No subject in High-End Audio is accepted with so much enthusiasm and so little understood. Vibrations are one of the most important sound affecting factors in audio-systems. Each device, even each electrical component creates vibrations and passes these on, mechanically and electrically. These disturbances overlay to the origin music signal and are perceived. Superpositions cancellations and material sounds are resulting. Some high-end gurus compare this issue with the electrical ground-loop problem. There too "vibrations" have to be grounded. To avoid turbulences (ground loops) they have to be released on a defined point (ground star-point) to the rack or base. To make this a reality, I offer two different materials with different acoustic properties. This way you can adapt your gear even better to the respective environmental variables. My favourites are wood twice and acrylic once, whereas this one is placed close to the transformer.

Acrylic Isolation Feet

These feet consist of two plates and a ball. The plates are made of acrylic glass with exeptional damping properties. The plates have a diameter of 40mm and the ball 10mm. Together the have a height of 22mm. Included are three different ball materials: plastic, steel and ceramic.

Isolation Feet Wood

These feet are made of bongossi (aka ironwood) lenght 33mm, height 22mm. Top and bottom are perfectly milled and polished spheric.

Both supports allow a degree of freedom in horizontal plane. Mechanical energy that is induced in the supported device from outside (structure-borne noise) or is generated in the device will be transformed to one part in the horizontal plane and will be released to another part in the rack and/or the ground.
The set consists of two wooden feet and one acrylic foot. Of course you are free to combine the feet arbitrary thus you have great control over tonal balance and soundstage. Supports you don't need you can simply return! With comprehensive set-up instructions.
