Hear the Difference

Many audiophiles who prefer their music on-the-go use their phones, PCs, or tablets as their source for audio content, connecting their DAC directly to the device. Even though the voltage and current are low, the role and quality of the cable are still important with noticeable improvements in sound quality when using better cables.

With ddHiFi’s new Nyx series OTG cable, you’ll hear the difference.

Double-Shielded Data Cable Structure

The shielded structure of the Nyx cable isn’t suitable for the data portion of the cable since the data cable includes common transmission of current along with the digital signal. The stability of the current transmission depends on the number and purity of the conductors while the stability of the digital signal requires high conductor purity, reasonable twist structure, and a shielded layer design.

For the Nyx series, ddHiFi developed a double shielded parallel structure to shield current and data transmission respectively. Visually distinguishable, the pure silver shielding outer layer provides power transmission while the mixed silver and black shielding outer layer provides data transmission.
