In the world’s finest systems, even the smallest amount of signal degradation will result in inferior performance and the digital signal from your source is highly critical.  Our digital cables are design to have an optimized impedance as per the type of cables: SPDIF ~ 75ohm; USB ~ 90ohm; AES/EBU ~ 110ohm.
Furthermore, the connector and cable design are optimized to achieve the least amount of losses (ie. insertion loss and return loss) for the digital signal transfer between the transport/server and DAC. These interconnect incorporate Ultra Line technology including our proprietary alloy made with precious metals to deliver the purest signal. The benefit of our cable design, high grade conductors, and materials translate to a digital cable with low jitter and attenuation loss.
