IMO your'e either looking at Klipsch or Zu. Your setup screams for high efficiency speakers. As often for most of us, getting what you want within a price point is the rub. Zu Soul Supremes probably fit your system but they rarely show up for sale. Definition IV will blow you away but are out of your price range.
Another thing of note, if you opt for high efficiency, reducing your line noise is pretty important.
