Your observation is very valid. But at Head-Fi it is a much better situation at the high end forums that are about speaker-based systems. Head-Fiers are way more into music I believe. Maybe part of it is that you can't as easily show off, while narrating and pointing in space about how great your system is like you can in every speaker based system.
Employed in high end for 3 decades, my observation has been that many of the lower priced system owners enjoy their systems than the megabucks guys do.
Ever drive a twisty road in Southern California and see how slowly most real expensive Porsche owners, Ferrari owners, Lambo owners drive their cars? Most would not know a good handling care if it slapped them in the face. Poseurs, moist of them. Prestige chasers. Trying to impress others, but more pathetic, trying to impress themselves that they have made it. Meanwhile, some guy on an original Mini or old Porsche 914 is sliding his car through corners, heel-tow braking and downshifting, and driving the car near the limit. Or they are at the track. They are the real drivers, the real driving enthusiasts.
Those poseur drivers putting along showing off are like a lot of audio guys on other forums. They talk the talk of living music, but never go hear the real thing. Talk the talk but don't walk the walk.
Now, that's fine, if equipment worship is more their goal than feeding the music addiction. What bugs me is the hypocrisy: spouting dogmatically about what is the best, when they don't even know the sound of music. Which is why some $100k+ speakers that don't sound very good can sell well.
