I disagree with AudioTroy,
of all the modern SS amps out there the Hegel's are probably going to be actually good match. From what i hear from Hegel is slightly warmer sound perfect for the Klipsch heritage speakers. Sure tubes can be better but not always and maybe a class A amp (SS or Tube)would be better again. Depends on the amps but huge power is not needed and is a waist of money.
