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 :)
