I was surprised to see the LCD-2 so far along the x-axis. Pleasantly surprised. I'd say the flowchart matches my experience - as far as my experience goes. (I've heard a third of the headphones on there.) Evidently I need to upgrade to speakers now.
The only point at which my chart would diverge - as far as my experience goes - is that I would have the HD800 and LCD-2 roughly neck and neck. I know, I know. But I really, really like my LCD-2. I usually think of the difference between the two as being something like the difference between the first- and third-persons. The LCD-2 is the former.
