Dithering does add noise to get a smoother sound at low volumes. I have read that the reason for dithering has something to do with psychoacoustics: Human ear does not like distortion like it is produced with quantisation noise, so "analogue" noise is added which makes the sound smoother while at the same time the noise is ignored or filtered by our mind. So in result, it sounds better even if we have added noise. I found this explanation at http://homerecording.de/modules/news/article.php?storyid=389, so if you can read german or use a translator, you maybe might understand what I wanted to say above :-) With kind regards Joerg
