The ZERO Series of audio interconnect cables represent the absolute state-of-the-art in audio interconnect design. No other interconnect design can approach the performance standard of a ZERO Series Interconnect. The design starts with Rectangular Solid Core® conductors. The RSC® conductors are specially shaped and frequency tuned to reveal more of the harmonic structure of the music than any other audio conductor. These conductors are suspended within a totally unique Teflon® tube. This tube within the ZERO Interconnect holds the conductors in position along the internal wall of the tube, without the need for extra dielectric/plastic materials that would affect the sound. The ZERO Series of interconnects are truly extreme cable designs. The signal carrying conductors within the cable have such high resolution, that all of the other parts and materials of the cable become the audible differences. If the materials or parts can influence and change the sound, then we work carefully to isolate the sonic signature of the materials and parts. It is therefore extremely important that all of the materials used in the ZERO Series have no “sonic signature”, meaning that the cables transfer the musical signal with the most clarity, neutrality and transparency possible. There are 3 levels of performance in the ZERO Series of audio interconnects, starting with the legendary ZERO Gold. The next product in performance (less) is the ZERO Onyx, and finally then to the ZERO Edge.

The ZERO Onyx provides a level of performance that may be the most popular choice for audiophiles. Although the ZERO Onyx does not use the vacuum-dielectric concept of the ZERO Gold, the ZERO Onyx does use the same construction design and all of the same materials as the ZERO Gold. So, the ZERO Onyx is the same as the ZERO Gold, but without the vacuum-dielectric system. The air-dielectric construction of the ZERO Onyx means that the RSC® conductors need to be insulated, but the insulation is a fine layer of aerospace polyethylene, a very neutral material with minimal audible effect.
