Know before you buy
The hidden joint design is engineered to reinforce the connection point between the cable and the plug. This prevents the outer skin from fraying or breaking over time, which is a common failure point in standard audio cables.
The RC20A uses color-coded connectors for easy identification. The black connector represents the left channel, while the red connector represents the right channel.
PCOCC (Pure Copper by Ohno Continuous Casting) is used for its high purity and superior conductivity compared to standard copper. When paired with the cable's independent shielding, it ensures a clean, interference-free signal path for your desktop audio setup.
These cables are specifically optimized for compact desktop setups, such as connecting a small DAC to an amplifier. Given their 20cm and 40cm lengths, they are best suited for devices placed in close proximity rather than long-distance home theater runs.
The integrated dust-proof shell protects the gold-plated contact points from debris and oxidation when not in use. This helps maintain consistent conductivity and signal integrity over the life of the cable.
