Its all been said before, but to make matters worse, us audiophiles don't even have all the same taste in music. So when you take a niche and try to market to it, you have to divide that up another hundred or thousand times based on tastes and your not left with much left. I think this is why nothing has been done about it.
Take me for example. I am a lover of hi-fidelity but I am still well under 40, don't like jazz, beebop, chamber music or many of the other audiophile approved tunes. I am not alone, but there aren't too many like myself either.
Then we aren't the warmest and welcoming-est group either. We aren't out there trying to convert the masses, preaching the gospel of good sound. So by this we alienate ourselves more. anyway, its late and I am rambling....
