Pretty much all of that stuff in the pdf is crap....that's not backed up what so ever. For starters, I can hear down to 16hz and max out at 20khz in a hearing test, I don't attest to have golden ears, but I know that most people don't hear that low (genetics perhaps?).
Also, Nick, it's just a term used to compare the listening experiences of CD and vinyl - it's an inherently subjective term, so it's pretty hard to translate it into electrical terms, since "organic" is different to everyone. I would say most of it is probably due to euphonic distortion and noise (noise can be euphonic to many, just like visual noise can be visually appealing to a lot of people. From a poll back on an AV forum, ffdshow's most-used function was the "Noise" one).
