What I'm trying to say, is that these people don't have the question correct, or even complete, so their answers will be totally off the mark and wrong headed.
teo_audio  He is not talking about digital vs. analog in general but about particular difference - the lack of noise in digital.  I'm not sure if it is a tape hiss or surface noise but, according to him, it suppose to improve reception of music.  It suggests that adding noise to live acoustic performance in very quiet place, would improve it.  
Hmmmm. All those so called artifacts and analog tape still sounds better than digital. Go figure. By the way that dude in the video is definitely not an audiophile.
