Noise and distortion are inevitable. Interestingly, though, noise can sometimes increase resolution...

How did you discover this relation?

I have made some tests, and found that people actually prefer some distortion.

By reading about sampling theory when I suddenly had to become an expert on digital oscilloscopes to pass a job interview.

Perhaps the addition of 'unwanted stuff' cancel some of the wanted stuff.

Whatever you prefer, the fact is information get lost throughout the whole recording and playback process.

Anything you care to elaborate?
This is quite interesting, as I have only come to the point of recognizing the effect.

For as long as there is no "reference" for the listener to consider as "absolutely neutral" or "correct",resolution and other aspects of a recording is purely a matter of perception/personal preference.

Dithering is the addition of noise to a digital system to increase resolution...

But how does that relate to an analog system?

The result is that the analog output of the digital system *sounds* better. Instead of correlated distortion products that sound objectionable, you get noise, often below the audibility threshold, and much less objectionable.

But I guess you know all that already
