The ddHiFi TC19BC Comet Gold is a premium USB-B male to USB-C male cable designed for digital audio data transmission between a computer, OTG-compatible smartphone or tablet, and a USB DAC equipped with a USB-B input. It features a flat parallel 5-conductor structure that enhances signal stability while maintaining excellent cable flexibility. The data lines (D+ / D-) use 25.6AWG high-purity 4N OCC silver conductors, ensuring outstanding conductivity and accurate digital data transmission. The power lines (V+ / G) are made of 21.3AWG silver-plated 5N copper to provide stable power delivery while minimizing transmission losses. The CC1 / CC2 lines use 32AWG tinned copper conductors to ensure reliable communication between USB-C devices. The entire cable is protected by SoftFlex PVC insulation, providing excellent flexibility and long-term durability against repeated handling. The connectors feature gold plating for reliable contact and excellent oxidation resistance. Measuring 100cm in length and weighing approximately 55g, the TC19BC Comet Gold is an ideal solution for connecting a desktop or portable USB DAC while ensuring stable, high-performance signal transmission.
