No, the biggest difference is that digital is a sampled-time system, which
means that it's subject to time aliasing (usually just called aliasing).
It's truly a challenge to  make something sound close to it's analog
counterpart while sampling at just above the hearing threshold (<24KHz
bandwidth in a 48KHz system).  I was just reading an AES paper on how a
decent peak limiter would need a 6MHz sample rate to keep aliasing noise to
inaudible levels....  these days I guess that's a practicality, what with
2GHz Pentiums....

Compared to this problem, even controlling quantization noise seems simple
(well, maybe not THAT simple...)

...and this is just getting a reasonably 'transparent' translation beteween
digital and analog worlds, so that you might be able to appreciate
subtleties like modelling analog component drift & mismatch, etc...
