Well, it APPEARS very random I grant you - in the time domain. But of course, as we all know, music is very structured - and you can see and hear this in the frequency domain. My - our - point is that dither's success is not dependent on structure being readily apparent to the naked eye, in the time domain! You seem to be visualising an averaging effect in the time domain for a sine wave (presumably because its cyclical structure is readily apparent in that domain) but of course the average of all those values would be zero. So, you are already subconsciously accepting that "only by thinking about frequencies can this dither thing be explained". All you need is to take this insight and push it a bit further; I don't think there's a person on earth that can understand this dither thing without referring to the frequency domain - just as several posters here have done.
