AudioQuest Forest USB - LIGHTNING Cable .75M (2'5")
USB (Universal Serial Bus) Audio:
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 (and for HDMI 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 (jitter) to this information within the data package makes the sound small and flat instead of 3D, harsh and foggy instead of smooth and clear.
SEMI-SOLID CONCENTRIC 0.5% SILVER CONDUCTORS
Semi-Solid Conductors greatly reduce strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications, like USB audio and video. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a 100% silver cable but priced much closer to solid copper cable. This is an incredibly cost-effective way of manufacturing very high-quality USB cables.
HARD-CELL FOAM INSULATION
Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is 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.
