Hmmm.
Being a bit nit-picky here, that depends on your starting point and your terms

of reference.
If you are making a real sound recording, at the point where the signal is

digitised the analog signal simply has to be 'superior'. I use quotes, because

having a bandwidth into hundreds of kHz, and unmeasurable distortion is not

necessarily useful.
The only possible exception I can think of is if you have a device that

directly turns sound pressure waves into a digital representation. However,

even there you are in theory throwing some of the information away.
What happens later down the processing chain is, of course, another matter.
An electronically generated sound is likely to be far cleaner and more

predictable if it remains entirely in the digital domain until final

conversion to actual sound waves. But in terms of music, is that precision a

desirable thing?
Well that's my 2d :)

Say you have a poem and I have a tune.

Exchange them and we can both have a poem, a tune, and a song.
