I (think I) understand the underlying principle of the test but my simple analogy is it appears to be like testing cars by dropping them three stories up and using that as some real world test metric (along with acceleration, handling, skid tests, braking tests etc)
If our source into the DAC isnt jittery then, in my mind, a DAC that has poor jitter rejection and one that does wont (all other things being equal) sound measurably different (i.e. the one with poor rejection wont be placed into a stressful situation)
I am thinking mainly of an async USB input where the DAC controls the flow so input jitter is in theory low (not considering noise in this question).
So what weighting should be placed on the J-test when selecting a DAC, in comparision to other available metrics.
Wise/knowledgeable comments appreciated.
Thanks,
Peter
