Sehring 700 series (700 monitor, or 702 floorstander)
One caveat, I am a dealer but I feel strongly that I should post on this question. I believe that the new Sehring speakers, handcrafted and designed in Germany, would absolutely fit your desires.
They are the most liquid midrange of any speaker I have heard, the BEST tweeter (extended, wide and not sharp at all, very very lifelike), imaging is the best I have heard, depth of stage is the best, width is the best. All in all, hard to make these claims but they are my favorite speaker.
The 700 monitor is perfect, but is lacking a little in the deepest octaves. The 702 adds the deepest octaves and provides an almost spiritual experience when listening to orchestras.
