Unlike other ground wires that act as radio-frequency antennas, AudioQuest Black Hole GroundGoody prevents hum while efficiently dissipating radio-frequency noise. AudioQuest Black Hole GroundGoody uses premium conductor materials — AudioQuest’s 6% Silver over Long-Grain Copper — that are controlled for direction and cold-welded to Direct-Silver Plated #10 size spade lugs. Further, AudioQuest Black Hole GroundGoody employs a Carbon RF-Trap comprising conductive PVC to aid RF-Noise-Dissipation.

AudioQuest Digital Coax cables are designed to minimize distortion across an extremely wide bandwidth. 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 HD video. For Digital Coax 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 waveform 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.

AudioQuest designed the Cinnamon OptiLink to provide a distortion-free connection between your digital audio components — CD players, Blu-ray or DVD players — to A/V receivers, DACs, and even some sound bars. The core of the Cinnamon is a finely polished, low-distortion polymer fiber conductor that minimizes signal loss and jitter (time-based distortion). The cable has full-size Toslink connectors at each end, reinforced by a brass ferrule, which helps ensure ideal light transmission for the highest quality sound.
