At the core of the Sigma-X design is Shunyata Research's TAPc ( Transverse Axial Polarizer ) technology, which reduces subtle micro-phase distortions. This results in an exceptionally clear, open, and focused soundstage, allowing even the most delicate musical details to be expressed with unparalleled precision.

Sigma-X also features HARP technology which lowers cable induced noise by controlling phase distortions created by signal reflections and resonances. By breaking up these resonances, HARP enhances both resolution and coherence, bringing a new level of definition and control to the system's overall performance.

Shunyata's VTX-Ag conductors are made from both silver and copper conductors, in a coaxial geometry to combine the speed and clarity of silver with the warmth and weight of copper, delivering a full-bodied sound that balances impact and refinement across all frequencies. Finally, the KPIP v2 ( Kinetic Phase Inversion Process ) conditions the conductors, reducing break-in time and maximizing sonic performance.

TAP ( Transverse Axial Polarizer ) is a patent-pending technology developed by Shunyata Research to enhance the performance of its reference signal cables. The evolution of this technology has led to the creation of TAPc, a groundbreaking advancement that significantly reduces the size of the modules, enabling their application across a broader range of cables, including power cords, interconnects, digital cables and speaker cables.

The sonic results of TAPc technology include a profound drop in perceived noise floor, effortlessly portrayed dynamics, and an exceptional rendering of timing and coherency. These benefits are unique to TAPc, setting it apart from any competing product or technology. Even to an untrained ear, the effects of TAPc are immediately apparent and consistently repeatable across various components and systems. Essentially, the TAPc modules act as force multipliers, elevating the listening experience to levels many would not have thought possible.

HARP was discovered through Gabriel's research into 'current drift' and audio frequency current resonances that occur in speaker cables. Theoretically, a speaker cable may develop current resonances in the audio band, being roughly analogous to standing waves (modals) in room acoustics. The ‌‌HARP module acts as a current mode diffraction device that breaks up these resonances, improving the perceived resolution and coherency of the system.

Shunyata's VTX-Ag cables are uniquely constructed with both an inner, center conductor made of pure silver and an outer concentric ring conductor made of pure copper. It's made using the finest fluorocarbon insulation to minimize dielectric absorption and re-radiation which translates to an improvement in resolution and clarity. VTX-Ag delivers the speed and clarity of silver and the midrange warmth and three dimensional power in the lower octaves of copper without imparting any of the negatives associated with either metal. – The best qualities of silver and copper combined.

KPIP v2™ Shunyata Research's proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP v2™ processing which refines conductor metals at a molecular level. This dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation. When compared to the original process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.

Fluorocarbon dielectrics are usually only found in wire used in the aerospace industry, satellites and only the most expensive audiophile cabling. It has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance. When used in audio and power cables is reduces the perception of dynamic compression and it improves sonic low-level resolution and clarity.
