About the QED Performance Digital Audio Coaxial Cable
Digital audio looks simple, but the signal still needs correct timing and protection from interference, or you risk jitter and degraded sound. This cable is made to the proper 75Ω impedance for coaxial S/PDIF, which keeps reflections down.
A solid 99.999% oxygen-free copper conductor sits in a foamed polyethylene dielectric, inside dual screening of aluminium Mylar foil and tinned copper braid. The plugs are gold-plated RCA/phono and the jacket is flexible stone grey TPE.
It is part of QED’s Performance range. Use it from any source with a coaxial digital output to a DAC, receiver or amplifier with a coaxial input.
