The insulation which protects wire can create a ghost-like signal that subtly burrs the source audio signal. The scientific term for this is: dielectric absorption and re-radiationΞTRON® is a technology developed by Shunyata Research that prevents this type of signal cable micro-distortion.  It requires a special type of conductor that has two signal paths. An electric-field compensation circuit creates a contra-signal that prevents the insulation from developing a charge.  ΞTRON® ™cables preserve the integrity of the source signal even when using very long cable runs are required.
Transverse Axial Polarizer is a device that interacts with the electromagnetic field generated by the signal traveling along the signal cable. ‌‌TAP affects the behavior of the electromagnetic wave that surrounds the signal cable. In effect, the ‌‌TAP blocks longitudinal-oriented waves while allowing 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. 
ArNi® wire was created by Shunyata Research designed to be the finest quality wire available. It begins with the highest purity of copper available – OFE C101, SPC or Ohno (single crystal). Fluorocarbon dielectrics, usually only found in in the aerospace applications have special electrical characteristics including extremely low dielectric absorption, high dielectric strength and exceptional heat resistance.  When used in digital wiring it significantly reduces transient energy storage and release which affects phase noise performance.
VTX™ — Shunyata Research’s exclusive VTX™ conductors have virtual tube geometry. The core of the conductor is completely hollow minimizing skin effects and random eddy currents.  They are produced using OFE Alloy C0101 - the highest grade of copper with a minimum 99.99% purity and a conductivity rating of 101% IACS.
High Purity Conductors - 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 which comes with a written certification of purity.
Welded Connectors - 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 which will not degrade over time.
Kinetic Phase Inversion Processing
Developed by Caelin Gabriel after years of research. KPIP addresses the underlying causes of various effects such as burn-in, wire directionality and the effects of cryogenic treatment. Caelin 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.
