It's certainly an interesting topic. At one point in the above link, the discussion turned to square waves and a compare of audeze,grado etc, pointing out possible pictorals of loose and tight graphs but what I find interesting is not that, since that is easily known from donning a set of grados, what is interesting is how there is never a mention, here or elsewhere about the possibility, even the remote chance, that there is such a thing as overtight bass. It's just assumed without question, the tighter the better. Natural bass is sometimes tight and sometimes loose, depending on one's gear, picking technique and the way it's recorded, but it's always within a range, it's never too sloppy or too tight. so maybe, maybe the best looking graph looks different than what they are looking for. Come on, it's a possibility that there are limits to tightness, punch, prat, and fidelity. More is not always better after a point............it reminds me about the increaing number of giant slalom skiers that have been dying in the last several years compared to when they didn't have the techno-adanced grease to put under their skis. their speed was limited in the past by lack of technology, and it was a good thing because the faster you get skiing down a hill the more tragic the result when you wipe out. And we have reached the point in skiing evolution where max safe normal natural speed has been reached and it's time to head back to normal town in the middle where all things find their natural resting place. look around in nature, everythings going up away from the middle in opposite directions and then falling back down. Things are not going faster and faster in a linear way. The seasons all have cycles, midpoints and perfect times as they have extremes. Some extrem-ists like the ends and live in the 120 degree desert heat, but most like the middle. Ask any statistician who is familiar with bell curves where most things are. Should bass be any different I ask myself?
