High Fidelity Cables's Reveal RCA Digital
Digital: SPDIF by High Fidelity Cables
A digital cable carries it's signal as an analog waveform. These analog waveforms differ from normal line level signals, they operate in the Mhz range at very high bandwidth frequencies. The Magnetic Conduction approach to digital signal transfer results in higher slew rate, less jitter, and far superior performance compared to standard cables.
