I'm pretty much looking for something more immersive than anything. Seeing your post about getting the K701 to produce a fuller sound akin to maybe the DT990 or D7000 was very interesting to me. I've recently upgraded to a D7000 and have been seeing if there was something like it with that "open" sound. I have to say, coming from a HD555, the D7000 blew my mind. But of course like a true head-fi'er I'm already looking for the next best thing.
