Sigma-X interconnects feature the PMZ (Precision Matched Impedance) conductors. They feature ultra-pure OCC Copper conductors, PTFE dielectrics, and precision braided shields that are extruded at one quarter the typical speed to achieve its level of precision. This precision results in superior signal fidelity, improved low-level detail and greater dynamic impact. The KPIP v2 (Kinetic Phase Inversion Process) conditions the conductors for a period of 4-days which enhances sonic performance and reduces the break-in or settling time.

These meticulously designed processes offer superior coherence, improved low-level detail, and stunning dynamic impact, creating an immersive and captivating listening experience.

Sigma-X interconnects elevate music reproduction by eliminating background noise, time smear, and phase distortions, unveiling your music with unmatched transparency and dimensionality. The cables deliver exceptional resolution, dynamic precision, and a balanced tonal spectrum, ensuring instruments and vocals resonate with life-like presence.

Sigma-X draws listeners into the heart of every recording, offering an emotionally engaging performance that reveals the finest nuances, even in the most complex musical pieces.

‌‌ArNi® Conductors
Shunyata developed this wire to be the finest quality wire available for audio purposes. The process begins with the highest purity of copper available – OFE C10100 or Ohno (single crystal). The conductors are then formed into virtual hollow tubes which eliminates skin effects as well as eddy current distortions. Premium fluorocarbon insulation protects the conductors and minimizes dielectric absorption and re-radiation, this greatly improves resolution and clarity. The wire then undergoes Shunyata's proprietary KPIP™v2  process for optimal conductivity.

Fluorocarbon Dielectrics
These ultra-high quality insulators are usually only found in wire used in the aerospace industry, satellites and the most expensive audiophile cabling. Fluorocarbon has special electrical characteristics; very low dielectric absorption, high dielectric strength and exceptional heat resistance.  When used in audio and power cables these dielectric materials reduce the perception of dynamic compression and improve low-level resolution and overall clarity.

Precision Matched Impedance (‌‌PMZ)
The Greek symbol Z stands for impedance. Shunyata's PMZ cables are built to exceedingly tight tolerances to minmize internal impedance fluctuations. Using high-precision manufacturing processes which run at one-quarter speed in order to create conductors with ideal electrical characteristics. This conductor surface variances, dielectric extrusion (aka insulation) and precision of the braided shield. This extra attention to detail results in superior signal fidelity, improved low-level detail and greater dynamic impact. 

Transverse Axial Polarizer (TAPc)
This is a Shunyata Research patent pending technology developed to improve the performance of their reference cables. The TAPc technology is a radical advancement of their original TAP technology which enables a significant reduction in the size of the modules – which for the first time allows this technology to be applied to power cords.  The sonic results of TAPc include a cavernous drop in perceived noise floor, effortlessly portrayed dynamics and a superb rendering of timing and coherency. The sonic benefits of the TAPc technology are quite simply unique and cannot be replicated by any competing product or technology. Even to an untrained ear, the effects of the TAPc are immediately apparent and repeatable across a variety of components and systems. In essence, the TAPc modules are force-multipliers that elevate the listening experience to a level many would not imagine possible.

Kinetic Phase Inversion Process (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 KPIP process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade.
