Fairlight-CMI

Hi

I always get fascinated how the quantisation (anti-aliasing) of lower 
bit-resolution samplers give the personality of its sound.  (I 
understand bitrate is not the only factor).  But if one can compare 
(II/IIx) and (III) based on its resolution.  Does it make a difference 
to its sound, let say, if we playing the same sample?

If there are differences beyond that fact, would that be due to the 
difference in its analog filter (if there is a difference)?

The reason I ask is because I am looking into acquiring a fairlight, 
and I'd like to find out the sound characteristics, beyond the kind of 
hardware/software specs.

Thanks in advance.
