Hello Steve, long time no see, been in prison ?
Steve, you are being a little bit disengenuous here. You know full well that there are different variations of jitter and only signal-correlated jitter has been empirically tested to be detected at levels of about 20ns (Benjamin and Gannon) in music which is 100x the level of that found in a competent DAC (200ps) or 10ns as pure tones at 17K, random jitter however has been empirically tested to be undetectable at up to 250ns (Ashihara et al) which is 1250x worse than a competent DAC, please get your facts right![]()
The tests are silly at best. First there is no means to calibrate "injected" jitter, where is the ASTM? Is random jitter ever encountered from a transport in a level worth discussing?, its the deterministic jitter that must be studied deeper. So we have this one stupid deterministic jitter "study", but its a fact that a pure 17khz sine wave doesn't exist in nature. The only time we ever here one is a hearing test, pretty foreign to the ears and a pretty poor test my freind, hell most people can barely hear 17khz, there is no music up there. No one can unequivically say that a multimillion dollar transport industry and hundreds of thousands of customers are experiencing mass auditory jitter hallucinations. That stance borderlines on the schizophrenic ....
