How does damping an interconnect do anything?
… A. It is not the interconnects themselves that really need to be damped. Damping the interconnects helps eliminate airborne vibrations from the signal path and reduces vibrations being conveyed from one component to another. Any electronic part that amplifies, rectifies, or in any way transforms the audio signal will introduce distortion in the presence of microphonic vibrations. Tubes, capacitors, and digital processors are particularly sensitive. Interconnect dampers help to keep microphonic vibrations from finding their way to these sensitive electronic parts.
