AudioQuest Pearl RJ/E Ethernet Cable (1.5m Single)

The AudioQuest Pearl RJ/E is the entry-level model in AudioQuest's RJ/E Ethernet cable range, applying the same directional signal-path thinking and noise-dissipation technology that the brand uses across its analogue and digital cable lines to the demands of wired network connectivity. Where a standard Cat Ethernet cable treats the network connection as a purely functional data link, the Pearl RJ/E is engineered with audio streaming in mind — addressing the radio-frequency interference and signal-path distortion that AudioQuest argues can degrade the performance of networked audio systems.

Conductors and Geometry

The Pearl RJ/E uses solid Long-Grain Copper (LGC) conductors throughout. AudioQuest favours solid-core construction because it eliminates the strand-interaction distortion that arises when signal currents travel through the boundaries between individual strands in a conventional stranded conductor. The long-grain copper refinement extends this principle further: the crystal grain boundaries within the metal itself are reduced in number, lowering the number of material transitions the signal must cross. AudioQuest describes the insulation as Geometry Stabilizing Solid High-Density Polyethylene — selected and optimised for its ability to maintain precise conductor geometry within the cable structure and minimise dielectric energy absorption, both of which AudioQuest states help preserve dynamics and reduce distortion.

Noise-Dissipation and Shielding

The Pearl RJ/E includes Level 1 Noise-Dissipation — AudioQuest's term for the first tier of their RF noise-handling system, designed for the most efficient dissipation of radio-frequency noise that can accumulate on the cable's shield and degrade audio performance. The connectors are gold-plated nickel with 100% shield coverage, which AudioQuest states further reduces distortion while complementing the noise-dissipation system. The cable supports 10-Gigabit Ethernet over 100 metres of copper cabling, making it equally suited to music streaming racks, home cinema installations, and general high-speed network infrastructure.

Directionality

Like all cables in the AudioQuest RJ/E range, the Pearl is manufactured and terminated in a specific direction, with arrows on the connectors indicating the recommended signal flow from source to destination — for example, from NAS drive to network switch, or from router to network streamer. AudioQuest designs directionality into their cables based on the premise that the signal-path geometry performs optimally when signal travels in the direction in which the cable was drawn during manufacture.
