After years of development, 512 Engineering is pleased to introduce Solus cable technology at AXPONA 2026. What started as an observation about dielectric constants became a new way of designing cables from the ground up. Solus is a new method of incorporating air into the dielectric layer of a cable, reducing the effective dielectric constant closer to the ideal of air itself while simultaneously improving capacitance per unit length, signal propagation velocity, dielectric absorption, dielectric loss, and characteristic impedance control.

SOLUS CABLE TECHNOLOGY
Air is the ideal dielectric. We get close.

The insulation surrounding a cable conductor isn't passive. It stores energy, slows signals, and adds noise in ways that are audible, measurable, and until now, unavoidable. Solid polymer insulation has a fixed dielectric constant. Your music pays the price.

Solus replaces it with a braided structure that incorporates air, bringing the insulation's electrical behavior as close to nothing as practical construction allows. The result is a cable that gets out of the way. Less smear. Less storage. Less between the signal and your ears.

SOLUS | USB AUDIO CABLE
Every USB cable ever made was optimized for 480 MHz. USB audio doesn't use 480 MHz.

USB audio delivers music in packets, tiny bundles of data arriving at your DAC one thousand to eight thousand times per second. Your DAC builds its clock from the regularity of those arrivals. That clock is your music.

Cable signal integrity at 1kHz to 8kHz, not at 480 MHz is what determines what you hear. Solus USB is the first cable designed with that frequency established as the primary design target.
