Skunk, Patrick is referring to other issues with digital clocking that can and will degrade the final output of the audio system. Jitter is a short term variation in the frequency of the clock used to time the digital signals, drift is a longer term variation, but they all contribute to jitter and thus degradation. The ideal way to clock digital audio systems (and the way it is done in most pro setups) is to have a single master clock (with several replicated, low jitter copies of that master clock signal available) and then feed a clean instance of this master clock to each of the components; transport or SB, processing equipment, DAC, digital amps etc. With this technique, by and large, the jitter performance of the system is dictated by the quality of the master clock (some master clocks quote 0.1ppm as typical jitter figures). If you don't have this master clock setup the next best thing would be to have the DAC generate a low jitter clock and then provide an external clock for the transport or SB.
