I hope this thread doesn't devolve in to another boring digital vs analog argument. What I took from the article, which I really liked, is that people like McNair are picking out the aspects of analog recording and playback that a lot of people really like, and applying that to the digital world. What some would call minor imperfections and distortions, is what he is bringing back to. We as humans all have imperfections, and I think the importance bringing that to music, and to any art form really, cannot be understated.
It's kind of like the difference between and pop singer who uses auto-tune to correct imperfections in pitch. While objectively they are now more in tune, it's exactly those little imperfections and personal touches of a great singer that make their singing, or their art memorable and unique. It's like the brushstrokes of a great painting. It makes it a real human expression, and allows us to connect.
