AudioQuest - Diamond - USB-A to Lightning Digital Audio Cable (Single)

AudioQuest's Diamond Lightning USB cables use Solid 100% Perfect-Surface Silver (PSS) conductors, which completely eliminate strand interaction, one of the biggest sources of distortion in cables, for clearer, more dynamic and involving sound. 

Superior conductor metals minimize distortion by having fewer grain boundaries and less impurities at those boundaries. Hard-Cell Foam insulation helps maintain critical data transfer. Of course all AudioQuest Diamond Lightning USB cables are terminated so as to honor the directionality inherent in all analog and digital audio cables. 

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 that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

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 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.

For many applications, the speed of digital communication is important. Most visibly, “speed” is about transferring large files as quickly as possible, or carrying enough data for an HD video. For USB audio, “speed” is critical not because of how-much-how-fast, but because time relationships within a digital stream are critical to the reconstruction of the analog wave form that brings information, music and joy to our ears. Time-based damage to this information within the data package makes the sound small and flat instead of 3D; harsh and foggy instead of smooth and clear.
