ddHiFi's TC19CC Gold L-Shaped 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
  
• Convenient and easy to use L-shaped design

Comet Gold Conductor Structure

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. The increased number of conductors does not affect cable flexibility, providing excellent bending performance.

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.

CNC Full-Metal Shielded Plug

The housing of TC19LL is machined from aviation-grade aluminum via CNC. The three-piece assembly structure fully shields the soldered area. The USB-C plug PCB is redesigned, resulting in a smaller profile than the TC09L plug.

The shell adopts a textured stepped structure, which prevents slipping when pinched by fingers, making plugging and unplugging more labor-saving and smooth.
