The British company Musical Fidelity's interconnect cable uses pure silver PCOCC conductors, premium RCA bayonet connectors, three screens and two external RF absorbers.
The cable uses POCC (Pure Ohno Continuous Cast) silver wire. It has very low resistance and capacitance.
The RF absorbers are not in the signal path, their function is solely to absorb any RF signals.
Nu-Vista does not have the brightness that is usually associated with silver cables.
