More than 20 years ago Stage III Concepts brought to market the very first silver ribbon/air-dielectric cable specifically for audio power delivery. Its evolution recently culminating in our flagship power cable, the A.S.P. Leviathan, considered by many to be one of the best audio power cables in the world. Our new A.S.P. PROTEUS maximum current, precision power cable borrows many essential elements from the Leviathan along with some from our award winning (Positive Feedback Magazine 2016) A.S.P. Medusa speaker cable.

The A.S.P. PROTEUS employs the same expanded cross-section, heavy gauge AeroStrandUltra™ conductors as the Leviathan. Our proprietary radiation-invulnerable shield blocks all external airborne interferences and is further enhanced by extreme mechanical damping, similar to that found on our Medusa speaker cable. The conductor arrays in these cables are fully encased in our granulated H.D.A. (High Density Alloy) which is ideally suited to damp and completely nullify induced vibrations that commonly affect audio cables running along the floor. Its unique and carefully calculated design makes the PROTEUS one of the only audio power cable designs in the industry that is tailor-made for power distributors/conditioners, amplifiers or any high-power component that is positioned on or near the floor of the listening area.

PROTEUS power cables are a genuinely revelatory experience: utterly silent, yet coherent and powerful. Yet another inimitable Stage III cable that is painstakingly assembled entirely by hand with 100% proprietary elements, and absolutely no commercially produced or “off-the-shelf” components. A reference-level technological work of art to unveil the sonic truth your system is truly capable of.
