VIABLUE™ NF-S6 AIR Silver RCA analog cable: Our reference audio cable for a First Class listening experience. Specifically designed for the transmission of analog signals, NF-S6 AIR cables provide a clear, natural and perfectly well rounded sound. All frequencies are rendered in great detail and true to the original.
The unique structure of the NF-S6 AIR includes an Air Pipe System, which creates an air-filled space in the center of 12 conductors. These conductors form a perfect circle around an Air Pipe. This set-up allows for a complete separation of the conductors, which forms the basis of a complete and fast signal transmission true to the original.
The result: No disturbing temporary hold of electrical charges, so-called capacity, within the cable. The Air Pipe system also prevents inductance, unwanted magnetic fields. This leads to a rapid and pure transmission of all signals and full sound patterns.
