500 bucks or less, new or used, open or closed. I've yet to sample or own something that truly satisfies and delivers. I'm not a bass head, but I do appreciate it. Tight, visceral, but no boom or bloom. Fast, layered, with impact, without being over powering, bleeding, or felt physically. Precise and natural sounding - not artificial. I don't know, maybe I'm asking too much at this price point. Anyways, if you feel inclined, please let me know your pick, and maybe provide a quick summary of why you like it. I know I'll get different responses, because some like big bass, and some don't.
