Aqua -
Judging by your description I'd recommend Aether Audio's(formerly S.P. Technology) Continuum 2.5, Continuum A.D., or the (somewhat large) stand mounted Timepiece 3.2 - the latter of which can actually be had as a new pair within your budget.
They're all wonderful speakers with a very natural, honest, dynamic, whole, and organic sound; detailed and informative, yet never intrusive or analytical.
