[QUOTE="sajunky, post: 1054683, member: 22308"] There is no impedance mismatch when: 1. Source driver and a receiver impedance matches cable impedance. 2. A right connector is used. There are two two types of BNC connectors: 50 and 75 Ohm. They look similar, but can be visually identified by a professional. S/PDIF coax specification is very lose and electrically inferior to the AES/EBU coax type AES-3id. Driver impedance matching is also not followed in many implementation. In the end, results are unpredictable. [/QUOTE]
