You need to be a bit careful with the amp you choose if you go high power. Some amps get loud too fast and you can find it difficult to manage volume. I don't have direct experience with this but my understanding is Parasound specifically can have this challenge with high efficiency speakers. Although tonally they are fine with Klipsch, this evidently can be a problem. I had this conversation yesterday.
Cyrus is a good alternative for smaller SS. You could also look at other pure Class A amps. Sugden is brilliant and not crazy expensive.
