Recent years have seen ferment in every area of high-end audio. Nowhere has this produced more of a revolution (controversy to match) than with audio cable. Many sizes, shapes and constructions have been tried, but as the dust has settled, a few design parameters have proven to be essential. As a result, several general approaches have prevailed. The best contemporary designs all share a good ratio of conductor resistance to cable capacitance, conductor inductance to cable capacitance and low electro-mechanical resonance. Helically wound multi-filar cables and braids now predominate. Symmetry, balance, mechanical stability and quality of materials are features that differentiate today's leading cable designs. Following is a description of the general principles, pros and cons of these designs (not discussed here are flats, tinsels, ribbons, co-axes, and certain other random or asymmetrical constructions). Electrical conductors have been made in many sizes, shapes and geometries, but over the years a definite pattern has emerged. Contemporary designs have a good ratio of conductor resistance to cable capacitance, conductor inductance to cable capacitance and low electro-mechanical resonance. Designs that do not incorporate these aspects, don't last.
