I found this article quite interesting. Admittedly it's from the recording side of the equation, but it details some of the things that contribute to that analogue warmth sound that seems to have become the holy grail for digital!!

Re: Analogue warmth
That's very interesting....
I knew that part of the gulf in perceived quality between digital and chemical photography resulted from the difference response curves if the recording media to visible light...
Happenstance meant silver halide film had a response curve (S-shaped) that almost perfectly mimicked that of the human eye, while ccd's have a linear response...
It had never occurred to me that the same would be true in recording audio!
