Alpha v2 AES/EBU

The transmission of high-speed digital signals differs significantly from that of audio frequency signals, necessitating a distinct knowledge base and design criteria. While audio cable signal transmission is guided by the principles of inductance, capacitance, and resistance, high-speed digital signals adhere to the principle of transmission line theory. The efficacy of a transmission line is contingent upon the cable's characteristic impedance, with specific cable types requiring precise characteristic impedances for optimal performance — for example, cable TV coaxial cables typically maintain 75 ohms, whereas test equipment cables necessitate 50 ohm cables. In modern audio and entertainment systems, multiple digital connections may coexist, each potentially possessing differing characteristic impedances.

Though characteristic impedance plays a crucial role in digital cable performance, our research underscores the significance of the cable's construction precision in determining its effectiveness. Despite superficial similarities between digital and analog cables, such as the possibility of terminating S/PDIF cables with RCA connectors akin to analog interconnects, the use of analog interconnects as substitutes for digital cables is ill-advised due to the lack of correct characteristic impedance, resulting in compromised performance.


Shunyata Research digital cables are produced using a ‌Precision Matched Z (‌‌PMZ) concept. 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’. (Note: Z means impedance)
‌‌ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest purity of copper available – OFE C10100 or Ohno (single crystal). Then it is formed in virtual hollow tubes eliminating skin effects and eddy current distortions. In addition, the wire undergoes our proprietary KPIP™ process.
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-mode 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


Shunyata Research’s proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP™ processing to dramatically reduce burn-in time and significantly improve sonic performance, delivering a relaxed and life-like presentation.

PMZ Connectors

Pulse timing is critical to digital transmission accuracy.  It is critical that a digital connector’s impedance precisely matches 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 is precisely matched for a seamless component-to-component connection.
