I've seen this term thrown around quite a bit. My limited understanding of it is that it represents the deviation from perfect accuracy in reading the digital data which could theoretically (in this application) lead to some inaccuracies in sound reproduction. Is this correct? What would the difference be on a technical level between ripping a CD to FLAC and using a DAC versus using a CD player or transport/DAC combination? Any advantage/disadvantage to going one way versus another? Any real-world night & day difference which can be heard when going for one setup versus another?
