AudioQuest RJ/E Diamond
The AudioQuest RJ/E Diamond represents the ultimate expression within AudioQuest’s audiophile Ethernet cable lineup. Specifically engineered for absolute reference-level streaming and network audio systems, the Diamond combines ultra-pure materials, advanced proprietary technologies, and extremely sophisticated construction to deliver virtually flawless digital transmission.
In modern audio systems, high-resolution streaming has become one of the primary music sources. Streamers, network DACs, music servers, and platforms such as TIDAL, Qobuz, and Roon rely on exceptionally stable and low-noise Ethernet transmission to achieve their full sonic potential.
The AudioQuest RJ/E Diamond has been developed to minimize jitter to the greatest possible extent, reduce RF noise, and preserve the temporal integrity of the digital signal — resulting in more natural, transparent, and three-dimensional reproduction.
Its construction features solid Perfect-Surface Silver (PSS) conductors of extreme purity. PSS technology dramatically reduces distortion caused by grain boundaries present in any metallic conductor, providing exceptional clarity, smoothness, and precision.
Solid-core conductors also eliminate distortion generated by strand interaction, significantly improving focus, cleanliness, and sonic stability.
The high-density solid polyethylene insulation maintains extremely precise geometry between twisted pairs, reducing loss and minimizing dielectric-induced phase distortion.
One of the most advanced technologies incorporated into the RJ/E Diamond is AudioQuest’s DBS (Dielectric-Bias System). This system creates a constant electrostatic field that polarizes the cable’s dielectric, reducing energy storage and minimizing non-linear time delays. The audible result is an exceptionally silent background, a more stable soundstage, and clearly enhanced micro-detail and dynamic contrast.
Precision RJ45 connectors provide full shielding coverage and strain relief, ensuring stable transmission and exceptional immunity to electromagnetic and radio-frequency interference.
Compliant with Cat 7 specifications, the AudioQuest RJ/E Diamond supports Ethernet transmission up to 10 Gigabit and is intended for the highest-level audiophile systems where every detail produces clearly audible differences.
Like all AudioQuest cables, the Diamond is directional. Arrows printed on the cable indicate the optimal signal flow direction to minimize induced noise and optimize sonic performance.
The final result is a more organic, silent, precise, and three-dimensional presentation, capable of extracting the maximum performance from any high-end streaming system.
