PMZ — Shunyata Research digital cables are produced using a Precision Matched Impedance cable geometry. 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.
(Z definition = impedance)
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.

CMODE — Common-node noise is different than differential noise and is much more difficult to measure and eliminate. For the purest signal possible, Shunyata Research has developed a CMODE filter that effectively reduces common-mode noise without introducing the sonic compression effects associated with conventional filters. It reduces high-frequency noise distortion while delivering an analog ease and palpable background silence that closes the gap between digital and analog systems.
— Reduces common-mode noise.
PMZ Connectors — Pulse timing is critical to digital transmission accuracy. It is critical that a digital connector’s impedance precisely match the cables's characteristic impedance. A mismatched connector will create signal reflections which increases digital jitter or phase noise. A 50-ohm cable requires a 50-ohm termination — not the commonly used 75-ohm connector. Shunyata Research is careful to ensure that every cable and connector are precisely matched for a seamless component to component connection.
Kinetic Phase Inversion Processing
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.
