OK, happened once again...posted before I went to work this morning, came home a few minutes ago, 3 pages/75 posts since I last checked in. Whew. I may have to quit work, it gets in the way! Anyway, glad you like the Pioneers, DS, have the 2000s on burn in, have to check on them later. They are really comfortable, did like the initial sound on them. Don't know how they compare to the lower models, didn't have much chance to compare at Best Buy.
On the subject of bass in headphones...yeah, there probably is too much, it's what people like. There was an article written on "real bass" in Stereophile not too long ago, the upshot of which was that it hardly exists in electronics the way it sounds in the real world anymore. I like the AT 1K's, makes for an exciting sound, like the Monster Gratitudes and M-L Mykro 90's, which don't present bloated bass at all, and are both midrange and detail -centric. Lots of different ways to float the boat...
As for sound quality and cost, no rational audiophile (I grant, those words could be considered an oxymoron) will pretend the law of diminishing returns doesn't exist, or kick in past a certain price point (price
erformance ratio). The question after that becomes, how much extra green are you willing to lay out for ever decreasing improvements in sound? To some, the subtle increases in reality, soundstage, openness, etc are worth spending big bucks to attain, to others not so much, it's a personal formula as to where you feel the price
erformance works for you. After all, a sax still sounds like a sax through poor system playing an MP3; you get the nuance of texture, space, and other types of audio nirvana through higher end sound. That's enough BS for 1 long post.
Just sayin...
