true, i should have stated that explicitly.
but quantisation noise is just that, noise. every analog system has
noise, too, and yet people love it.
the important thing is to make the noise signal-independent, because
signal-dependent noise is very very nasty even at very low levels. this
is achieved by proper dithering. you can even push the noise where it is
to summarize, there are two physical constraints, and they are common to
analog and digital signals: bandwidth and dynamic range (or, more
precisely, signal-to-noise ratio). in both respects, digital systems
out-do analog ones easily, by orders of magnitude, if desired. so any
preference for analog has nothing to do with inherent superiority or
fidelity. either it's particular artefacts that are considered
"euphonic", or it's a sense of conceptual simplicity and elegance, or,
most often, the user's inability to understand digital systems combined
with incomplete understanding of analog systems.
