ALPHA-X DIGITAL CLOCK-50 CABLE

REFERENCE-LEVEL S/PDIF DIGITAL CONNECTIVITY WITH EXCEPTIONAL TIMING, CLARITY & MUSICAL REALISM
The Shunyata Research Alpha-X Clock-50 Digital Cable is a reference-grade balanced digital audio cable engineered to preserve signal integrity between high-end digital audio components. Designed for 50-ohm Clock-50 connections, Alpha-X combines Shunyata Research's proprietary TAPc™, CMode™, KPIP v2™, PMZ, and fluorocarbon dielectric technologies to reduce cable-induced jitter, electromagnetic interference, and high-frequency noise.
The result is a cleaner, more precise digital signal with improved timing, dimensionality, low-level resolution, and musical coherence. For audiophiles seeking uncompromising performance from a digital transport, DAC, music server, streamer, or other S/PDIF-equipped component, Alpha-X provides a highly refined connection engineered for reference-level digital audio systems.
ENGINEERED TO REVEAL THE FULL POTENTIAL OF DIGITAL AUDIO
Digital audio systems can be affected by subtle distortions introduced by the interconnect itself. Cable-induced jitter, electromagnetic interference, common-mode noise, and dielectric effects can compromise timing and phase accuracy, ultimately affecting the realism of reproduced music.
The Alpha-X Clock-50 cable is engineered to address these factors at the cable level.
Its precision construction and proprietary technologies work together to preserve the integrity of the digital signal, allowing your DAC and digital source components to perform closer to their full potential.
The result is an exceptionally natural and dynamic presentation characterized by:
- Greater timing accuracy
- Improved musical coherence
- Lower perceived noise
- Enhanced low-level resolution
- More precise imaging
- Greater depth and dimensionality
- Cleaner transient detail
- More natural dynamics
50-OHM DIGITAL CLOCK CABLE FOR HIGH_END AUDIO
The Alpha-X S/PDIF is specifically engineered as a 50-ohm balanced digital audio cable, making it ideal for professional and high-end consumer digital audio equipment equipped with 50 ohm digital connections.
Its twinaxial construction uses OCC copper conductors and a 100% foil shield, while the precision-controlled impedance helps maintain signal integrity throughout the digital connection.
Alpha-X is an ideal choice for connecting:
- Digital transports to DACs
- Music servers to DACs
- Digital preamplifiers
- Professional digital audio equipment
- High-end CD transports
- Reference digital sources
- S/PDIF-compatible streaming components
Alpha-X is the perfect choice for those that demand absolutely uncompromising levels of performance.
TECHNOLOGY
![]() | TAPc (Transverse Axial Polarizer) is a patent-pending technology that couples to the electromagnetic fields surrounding electrical or signal conductors. TAPc behaves like a polarizer, passively reducing electromagnetic distortion that presents as a type of glare on sound or images. The sonic impact of TAPc is unmistakable. There is a profound drop in perceived noise floor, effortlessly portrayed dynamics and an immediate improvement in the rendering of timing and coherency in sound. These performance elements are unique to TAPc and remain unaddressed by competing technologies of any kind. Even casual listeners can recognize the effect TAPc has upon first listen. Results are consistent across a wide range of components and systems. Essentially, the TAPc modules act as force multipliers, elevating the listening experience to levels many would not have thought possible. |
![]() | KPIP v2™ Shunyata Research’s proprietary Kinetic Phase Inversion Process includes four days of continuous KPIP v2™ processing which refines conductor metals at the atomic level. This dramatically reduces burn-in time and significantly improves sonic performance, delivering a relaxed and life-like presentation. When compared to the original process, KPIP v2™ represents a dramatic performance upgrade on par with a component-level upgrade. |
![]() | Shunyata Research produces select cables 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. (Note: Z means impedance) |
![]() | 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. |
![]() | 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 audio and power cables is reduces the perception of dynamic compression and it improves sonic low-level resolution and clarity. Crystal clear transient detail. |
