The best digital coax cable is no cable: a short and direct BNC to BNC connection. The AudioWise BNC/Coax Adapter Assembly is a three piece assembly of high quality elbow and straight thru adapters. They can be arranged to form a solid articulating digital connection between SRC•DX→DAC, OPTO•DX→DAC, inline DC•BLOCK, LP•FILTER or a coaxial source component to DAC. Differences in connector spacing & orientation are easily accommodated.
The thick nickel plated brass construction of the adapter shell offers 100% shield coverage—much better than braids or foil on standard cables; the inner contact pin is gold plated beryllium copper; the full size coaxial dimension and 75ohm impedance maintains the required electrical characteristics with minimal signal return loss; and the short length avoids any manifestation of antenna effects. Assembly includes 2x elbow (M-F) and 1x straight thru (M-M). Order two for dual-coax connections. Amphenol RF brand.
