cups" but the pulls look great. FWIW I have the cup then the ball then a cup on top as a hat then the brush on my headphone amp and my Big Ben.

So far I think the brushes are sounding better than the rollerballs but maybe the drawer pulls would help.

FWIW the guy who saw me doing diy roller balls suggested the brushes as a better options. Seems to be the case.

Here is some more info he posted:

The bristles of the brush work best when under compression as this creates a bow in the bristle which causes the bristle to act as a spring permitting booth later and vertical motion. The act of bending is resisted by torsion within the fibers this generates heat which is how energy is dissipated. The multiple fibers of the brush also rub against each other this too generates some additional friction and the fibers also damp the motion of each other providing stability preventing a large mass resonance. The mechanism is not unlike a weight upon a spring suspension a spring which is damped in the vertical plane and stabilized/damped in the horizontal plane. Coil springs are used to achieve the similar results especially on heavy components such as amplifiers and turntables. Foam materials of both closed and open cell construction could be used an extension of this wold be a single closed air bladder or bag with sufficient stretch in the wall material of the bag.
