I am driving my Heresys with a pair of 40 watt mono amps and it is more than enough power to play louder that you could endure for any length of time..... I don't really play it loud, but the dynamics and effortlessness to drive allow pretty much any amp .
The Klipsch are also full, dynamic, and fun to listen to.
