Cinnamon USB-A to Micro B 2.0SEMI SOLID CONCENTRIC 1. 25% SILVER CONDUCTORS Semi Solid Concentric conductors greatly reduce strand interaction distortion and reduce jitter. Silver plated conductors are excellent for very high frequency applications, like USB audio. 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 solid silver cable, but
