Jitter with closed circuit digital audio signals matters under two circumstances. One is during transport of a bitstream should the jitter be so severe as to provoke actual bit error. This practically is never going to happen with any competently designed home digital audio system. The other circumstance is during domain conversion, meaning from analog-to-digital and from digital-to-analog. This is where all the concern is for home audio playback.Ripping a digital audio signal file from one medium to another doesn't fall under either of the above two circumstances. So long as the bits are all accurately transcribed the stored signal is considered perfect. Domain conversion based jitter arises as the stored signal data is clocked in to the D/A unit. The local (re)generation of the key conversion clock signal has a number of possible methods, PLL, FIFO, NCO, DAC as clock master, etc.
