OCD, autistic obsession and paranoia drive a lot of hobbies. Not just audiophila. I'm always amazed when I see people focusing on making sure that every one of their blu-rays is lined up on the shelf in alphabetical order, or worrying about not having one or two songs out of Frank Sinatra's output, or hauling around big ass WAV files on their phone because they can't sleep at night worrying that smaller file sizes might be throwing out something they might want. None of that stuff makes sense. I understand that people with these sorts of problems can't help themselves. I try to calm them down with facts and logic, but if that doesn't work, I just let them spin their wheels. If they keep their obsessions to themselves and don't try to visit them on other people, it's fine.
