All 6 Series audio cables are meticulously assembled by hand in Orlando, Florida. 6 Series single-ended RCA cables start with ultra-pure, highly conductive oxygen-free copper (HC-OFC) developed specifically for audio applications. Each conductor is designed with solid double-gauge wires that are mathematically and tonally chosen to support low, mid, and high frequencies for natural-sounding cable. The individual insulation of each cable results in zero interaction between wires and better sound quality. Unbalanced analog audio systems will benefit from the use of Tributaries' Twin-Axial cable design. The precision stranded Twin-Axial design has dedicated conductors for the positive signal and negative return signal, plus a heavy shield that is connected to the source end only. In this design, the shield will capture any induced interference and send it to ground at the source end, thus isolating noise from the input stage of the load. This setup ensures clear signal transfer with as balanced overall noise rejection as possible. The end result is a neutral sounding cable. The 6 Series single-ended audio cable is available in pairs and mono cables in lengths from ½ meter to 4 meters with custom lengths available..PZA MORE SPECS
