I'm an almost-exclusively-classical-music listener. Even if I knew any other audiophiles or audiophile clubs, their various musical tastes would undoubtedly send me reeling out of the room in disgust. I've learned long ago that whatever you might recommend to others, they aren't likely to hear or perceive anything the way you do. And though I live with somebody I dearly love, I wouldn't dream of subjecting her to my very exclusive taste in music...which is why I've put together the best possible headphone-only system I can barely afford. When she fires-up some crappy old pop tunes on YouTube, I just grin and bear it, and wait till she gets it out of her system. That's what love will do. She has an idea of the many thousands of dollars I've spent on my headphone rig...and yet has never had the slightest desire to have a listen.
So...I don't know if being an audiophile is a "disease" or not, but it seem to be a fairly solitary pursuit these days. Anyway, I'm happy with it and need no validation from others.
