   For once I disagree with you Dick. Good spectral synthesis will sound a lot   
   better than simple harmonic distortion. Whether it sounds any better than   
   the original (B/W limited version) is definitely another matter and purely   
   *subjective* of course. But let's not forget how popular the Aphex Aural   
   Exciter once was, and it's a lot easier to do a far better job these days   
   with digital techniques. (and yes I know it uses phase shifting etc. as well   
   as spectral synthesis, but the point remains I think that what *some* people   
   consider an "improvement" can be achieved, if that's all he is after)
