    MY TAKE: Simply put, Shunyata Sigma cables are the best performing cable products I have ever experienced. They offer an other-worldy level of performance that is truly extraordinary. Whether it be the Sigma power cables, interconnects, speaker cables or digital links, Sigma products can elevate even the best systems to new levels of resolution and musical involvement. For those with the means, I can't recommend a product more strongly. - Galen Carol

    As the performance vanguard in the Shunyata Research cable line-up, SIGMA SERIES cables take the term state-of-the-art to an entirely new level with the introduction of two new cutting-edge technologies.
    Sigma Series interconnects include the Transverse Axial Polarizer (TAP) that minimizes a form of micro-distortion identified as electromagnetic polarization.
    The Sigma Series speaker cables incorporate a proprietary device called HARP that reduces current resonances within the cable, a concept that is somewhat analogous to diffraction in room acoustics. ~ Patents Pending ~

     

    Sigma – A Convergence of Science and Art -

    Sigma Series cables showcase technological innovation and design execution that simply does not exist elsewhere — at any price. Sigma Series cables combine meaningful parts innovations with objective measurement and an artisan’s eye for construction quality. Unlike many cost-no-object cable products that have little in the way of discernible science, Sigma Series products incorporate an array of definable technologies that sets the standard for quality and performance in the cable industry.

    Sigma Interconnects

    Analog Interconnects carry a system’s lowest-level signal. Unlike the high-speed signals in digital cables, or the mass-current traveling through power cables or speaker cables, analog Interconnects must be designed to perform a refined, yet simple purpose, which is primarily to preserve and protect the source’s original signal. With high levels of RFI, EMI and component-radiated noise ever-present, interconnects require careful consideration be given to isolation from their external environment. Less well known, but equally important factors affecting performance are internally generated micro-distortions such as skin-effect and dielectric absorption, inherent within all signal-carrying conductors.

    Shunyata Research scientist Caelin Gabriel, a recognized expert in area of signal-transmission and low-level signal resolution, has developed specialized metal treatments, conductor geometries and patented technologies that addresses both the external and internally generated distortions that interfere with the superior resolution of the original signal. These technologies start with the finest raw material in Ohno Continuous Cast Single Crystal  Copper, which is used in all Shunyata Research interconnect models. The Ohno Copper is then wound into hollow core conductors which Shunyata terms VTXTM (Virtual Tube Conductor). VTXTM conductors dramatically minimize conductor distortions known as skin-effect. In the Delta model interconnects, the conductors are made larger and include the finest fluorocarbon dielectrics for improved resolution and for the first time, KPIPTM (Kinetic Phase Inversion Process) is used to pre-condition conductors well beyond what normal break-in accomplishes. From Alpha through Sigma interconnects, Shunyata’s most advanced patents and technologies, such as ΞTRON® and the Transverse Axial Polarizer (TAP) are deployed, further minimizing distortion and dramatically improving resolution.

     

    Technological Innovation -

    As the performance vanguard in the Shunyata Research’s cable line-up; Sigma Series cables take the term ‘state-of-the-art’ to an entirely new level with the introduction of two new cutting-edge technologies. The first, integrated in the Sigma Series interconnects and digital cables, is the ‘Transverse Axial Polarizer’ (TAP). It minimizes a form of ‘micro-distortion’ identified as ‘electromagnetic polarization’ that reduces ‘sonic glare’ while increasing clarity and coherency. The second technology incorporates a proprietary device called HARP that reduces current resonances within speaker cables — a concept that is sonically analogous to the use of diffusion panels to treat frequency irregularities in room acoustics.~ Patents Pending ~

    Shunyata Technology – Cable Products

     

    Highest Purity Copper -
    Shunyata Research uses only the highest purity of copper available for the production of its wire products. OFE Alloy 101 or C10100 is the highest grade of copper with a minimum 99.99% purity and a conductivity rating of 101% IACS. OFE stands for oxygen-free electrolytic and supersedes the term OFHC (oxygen-free high conductivity). C10100 is the only grade of copper that comes with a written certification of purity. Certified by ASTM F68 C10100.

     

    Single Crystal Technology -
    Ohno wire, also called PCOCC was invented in 1986 by professor Atsumi Ohno of the Chiba Institute of Technology in Japan. Copper wire is created by an extrusion process that pulls a rod of cold copper through a small orifice which creates multiple crystalline boundaries. By contrast, Ohno wire is made by a process using heated molds that cast a wire to form a single crystalline structure. Ohno wire is well known for its exceptionally pure, grain-free sonic qualities.


    VTX Conductor Design -
    Shunyata Research’s exclusive VTXTM conductors are made in the shape of hollow tubes. Since current can ‘only’ travel through the outer rim on the wire, there are no skin effects or random eddy currents. VTXTM conductors are made from pure OFE C10100 or Ohno (single crystal) copper.


    KPIP Conditioning -
    KPIPTM (Kinetic Phase Inversion Process) was developed by Caelin Gabriel after years of research into the underlying causes of various effects such as burn-in, wire directionality and the effects of cryogentic treatment. He discovered that there was an underlying core principle that burn-in and cryogenics only “partially” addressed. Once the governing principle was understood it became possible to create a processing technique and machine that could virtually eliminate the need for burn-in and cryogenic treatment.

    Unique Conductor -
    ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest purity of copper available – OFE C0100 or Ohno (single crystal). Then it is formed in virtual hollow tubes eliminating skin effects and eddy current distortions. In addition, the wire undergoes our proprietary KPIPTM process.


    Patented ΞTRON® -
    ΞTRON® is a technology developed by Shunyata Research that prevents dielectric absorption and re-radiation in signal transmission. It requires a special type of conductor that has two signal paths and an electric field compensation circuit that creates a cancellation signal that prevents the insulation from developing a charge. ΞTRON® cables preserve the integrity of the source signal even when using very long runs of cable. Patent US 8,912,436, Patent Ch ZL201180047344.2.


    Custom Connectors -
    Many audiophile grade connectors are made from brass or bronze. While some may get a plating of silver, gold or rhodium, the majority of the current is carried by the contact’s base-metal. CopperCONN® connectors contain pure copper contacts which has a much higher conductivity that brass. The difference in performance is clearly audible.


    Interchangeable Connectors (Venom Series) - 
    The STISTM speaker terminal system was designed to eliminate the high cost and complication of speaker cable termination. The system makes it possible to use the same speaker cable with a variety of different amps and speakers. If a spade is damaged, you can simply replace it without sending it to the factory for re-termination. STIS™ interchangeable terminals have undergone extensive user listening tests to ensure that they provide the finest audio performance that is equal or superior to non-replaceable, soldered terminals.


    TAP -
    TAP (Transverse Axial Polarizer) is a device that interacts with the electromagnetic field generated by the signal traveling along the signal cable. TAP improves the sonic performance of the cable by modifying the behavior of the electromagnetic wave that surrounds the signal cable. In effect, the TAP blocks longitudinal-oriented waves while passing transverse oriented waves. The effect in sonic terms is like using polarized sunglasses to reduce reflected sunlight. Correcting polarization micro-distortion reduces what some call sonic glare. ~ Patent Pending ~

     

    Precision Matching -
    Shunyata Research digital cables are produced using a Precision Matched Z (PMZ) concept. This means that tolerances of the conductor surface, dielectric extrusion, and the precision of the braided shield are held to minute variances. To achieve these tight tolerances, the extrusion and braiding machines must be run at one-quarter speed during the manufacturing process. The result is better performance through a reduction of cable-induced ‘signal jitter’. (Note: Z means impedance)
     

    Superior Termination Techniques -
    Crimping, soldering, brazing and cold soldering are all inferior methods of joining two wires or terminals together. Sonic welding uses high energy sonic waves to literally join two metals together at a molecular level. There is no solder or intermediary metals involved in the process.

     

    HARP -
    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.
