Such tests would be almost meaningless as it is the interaction between sender (output), cable and receiver (input) that decides the overall performance. Technical reason is very simple: 1. The digital data stream (SPDIF) includes timing information. 2. Receiver chips have so far failed to supress all variation in this timing information -instead letting through a lot of it. This variation is called "jitter". 3. The link (coax or optical) influences the timing information. 4. Modern ASRCs (asynchronous sample rate converters) may make matters worse by embedding jitter in the new, converted, datastream -thus making any downstream reclocking schemes ineffective in rejecting link jitter.
