interesting view posted by Doug on Oade:
"No modern PCM recorder is bit accurate, no over sampling A/D converter can possibly be bit accurate, nature of the beast ! You must go DSD if you want all the data.
Is the digital input bit accurate ? Depends on the design, if it is able to use the recovered clock from the dig in for the A/D converter, it could be. Odds are the digi in is a resampler on any 4 channel box that has both analog and digi ins that will stay in sync with each other. If it does resample, the more crucial question is will the digi out pass the original data and clock or the resampled data. I do not mind a HQ resampler for a mastering device but if it resamples within a daisy chain, I would not want to be the last guy in that chain.
