"I'd sum up these differences as more. You get an increasingly large sound picture as you move up the line, greater differentiation between sonic elements, and a greater sense of clarity. Again, these changes are not subtle or slight. I did not have to do any sort of special listening to special tracks, put on a lab coat, or comb my thinning hair in a particular manner. All I had to do was sit and listen and the changes I've described were readily apparent."
The Diamond is a top-grade Ethernet Cable which is the result of a lifetime's research by AudioQuest made from the very best materials available. This really is a 'money no object' cable for the dedicated Hi-Fi enthusiast that has extended into a world of digital audio sources.
By extending the thought process of quality cabling from a server, PC or Media streamer to the router, further detail can be realised and restrictive shackles loosened. AudioQuest's Diamond RJ/E is a directional Ethernet cable made with the same hallmark materials, philosophy, care and attention that is applied to all their interconnects, whether it's an entry level introduction to hi-fi or a died-in-the-wool music connoisseur. Another upgrade with Diamond is a complete plug redesign, opting for an ultra-performance RJ45 connector made from silver with tabs that are virtually unbreakable. The plug comes with added strain relief and firmly lock into place ensuring no critical data is lost.
The beating heart of the AudioQuest Diamond are the Solid 100% Silver Perfect Surface conductors where raw silver is processed by drawing through at a much slower speed than normal to create an ultra-smooth surface area free of indents and grooves. Insulation is also a commodity that slows down a signal so AQ have featured their Dielectric-Bias System (DBS); a self-generated stable electrostatic field which reduces energy storage and non-linear time delays to a minimum.
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.
Noise, in the form of RF energy, is the mortal enemy of good sound. Our environment is more contaminated with RF than ever before due to the huge proliferation of RF radiating devices like computers and mobile phones. Traditionally, RF energy is routed to ground through the use of a 'shield" consisting of either a braided metal or foil. This 'draining' of RF to ground causes a modulation of the ground plane, which in turn causes a form of signal modulation. 100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AudioQuest's Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment’s ground plane.
All audio cables are directional. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. Arrows are clearly marked on the connectors to ensure superior sound quality. For best results have the arrow pointing in the direction of the flow of music. For example, NAS to Router, Router to Network Player.
Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Solid High-Density Polyethylene Insulation ensures critical signal-pair geometry while minimizing insulation-induced phase distortion.
All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest’s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.
