The Sigma range from Shunyata Research represents the pinnacle of their analogue cables, introducing for the first time their proprietary HARP devices - designed to improve the sonic performance of the cable by acting as a current mode diffraction device, breaking up current resonances in the audio band. This cable also features proprietary ArNi ® VTX, OFE and OCC conductors, and like all Shunyata products it undergoes 4 days of their KPIP processing.

What Shunyata Research say
|
|
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. |

ArNi® wire was designed by Shunyata Research to be the finest quality wire available. It begins with the highest purity of copper and silver metals available, including Ohno (single crystal), PCOCC silver and OFE C0101 conductors. Fluorocarbon dielectrics, usually only found in aerospace applications that have exceptional electrical characteristics including extremely low dielectric absorption, high dielectric strength and superb heat resistance. When used in digital wiring it significantly reduces transient energy storage and release which affects phase noise performance. |
|
|
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 is 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. |
|
|
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. |
 |
Simple crimping, soldering, brazing and screws 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 and cold-welding uses high-energy pneumatic pressure to bond metals. Shunyata Research uses both methods to secure connections that do not degrade over time. |
 |
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 power cables is reduces the perception of dynamic compression and reduces blur and slur of transients. |

Kinetic Phase Inversion Processing 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 cryogenic 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 processor that reduces the need for long burn-in periods and eliminates the effects of cryogenic treatment. Four-days of continuous KPIP™ processing dramatically reduces the sonic ups and downs associated with burn-in, delivering a relaxed and natural presentation. |
Contact Enhancer Option - DeoxIT Gold
To ensure the best possible connection between your system Future Shop recommends the DeoxIT Gold G-Series contact enhancer.
DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.
The benefits of applying DeoxIT gold are:
- Improved Conductivity
- Maintained optimum signal quality
- Reduced wear & abrasion
- Prevents fretting/dendrite corrosion
- Forms a protective anti-tarnishing coating
- Stabilises connections between similar and dissimilar metals
- Reduces arcing, RFI and intermittent connections
We would strongly recommend this option for customers using copper plugs in order to protect them from the adverse effect of oxidisation.
Please select this option from the above ‘Contact Enhancer’ drop-down menu and our engineers will apply the contact solution to your cable connectors prior to shipping.
