Know before you buy
Unlike standard cables that bundle power and data together, the TC09S uses a double-shielded parallel structure to physically separate the power and data lines. This design minimizes electromagnetic interference, which helps maintain a cleaner digital signal for your DAC or audio device.
Yes, the TC09S is designed specifically for OTG (On-The-Go) use, making it compatible with most USB-C smartphones, tablets, and portable DACs. It ensures a stable digital connection for high-resolution audio playback.
Litz conductors are composed of individually insulated strands, which helps prevent the skin effect and signal loss at higher frequencies. By using high-purity silver and oxygen-free copper, the cable ensures efficient, low-resistance transmission for both power and data.
The 10cm length is specifically chosen for portable stacks, allowing you to connect your phone to a DAC/amp without excess cable clutter. It is compact enough to fit easily in a pocket or small carrying case.
By isolating the power transmission from the data path, the cable reduces the noise floor caused by power interference. While the impact depends on your specific audio chain, it is designed to provide a cleaner, more stable signal that can result in a more refined sound.
