For those speakers I would look towards a good quality newer Class D or Class D hybrid type amp.
Something along the line of the Rogue Pharoah or Peachtree's new Nova 300 (integrated amps) or Bel Canto ref600.
I have used older Bel Canto ref1000m amps with speakers having similar challenges for a number of years and remain satisified with those. A pair of these used would certainly do the job for nominal cost.
These amps will do a good technical job of bringing out the best in your speakers. If that still does not float your boat, then I would look to change speakers perhaps.
