No cable can pass a signal with absolutely zero loss, that’s physics fact. The difference between “good enough” and truly reference, is which parts of the signal you choose to retain.

XerXes Reference Cables are engineered around what actually matters to human hearing. Building on the work of Helmholtz and the science that followed, we focus on preserving the low-level harmonic information your brain uses to tell one instrument from another, even when they play the same note. Those tiny tonal amplitude variations, not just basic frequency or phase, are what create realism, texture, and emotional impact.

As music moves through an audio system, every stage adds its own problems: power-supply noise, transformer fields, coil saturation, grounding issues, and more. By the time the signal reaches your speakers, much of the fine detail and nuance can be blurred or stripped away.

XerXes is designed to fight that loss at every link in the chain. Our reference cables and power products are rooted in measurable engineering that preserves the integrity of the musical information, not only the big, obvious parts, we focus on the subtle cues that make a performance feel alive.

The result is weight, speed, and authority with precise spatial imaging and unwavering accuracy, revealing the emotional core of the music and letting your system perform at a level that feels unmistakably “right.”
