I think that everyone that's posted here is "on," whether they admit it or not. In my opinion, being so doesn't necessarily mean you're still buying stuff, actively upgrading as you surely did at some point in your audiophile career. Being on means you recognize that good sound matters to achieving an optimal connection to the music one cares most about, that you care, that you at least wonder if a change might make a difference. Whether or not you choose to act on that thought is immaterial.
If you want to know who's off, look at your friends who aren't audiophiles—most of the people you know, I'd assume. They, of course, never got on. They still have the "stereo" they got in college or graduate school and when it breaks, they'll replace it with a box (with no visible wires) that starts playing music when they speak to it in a firm tone of voice: "Play Carol King!"
Those of us reading this thread are definitely on, and on for life. And you're my kind of people.
