Cinnamon USB-A > B High-Definition Digital Audio Cable Cinnamon USB features high-purity 1.25% Silver conductors and a Metal-Layer Noise-Dissipation for the most efficient dissipation of radio-frequency noise. Solid conductors prevent strand-interaction, a major source of dynamic distortion in cables. 1.25% Silver-Plating is applied to AudioQuest’s Long-Grain Copper (LGC) conductors to improve Noise-Dissipation. Metal-Layer Noise-Dissipation shields noise effectively, absorbing and reflecting most RFI before it reaches the ground layer. Hard-Cell Foam's high air content minimizes energy absorption for clearer sound. All conductors controlled for RF-noise directionality.
