Clarus Crimson AES EBU 2m
Overview
The Clarus Crimson AES EBU is a high-end digital audio cable designed for discerning audiophiles. Handcrafted in the United States, it combines cutting-edge technologies with traditional craftsmanship to deliver optimal audio signal transmission. This AES/EBU cable stands out for its unique variable geometry architecture and sophisticated shielding, offering remarkable sound neutrality at a relatively accessible price in the high-fidelity world.
Advanced technologies serving music
The Crimson AES EBU exclusively uses PCOCC copper (Pure Copper by Ohno Continuous Casting), a Japanese technology renowned for its exceptional purity. This continuous casting process eliminates impurities and junctions between copper crystals, enabling smoother and distortion-free signal transmission. The PCOCC conductors of the Crimson AES EBU have a gauge of 1.29 mm, providing a generous cross-section for optimal digital signal transmission.
The use of PCOCC copper significantly reduces skin and proximity effects, two phenomena that can degrade signal quality in conventional cables. This material purity translates into increased transparency and better sound definition, particularly noticeable on high-end audio systems.
A unique variable geometry architecture
The major innovation of the Crimson AES EBU lies in its patented variable geometry architecture. Clarus has developed a triple-balanced configuration using three different types of conductors, each optimized for a specific frequency range:
- For low frequencies: multiple solid conductors
- For mid frequencies: a single flat conductor
- For high frequencies: multiple spiral ribbon conductors
This tailored approach adapts the cable’s geometry to the propagation characteristics of each frequency range. Low frequencies benefit from the stability of solid conductors, mids take advantage of the low inductance of the flat conductor, while high frequencies are carried by spiral ribbons that minimize skin effect.
Each conductor is individually insulated to limit unwanted interactions. This meticulous insulation, combined with the variable geometry, helps preserve the integrity of the digital signal throughout its transmission.
Sophisticated shielding against interference
The Crimson AES EBU features a triple-layer shielding system designed to provide maximum protection against external electromagnetic interference. This shielding consists of:
- An independent aluminum/Mylar protective layer
- A thick braided copper shield
- An antenna/drain shield
An interesting feature of this system is the disconnection of the shielding on the receiver side. This technical trick prevents the formation of ground loops, which can cause noise and distortion. The antenna/drain shield is only connected on the source side, ensuring effective dissipation of captured interference without creating an undesirable return path.
This meticulous shielding approach contributes to the purity of the transmitted signal, a crucial aspect for a digital AES/EBU cable tasked with carrying data sensitive to disruptions.
The pursuit of sound neutrality
Clarus’ philosophy with the Crimson AES EBU is clear: to aim for absolute sound neutrality. The goal is not to color or alter the sound but to transmit the digital signal as faithfully and transparently as possible. This approach respects the integrity of the work of artists and sound engineers.
The combination of PCOCC copper, variable geometry architecture, and sophisticated shielding contributes to this neutrality. The result is a cable that neither adds nor subtracts anything from the original signal, allowing the subtlest nuances of music to be fully expressed.
This neutrality translates into a precise and well-defined soundstage, natural timbres, and preserved dynamics. The Crimson AES EBU excels particularly in reproducing fast transients and micro-details, crucial elements for an immersive and realistic listening experience.

Frequently Asked Questions
What is the difference between the Crimson AES EBU and a standard AES/EBU cable?
The Crimson AES EBU stands out for its use of ultra-pure PCOCC copper, patented variable geometry architecture, and sophisticated triple shielding. These features enable more precise signal transmission and reduced susceptibility to interference compared to a standard AES/EBU cable, resulting in better sound quality on high-end systems.
How does the Crimson AES EBU compare to Clarus' higher-end Aqua range?
The Crimson AES EBU shares many technologies with the Aqua range, including the use of PCOCC copper and variable geometry architecture. The main difference lies in the quality of materials used for insulation and shielding, as well as the complexity of the conductor geometry. The Aqua offers slightly superior performance, particularly noticeable on ultra-high-end audio systems.
Is the Crimson AES EBU compatible with high-resolution audio?
Yes, the Crimson AES EBU is fully compatible with high-resolution audio formats. Its meticulous design and effective shielding allow it to transmit digital signals up to 192 kHz / 24 bits, or even beyond, without loss. It is therefore perfectly suited for modern audio systems capable of playing high-resolution files or DSD.
