There is only one place that jitter matters and that is at the DAC, the DAC has a word buffer and does not process a word until it is full, thus variations in bit-timings are averaged out. So far nobody, and I do mean nobody, has found jitter at the levels found in commercial audio products to be ***reliably*** detectable. The poster child for bad jitter is the Oppo HD970 which clocks a massive 4ns of random jitter. However no rigorous test of jitter has found it to be audible below 20ns in music for deterministic jitter (Jitter correlated with the signal giving definite sidebands) or several 100s of ns for random jitter (jitter spread over the spectrum). Jitter just isnt worth worrying about. |

Quantum physicists don't even fully understand the nature of electrons (as they have observed single electrons in multiple places at once), so surely you aren't going to tell me that what flows from one end of your system to the other is going to be identical every single time just because a file is called "bit-perfect". |

This thread was a waste of time, obviously there was a hardware issue or "user error," or both. |

Several open source teams analyzed the code for Microsoft Office and found that it was 40 times larger than it needed to be. |

Paranoid much ? Maybe try taking off the tin foil hat ? This seems to be a case of PEBKAC with a very,very heavy dose of placebo effect. |
Originally Posted by IPodPJ /img/forum/go_quote.gif If timing errors and jitter don't contribute to audio differences, why do people choose I2S over SPDIF if they are both bit-perfect? Why do people buy products from companies like Empirical Audio that re-clock? Why do people buy digital or analog RCA cables that yield different sonic flavors? |
