Do natural colored bristles sound better than black bristles? Do natural fiber bristles sound more analogue and synthetic bristles more digital? Inquiring minds want to know.

it is a shame that you prefer to act the fool rather than engaging in a discussion to learn more about what the mechanisms at play with the brush actually are.
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.
Other materials can be employed to absorb and dissipate unwanted vibration with the materials either under compression or tension or using tortion all manner of natural or synthetic materials might be suitable. You could compress a gas or use a vacuum to achieve your desired results. You spend your time posting thoughtless jokes or you could contribute to the discussion by sharing your thoughts and ideas.

Much apologies if my sarcasm was missed. I was merely making fun of the days of Dr. Low Mu claiming that black insulation on wire degraded sound. I do believe in using footers and other devices, and I do appreciated learning about what others have tried in the DIY and lower cost options. spending $200+ per footer makes no sense when both physics and empirical evidence suggests that sufficient isolation can be had for much less. Thanks for your thoughtful posts.

Cpwill: thank you for your post it is much appreciated. It has been my experience that colour additives many of which are mineral based can have in some cases noticeable impacts upon dielectrics in practical use both in how they impact the physical characteristics of the insulation and in how they sound.
I hope that you do some experimenting on your own and see just what can be achieved to make substantial improvements in your own system at a fraction of the cost of many of the generally accepted tweaks available. Forgive me if I failed to appreciate your humor, I find I tire of comments so often made by those who neither know nor care to know yet seem so willing to troll. They will complain that things cost too much yet also complain when almost free option are offered. Some will make little of others who have often made considerable efforts at their own expense and yet who are willing to share finding on public forums. Their jokes and ridicule are not deserved nor appreciated when nothing but kindness has been extended to them. Differences of opinion and even disagreements are fine and should lead to open discussion from which all may benefit.
Thanks again for your follow up post.
