Detailed Description

X-Tube™ Technology

The X-Tube™ technology forms the cable conductors into a tube-like shape around a central insulating rod. This design equalizes current densities, resulting in very low inductance and a consistent load to the amplifier. The outcome is a cable that preserves fine musical details and handles rhythms naturally, outperforming higher-priced rivals.

Air Gap Dielectric

The Air Gap dielectric increases the separation of conductors inside the cable, enhancing the amount of air between them. This reduces dissipation and capacitance, leading to audible improvements in timing and rhythmic accuracy. Despite the increased separation, the XT40i retains a cross-sectional area suitable for long cable runs.

Pure Oxygen-Free Copper

The XT40i uses 99.999% oxygen-free copper, which ensures minimal signal loss and high purity of the audio signal. This material choice contributes to the cable's low DC resistance and enhances its overall audio performance.

Low DC Resistance

The cable's low DC resistance of 8.0 mΩ/m ensures an unrivaled frequency response. This feature allows the XT40i to deliver clear and accurate sound across the entire audio spectrum, making it ideal for high-end audio setups.
