Hey El,
What I got out of this is a long winded video that simply states: "If you have good enough quality digital audio equipment, then what you put in is what you'll get out of it verbatim."

Exactly!

And bit depth it more important then sampling frequency.

+1 :thumb-up: , anything more than 48khz sample freq is mostly just going to make your file size huge (from a practical point of view), and anything less than 24bit bit depth (word based file formats eg .wav, .aif etc) will give you dynamic range limitations. But higher sample rates provide higher max freq (1/2 the sample rate is highest feq it can do (nyquist theorem)), but then all your audio gear has to able to cope and not chop the sound at 20khz (like most domestic amplifiers do) and also you speakers etc. And don't fall for the rave that "what's the point you can't hear that high" as all the sum and difference in the upper freq range colour the audible sounds (gives it air), e.g. Sony Super Audio goes flat to 100Khz (2 Ghz sampling serial not word based), so 2 100Khz combine to give 50khz, 2 50khz combine to give 25khz, 2 25kz combine to give 12.5khz (which you can hear)
