I confess I haven't heard any iterations of ADEL, but I do find it glaringly apparent that very few people on Head-fi seem willing to compromise even 1 inch on absolute sound quality, even if it means protecting their hearing an inch!
I mean, sure, audiophiles are uncompromising by nature, but what's the point in having the absolute last inch of SQ if, several years down the line, your ears become incapable of hearing the difference?
It amazes me how utterly irrelevant that seems to be to so many people here on Head-fi.
I don't have a horse in this particular race, and I don't view ADEL as a magic solution, but, as a rational person who cares about my hearing, I would much rather compromise just a little if it improved my chances of healthy longterm hearing.
Please note that this isn't a rant. It's simply remarking on the bizarreness of the apparent status quo on these forums.
