AudioQuest 4.9 Feet Diamond USB A To B Digital Internonnect Cable - USBDIAMONDA2B1POINT5M
In 1982 Sony gave us "Perfect sound forever," along with the attitude that, "it's just digital, so all CD players sound the same." That was disproved and qualitative differences between players became accepted truth. Next came separate transport and DAC combos, which brought with it the attitude that "all S/PDIF digital audio cables sound the same..." until that too became disproved. Now the frontier has moved once again. Is digital audio really just ones and zeros? We don't believe so, and once you've had a chance to listen to Diamond USB, you won't think so either...
Features
- Solid Perfect-Surface Silver (PSS) Conductors
Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Perfect-Surface Silver (PSS) is AudioQuest's highest-quality metal. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers. - Hard-Cell Foam Insulation
Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our more affordable Bridges & Falls cables, and is nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable's conductors to maintain a stable relationship along the cable's full length, producing a stable impedance character and further minimizing distortion. - All Conductors Controlled For Rf Noise Directionality
- Carbon-Based 3-Layer Noise-Dissipation System (NDS)
It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground. - Dielectric-Bias System With Radio Frequency Trap
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements.

Frequently Asked Questions
-
The conductors use Solid Perfect-Surface Silver (PSS), which is high-purity silver with minimal distortion. This material reduces harshness and increases clarity compared to other metals like copper. Solid conductors also prevent strand interaction, which can cause distortion.
-
The cable uses Hard-Cell Foam Insulation (HCF), which is nitrogen-injected to create air pockets. This reduces energy absorption and release that cause distortion. The insulation also maintains stable conductor geometry, ensuring consistent impedance and minimal signal distortion.
-
The Carbon-Based 3-Layer Noise-Dissipation System (NDS) uses alternating layers of metal and carbon-loaded synthetics to absorb and reflect radio frequency interference (RFI). This system prevents noise from modulating the equipment's ground reference, which reduces signal distortion.
-
The Dielectric-Bias System (DBS) applies a bias to the insulation dielectric to minimize energy absorption and release that cause phase shifts and delays. An integrated radio frequency trap ensures that RFI does not induce noise into the signal conductors, maintaining a clean and time-accurate audio signal.
-
The cable measures 1.5 meters (approximately 4.9 feet) and features a sleek black finish, which visually complements most setups while providing high-quality construction.
