If you have a device that has direct contact from top to bottom, (12 o’clock to 6 o’clock) like single bearing devices, no matter what the materials used, it is damping -- not isolating. True isolation does not have a direct path between surfaces. Stillpoints patented technology stacks bearings such that there is no direct contact between the component and the surface upon which it rests.
Human hearing is generally considered to be 20Hz-20kHz. With electronics, Stillpoints' technology effectively functions over 20kHz. Typical damping products operate below 20kHz; thus shifting tonality. Despite this tonal shift, Stillpoints can easily be used with damping products to great success.
The materials used in Stillpoints are ceramics and stainless steel. They will last many lifetimes. What other product, from any industry, has the same permanence?
After a very short break-in period, the Stillpoints filter performs without change or degradation.
Considering the amount of performance and pleasure derived from a Stillpoint over time they are a unique bargain.
