Many sizes, shapes and constructions have been tried on Hifi cables. Electrical conductors have been made in many sizes, shapes and geometries. But as the dust has settled, a few design parameters have proven to be essential and several pattern has emerged. Cable Construction Guide gives a description of the general principles, pros and cons of several common cable designs. Good cable designs have a good ratio of conductor resistance to cable capacitance, conductor inductance to cable capacitance and low electromechanical resonance.
