Before shelling out huge bucks for the likes of Grado's RS1i, I would look at the sr325i, as it seems to fit the description of the type of sound for which you're looking. They sound amazing on strings, their bass plumbs into the depths and they have a very expansive soundstage. Some people complain of sibilance/ too hot on the top end, but if you have quality, smooth sounding components, they may be a great match.
Btw, Johnny fyi - if i'm not mistaken, not all Beyer models are open. When I last looked, they had closed back models as well. Things could be different now, though... haven't checked out their products in a while.
