dsavitsk, I have heard two different sounding esw9s. The first was my old pair, which was pre-ordered, and the second was a pair bought by vorlon1, who after hearing mine, wanted them. There was about a year difference from when we got them. His pair had almost abrasive highs, and more of a mid-bass emphasis than my pair, which seemed to have a lower-mid range emphasis in comparison. I didn't particularly like his, but he said his "settled down" after a few weeks. I never detected a change in mine, except what could be me just getting used to them after 20-30 hours. I've known Rob (vorlon1) for awhile and have had a few mini-meets with him, and trust his hearing. Hopefully, if you got a pair like his, they will also settle down. If not, maybe they're just not for you.
