ddHiFi's TC19CC Gold Flagship Interconnect Cable Introduces a Five-Conductor Parallel Structure, Enabling Faster Device Recognition

• Built with flagship pure-silver conductors
• High-purity 4N Mono crystalline Silver
• Silver-plated 5N Long-grain Copper
• Available in 10cm, 45cm + 100cm lengths

Five Sets of Parallel Conductors

Building on the soft flexibility of flat cables, Comet Gold introduces a five-conductor parallel structure. Power lines run along both sides, separated by CC signal conductors in the center. The data lines use pure silver conductors, with two independently insulated pairs twisted together and wrapped in gold-plated shielding. This five-parallel design enables faster device recognition and is ideally suited for one-meter data transmission.

Directional Connection

When outputting USB audio signals, the system identifies an OTG device by detecting the resistor inside the USB-C plug. When a player acts as a USB decoding device, the mobile phone serves as the OTG output for music playback and the end connected to the player is the signal input.

If the player itself serves as the OTG input, the plug orientation must still be followed before connecting to other USB DAC devices.

Copper Gold-Plated Plug

The USB-C plug shell is made of pure copper with real gold plating, delivering excellent grounding and shielding performance, optimizing signal transmission. Compared with the standard Comet, the Gold version delivers a fuller, richer sound, better high-frequency control, and effectively reduces hollowness.

10/45/100

The TC19CC Gold is available in three lengths: 10cm, 45cm and 100cm. The 10cm version is designed for portable smartphone DAC/amps, compact and travel-friendly for on-the-go scenarios.

The 45cm and 100cm versions are suitable for connecting to desktop audio decoding equipment with USB audio input and other large-scale devices, meeting long-cable connection needs in fixed setups.

Curved Ergonomic Design

The cable end features an innovative curved, raised structure that fits the natural finger pressure angle, making plugging and unplugging effortless and comfortable. The tough metallic texture blends with smooth curved lines, combining practicality and visual aesthetics. Every connection lets you experience the dual quality of craftsmanship and design.
