The Audioquest RJ/E Pearl network cable is a high-end connectivity solution for discerning enthusiasts of music and video streaming. Designed with premium materials, this Category 7 Ethernet cable delivers outstanding performance with throughput of up to 10 Gbps over a distance of 100 meters. Its carefully engineered design with Long-Grain Copper (LGC) conductors and gold-plated connectors ensures optimal digital signal transmission, essential for fully enjoying your high-definition audio and video content without latency or degradation.
The Audioquest RJ/E Pearl cable stands out for its meticulous design using carefully selected materials. The Long-Grain Copper (LGC) conductors are the core element of this cable. Unlike standard copper, LGC copper has a smoother surface with fewer imperfections and irregularities. This characteristic enables smoother signal transmission and significantly reduces distortion, which is particularly important in high-frequency applications such as high-resolution audio streaming.
The solid high-density polyethylene insulator with a geometry stabilizer also plays a crucial role. This technology keeps the conductors perfectly aligned and spaced, ensuring constant impedance along the entire length of the cable. This geometric stability is fundamental to preserving the integrity of the digital signal and minimizing transmission errors that could affect audio or video quality.
The outer PVC jacket with CMG rating (compliant with CL3 and FT4 standards) and its distinctive black and gray striped design is not just aesthetic. It provides excellent mechanical protection while meeting safety standards for residential and commercial installations. This compliance with safety standards allows you to use this cable in various configurations, including in-wall or ceiling runs, if necessary.
The Audioquest RJ/E Pearl cable stands out for its exceptional performance as a Category 7 Ethernet cable. This classification enables data transfer rates of up to 10 Gbps over a distance of 100 meters—ten times more than a standard Category 6 cable limited to 1 Gbps. This high transfer capacity is especially valuable for demanding applications such as high-resolution music streaming, 4K or 8K video, and online gaming where latency must be minimized.
Beyond raw technical specifications, this cable excels at reducing jitter (digital timing variation). This phenomenon, often overlooked in standard network setups, can have a significant impact on perceived audio quality. Jitter manifests as small timing variations in the transmission of digital data, creating audible micro-distortions in the form of hardness or tension in the sound. Thanks to its optimized design, the Pearl RJ/E minimizes these undesirable effects, delivering a more natural and relaxed sonic presentation.
The gold-plated nickel RJ45 connectors are another major asset. Gold plating ensures excellent electrical conductivity while protecting against oxidation and corrosion, thereby guaranteeing a reliable, durable connection. The 100% shielding of these connectors, combined with the cable’s overall build quality, provides optimal protection against external electromagnetic interference that could compromise signal integrity.
The Audioquest RJ/E Pearl cable fits into many high-end audio and video setups. It is particularly recommended for connecting network components critical to sound quality, such as a NAS (Network Attached Storage) holding your music library to a router, or a router to a network player or audio streamer. In these configurations, the quality of the network connection directly influences the system’s overall performance.
This cable is also perfectly suited for connecting demanding home theater equipment such as 4K/8K TVs, UHD Blu-ray players, next-generation game consoles, or AV receivers with network features. The cable’s ability to maintain signal integrity over its 5-meter length lets you position your devices optimally without compromising performance.
The Pearl RJ/E’s compatibility is universal with all equipment using a standard Ethernet connection. However, its benefits will be particularly noticeable with high-fidelity audio devices such as network DACs, audiophile streamers, or high-end audio servers. These components, often equipped with precise internal clocks and sophisticated audio circuits, are more sensitive to the quality of the incoming network signal and will fully capitalize on this cable’s superior characteristics.
The Audioquest RJ/E Pearl cable has clearly marked directional arrows on its connectors. These arrows should point in the direction of the musical data flow. For example, if you are connecting a NAS (source) to an audio streamer (destination), the arrow should point from the NAS to the streamer. For a more complex chain, such as NAS → router → streamer, always follow the direction of data flow at each segment.
The impact of the Audioquest RJ/E Pearl cable on sound quality depends on several factors, including the quality of your equipment and your listening sensitivity. The most noticeable improvements typically manifest as better definition of sonic details, a more precise soundstage, and more natural timbre reproduction. High-end systems with quality DACs and amplifiers will reveal these differences to a greater extent. The improvement will be particularly perceptible when listening to high-resolution music where signal integrity is paramount.
CAT7 cable offers higher bandwidth (up to 600 MHz versus 250 MHz for CAT6) and supports data rates up to 10 Gbps over 100 meters, whereas CAT6 is limited to 1 Gbps at that distance. CAT7 also features more comprehensive shielding, with each wire pair individually shielded in addition to overall cable shielding. This enhanced protection against interference is particularly beneficial for sensitive audio applications. CAT5e, by contrast, is limited to 100 MHz and 1 Gbps, with significantly less shielding.
The Audioquest RJ/E Pearl cable is perfectly suited to demanding professional applications. Its compliance with CMG (CL3 and FT4) standards makes it suitable for commercial and professional installations. It is particularly recommended for recording studios, audio mastering facilities, professional screening rooms, or any environment where network signal quality and reliability are paramount. Its ability to minimize jitter and interference makes it a wise choice for critical professional audio applications.

It seems to me that this internet cable, connected between an Atoll SDA 300 amp and my box, stabilizes the speed much better and provides a better result.
