To anyone who wants to try them, mine are for sale. I like them and think they definitely have a place in the upper echelon... but they don't play nice with my amp and are not different enough from my K340's to warrant keeping them. Steve can provide more details on what they are, but the price is pretty hard to beat. [$250 + shipping]
I'll be posting them up for sale on here and head-fi soon, but if someone is interested let me know and save me the trouble.
