It's not just that we're used to the analog sound, there is a definite 
psycho-acoustic difference. IMO.

It is possible to simulate oscillator drift et al., sure, but it is difficult 
to get good clean sine tones in the upper ranges digitally.

I saw / heard some nice external boxes at the Sounds Expo, I don't remember 
the manufacturer offhand (I will look it up). They did a nice Prophet and 
Moog style synth, both digitally modelled, so I know it is possible. When I 
have a bit of spare cash I will probably get one of these - I have to say I 
also like the MS2000, which is in a similar price range.
