What customers say
High end audiophiles view the AudioQuest Diamond RJ/E Ethernet Cable as an endgame component delivering significant sonic improvements. The core feedback centers on enhanced clarity, a blacker background, and superior soundstage depth. Users report the cable removes digital noise, allowing subtle musical textures to emerge with greater realism. Build quality, utilizing PSS conductors and the DBS system, is universally praised, reinforcing its meticulous engineering. While performance gains are lauded, the extreme price point tempers the value perception for most consumers. Dedicated purchasers, however, find the cost justified by the perceived leap in sonic purity and resolution, confirming it as a benchmark for resolving systems.
Know before you buy
While standard cables use copper, the Diamond RJ/E features solid 100% Perfect-Surface Silver conductors. This material choice, combined with advanced noise-dissipation and dielectric-bias systems, is designed to reduce signal distortion and jitter that can affect high-end audio streaming.
Yes, AudioQuest tests every conductor for correct directionality. Following the arrows on the cable jacket ensures that the signal path is optimized for the lowest possible noise, which is critical for maintaining signal integrity in sensitive audio systems.
This cable is engineered specifically for high-fidelity audio applications where precision and low latency are paramount. While it supports 10-Gigabit speeds, you will not notice a difference in general web browsing or file downloads compared to a standard high-quality Ethernet cable.
The DBS creates a stable electrostatic field that saturates and polarizes the cable's insulation. This minimizes the time-delay effects caused by the dielectric, resulting in a cleaner, more dynamic sound by ensuring the signal remains as pure as possible.
The 3-layer carbon-based system acts as a shield to prevent Radio Frequency Interference (RFI) from reaching the signal conductors. By absorbing this external noise, the cable prevents it from being converted into audio distortion.
Yes, it uses standard RJ45 connectors and is fully compatible with any device that accepts a Cat 7 Ethernet connection, such as high-end streamers, DACs, or network switches.
