and also,
"the differences in how the two formats sound are mostly subjective, meaning they're more or less a matter of opinion, as is everything relating to sound and music. the concepts of what sounds 'better' or 'worse' are wholly subjective concepts and vary from person to person."
and
"yes, the involvement of protools *does* necessarily mean you're now 'digital'. and all digital recordings are at some point analog, meaning that sound itself is an analog phenomonon, and the vast majority of microphones are analog devices, so when talking about 'digital', there's always some point at which analog is converted to digital, and of course it has to be converted back from digital to analog before you can listen to it with your human ears (analog ears)."
those would be my answers, but you should for sure use the search feature of this website to look at all the discussions that have already taken place about this subject. there are way more opinions already out there than you're probably gonna get with this post.
ps - the official jerkstore answer to this question would have been:
Please tell me the difference between analog and digital in the way that it sounds
it's easy. just take the SPDIF output of any nice cd player, and plug it into any input on your preamp. this will allow you to evaluate most effectively exactly what digital sounds like.
kids, do not try that at home unless you got your volume set really, really low.
