I think you need to specify their placement. On a bookshelf, ls3/5 (or derivatives thereof) are quite good, but away from the wall (where imaging can be appreciated, and when a reflex port can be tolerated) I'd lean to spica tc-50/60s, epos es-11 (or m-12), or another speaker I've never heard but which is getting a lot of good press, the green mountain audio europa. Many seem to like the new Quads as well.
Also it would help to know what your amp is since the above speakers vary wildly in sensitivity.
