what's this?
SPEAKER CABLES:

A quantity of 2 means you will receive a pair of speaker cables e.g. for your front left and front right speakers. By entering a quantity of 1, you will get a cable for a single speaker e.g. centre speaker and this option also enables you to vary the length (and termination) of your cable for each speaker.

OTHER CABLES:

A quantity of 1 means you will receive a single cable in the case of aerial, satellite, subwoofer, digital coaxial & optical cables and a pair of cables in the case of 2 rca to 2 rca analogue audio cables.

NON-CABLE PRODUCTS:

A quantity of 1 means you will receive 1 of the specified products.

What Shunyata Research say

High-speed digital transmission is very different from audio frequency signal transmission and requires a different knowledge base and design criteria. Audio cable signal transmission is governed by the principles of inductance, capacitance, and resistance. By contrast, high-speed digital signals are governed by a principle known as ‘transmission line theory’.

The performance of a transmission line is governed by the characteristic impedance of the cable. Certain types of cable require a specific characteristic impedance to achieve optimal performance — for instance, cable TV coaxial cables are 75 ohms, while test equipment cables require 50 ohm cables. Modern audio and entertainment systems may have multiple digital connections, each with potentially different characteristic impedances.

While the characteristic impedance is a critical factor in the optimal performance of digital cables, our research also indicates that the precision with which a digital cable is constructed has a significant impact on its performance.

Superficially, digital cables may look the same as analog cables. For example, a S/PDIF cable can be terminated with RCA connectors, much like analog interconnects. Because the terminations appear the same, analog interconnects could be used as a substitute for a digital cable; but since it has not been designed with the correct characteristic impedance, the performance will suffer.

 

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.
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.
Shunyata Research’s exclusive ‌VTX™ conductors are made in the shape of virtual tubes. The core of the conductor is completely hollow minimizing skin effects and random eddy currents. They are produced using OFE Alloy-101.
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.

 

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.

 

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.
