Even though the digital binary bit stream is robust, there are many ways this signal can be corrupted by low quality cables.  Our digital cables are design to have an optimized impedance as per the type of cables: SPDIF ~ 75ohm; USB ~ 90ohm; AES/EBU ~ 110ohm.  The benefit of our cable design, high grade conductors, and materials translate to a digital cable with low jitter and attenuation loss.  These digital cables utilize the same proprietary methods and high quality components as the rest of the Reference II Line to deliver the purest bit stream from your source.
