Klipsch, high end?

I often hear statements regarding Klipsch speakers as being a very good speaker for use with low powered, mass market receivers. Does this make Klipsch a "cheap" or low quality speaker? In other words, How well would Klipsch (specifically the KLF-30,RF-3 or RP-5)Hold up in a high end system of multiple Bryston amps and a Proceed AVP? I was considering one of these Klipsch models and was wondering if they would be up to the task.
