    MY TAKE: Simply put, Shunyata Sigma Series 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


    “Now we come to the inevitable question: how do the Sigmas sound? The simple answer is that they sound like nothing I’ve ever heard -- nothing at all, in my experience.
    “… they remove a barrier between you and the utterly visceral, thrilling experience that is live music.
    ” – Vance Hiner, The Audio Beat

     

    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-edgetechnologies.
    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

    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 POWER CABLES

    Over the past 20 years, Shunyata Research has invested enormous resources into the scientific research, measurement, and materials development of its many power cable models. Shunyata is the only company to have developed its own DTCDTM Analyzer that precisely measures instantaneous current through contacts, wires, switches and breakers. We are also one of the only companies that manufacturers all of its own power wiring, terminals and connectors. Shunyata Research treats the design of its power cables as the most important cable in any entertainment, recording or medical system.


    A common misconception regarding power cables is that they represent the final link in the transfer of power after traveling through miles of power lines and in-home wiring.
    The power cable is actually the first two meters of power wiring that the audio component sees — electrically speaking. In effect, the power cable is an extension of the transformer in the component’s power supply.


    Shunyata Research has developed advanced conductor geometries, electrical contacts, power connectors and junction-to-junction bonding techniques with measurements provided by our exclusive DTCDTM Analyzer. Shunyata Research’s NR Series power cables have built-in noise filters that measurably improves CCITM (Component-to-Component Interference) by reducing conducted power line noise and radiated RFI/EMI interference. Some of the key features of our power cables include: pure OFE (Oxygen-Free Electrolytic) copper; VTXTM ‘hollow tube’ wires; CopperCONN® connectors made with pure copper contacts; and built-in NR noise reduction filters. Last but not least, Delta,Alpha and Sigma series power cables are conditioned with our proprietary Kinetic Phase Inversion Processor (KPIPTM)that improves performance and eliminates burn-in issues.

     

    Sigma NR Power Cables -

    The Sigma NR power cable builds upon the worldwide success of its predecessors with massive 6-gauge (VTXTM) hollow-core conductors and Shunyata’s own CopperCONN®, solid copper connectors. The Sigma NR’s meticulous design and vanishingly low-resistance to peak current (DTCDTM) delivers unparalleled performance when used with even the most current-hungry amplifiers. It’s built-in wide-bandwidth noise filtration system reduces power-line and component generated power supply noise, making it an ideal choice for source components, power amplifiers and digital systems. Shunyata’s Sigma NR power cable’s advanced materials and standard-setting technology raise the performance bar for others to follow.

    The Sigma NR power cable is the ultimate expression of Shunyata Research’s Noise Reduction series. Six-gauge VTXTM (hollow-core) conductors equip it to handle the highest-powered amplifiers and yet it is surprising flexible for such a large diameter cable. CopperCONN®, pure copper connectors, are the best in the business. KPIPTM eliminates burn-in issues.


    REVIEWS:
     

    The Audio Beat: “In the world of high-end audio, cable brands are a bit like religious denominations. Each has its adherents and detractors. Some people use cables as tone controls, some apply them like Band-Aids, and others are looking for a way to eliminate their influence completely. After years of experimentation, I have found myself attracted to that last camp, even though I know it’s hopelessly idealistic. The best cable is no cable sounds good on paper, but there will always be a transmission method and that method is bound to have an impact on the final sound. Even our own ears color what we hear. So, a more achievable goal would be to find a method of transmitting electronic signals that has the least possible effect on those signals.

    “Effect reduction, as I'll call it, is one of the reasons I’ve used Shunyata interconnects and speaker cables in various iterations for almost a decade. My previous reference wires were selected for their warm character, something I thought I needed for the relentlessly analytical solid-state front-end and unforgiving speakers I had at the time. Once my reference system improved a couple of notches, I began looking for cables that would begin to match the transparency of the better components. Shunyata’s Python speaker cables and interconnects were just the ticket. From there, I graduated to the company’s Zi-Tron Python cables and most recently to its Zi-Tron Anaconda models. In the process, I became a believer in the "full loom" concept of cable upgrades after several less-than-successful attempts at mixing and matching brands.

    “It has been six years since Shunyata unveiled its Zi-Tron lines, and a lot has been going on in company founder Caelin Gabriel’s Poulsbo, Washington, laboratory. In addition to incorporating innovations from its power products, several brand-new patent-pending technologies have been added to the latest flagship -- the Sigma Series cables.

    “First, these new interconnects, speaker cables and digital cables all use Shunyata’s VTX conductors, which first appeared in the company’s best Zi-Tron power cords and are made in the form of virtual hollow tubes. Shunyata says these conductors eliminate random eddy currents and skin effects that can cause signal distortion.

    “While the Sigma cables continue to be based upon Shunyata’s patented Zi-Tron circuit, which the company says "prevents dialectric absorption in signal transmission," they’ve also upgraded the speaker cables with the world’s latest and highest-grade oxygen-free electrolytic copper alloy, known as OFE Alloy 101. Further, all Sigma interconnects are made with the Ohno continuous-cast process, which does not rely on common extrusion, but instead utilizes Japanese inventor Atsumi Ohno’s method of using heated molds to cast the copper into a single crystalline structure. Shunyata believes this method results in sound that is especially pure and grain-free.

    “All Sigma cables also go through the company’s proprietary Kinetic Phase Inversion Process (KPIP), which eliminates the break-in process typical of many high-end cables. Shunyata founder Caelin Gabriel is particularly proud of this breakthrough and says that cables treated with KPIP are far more transparent, stable and free of distortion than cables that are broken in by traditional playback or other burn-in technologies, regardless of how long those methods have been applied.

    “In addition to all of these innovations, Shunyata introduces in the Sigma line three new technologies. The first involves the elimination of soldering from its speaker cables, which has been replaced by a highly specialized sonic welding process that bonds metals together at the molecular level. One sonic welding unit costs in excess of $60,000 and all Shunyata’s techs must go through an extensive training process in order to use the devices. The result, according to Gabriel, is that the sonic signature of solder is entirely eliminated. Those who are skeptical must bear in mind that equipment designers from every field of high-end audio agree that the type of solder used can have a profound impact on a component’s sound, so no solder at all should be a clear advancement.

    “Each Sigma analog interconnect and digital cable sports a Transverse Axial Polarizer (TAP), which looks a bit like the barrel of a ray gun. A gold-plated copper honeycomb disc is encased in a glass tube positioned on each cable near the upstream connection. According to Shunyata, the patent-pending TAP device modifies the electromagnetic wave field that surrounds a signal cable. Gabriel compares the TAP’s sonic effect to how a good pair of polarized sunglasses alters sunlight; by correcting wave polarization, the TAP reduces what might best be described as sonic glare by altering the angle of the electromagnetic and inductive interaction with the signal.

    “Finally, the Sigma speaker cables are equipped with another patent-pending technology called HARP. Gabriel came up with the idea for this invention while researching current drift and current resonances that occur in speaker cables. The HARP technology is contained in a rectangular module located just prior to each speaker connection and works to diffract current modes, not unlike acoustic treatments used to diffract standing waves (modals) in a listening room. Gabriel says the result is a cable that has greater coherency and is more revealing of the fine detail that can otherwise be obscured by current resonances.

     

    “Now we come to the inevitable question: how do the Sigmas sound? The simple answer is that they sound like nothing I’ve ever heard -- nothing at all, in my experience. The more complicated answer brings me dangerously close to new-age philosophy, where metaphysics overruns good sense. If I tell you they sound like no cables, you have every right to smirk and ask me, "Well, what does that sound like?" The best I can do is offer an analogy and then some specifics.

    “Imagine for a moment that you’ve lived your life wearing surgical gloves. You’ve certainly been able to distinguish and appreciate a great deal of the objects you touch, but once the gloves are off, you discover just how much you’ve been missing. The surface of an apple looked smooth before, but then you discover that it really isn’t. Ice was cold, but nothing prepared you for just how wet and cold it is against your skin. In fact, you’re amazed to learn that ice can actually burn. This is what the Sigmas do: they remove a barrier between you and the utterly visceral, thrilling experience that is live music.

    “So, what is all of this transparency worth? While an entire loom of Sigma cables would cost more than some people’s entire systems, their price point is decidedly lower than what most competing companies are charging for their flagship wires. Still, even the folks at Shunyata are quick to point out that no one should spend this kind of money on interconnects instead of purchasing decent speakers and source equipment. They also say that their Alpha and Delta lines deliver a significant portion of the Sigma's performance for considerably less money. I’m not qualified to offer financial advice, but my experience with the Sigmas proves to me that they can elevate the performance of a very refined system to a level that equals similarly priced components I’ve auditioned. If you are pleased with your current rig and want to see just how high it can fly, auditioning the Sigmas would be a good place to start.

    “Toward the end of my listening, I wrote that the Shunyata Sigmas "open up an unrestricted channel in the signal chain, allowing my speakers to breathe in full, deep breaths of each recording." When it comes to music, it’s often a combination of many small, yet true-to-life elements that can culminate in a performance’s most magical moments. Shunyata’s Zi-Tron Sigma speaker cables, interconnects and digital cables did a remarkable job of revealing those moments from every source and format.” – Vance Hiner
