Exactly, everyone just says that HD650's scale well, and seem to ignore the K701. I find the K701 superior technically to the HD650 when properly powered. Its just unparalleled at <600/700 dollar range in terms of soundstage, clarity, detail, speed or transient response, dynamics, etc. It just sounds more expensive and more "hi-fi" than other headphones in the price range. But of course, its got a pretty unique sound signature, and I see why its such a love or hate headphone. I personally love it, its my favorite headphone at the moment. Since I got it, HD650's and DT880's don't get any head time. As I'm currently at collage, my HD650's, DT880's and Q701's are resting at home until summer. I only have the K701's and DT990pro's with me.
