Silversmith Audio’s FIDELIUM speaker cable, derived exclusively from electro-magnetic wave equations, reflects our design philosophy in its purest form: A single, ultra-thin ribbon conductor per polarity; seamless from end to end and without traditional, sound-degrading soldered, welded, or crimped connectors; and individually laminated in an extremely thin, yet rugged, polyimide film in order to achieve a geometry with a primarily air dielectric.
The skin-effect characteristics of Silversmith Audio’s FIDELIUM alloy are up to 33 times superior to those of copper or silver. The FIDELIUM speaker cable, already at less than a thousandth of an inch thick, performs as if it were 5.5 times thinner, thus experiencing less frequency dependent attenuation and phase distortion than even a 0.00018 inch thick copper or silver ribbon or 64 gauge wire. The 2.25 inch wide speaker cable design gains further sonic advantage by avoiding the significant sonic degradation caused by traditional spade and banana connectors. As a simple yet elegant solution, the cable itself is notched (0.25 inch wide) to facilitate connection to most binding posts.
