ABSTRACT:
An improvement in the high frequency sound quality of audio circuits using copper electrical interconnections is realized by replacing copper electrical interconnections with interconnections of a material exhibiting a greatly reduced skin depth at audio frequencies. At the moment, without the availability of practical room-temperature superconductors, the most practical method is to use a material possessing a high magnetic permeability. By this means, phase dispersion due to the skin effect is virtually eliminated.
