Onkyo and Denon are kind of like Chevy and Ford. You will get varying opinions. It seems around here at least that Denon gets the edge in dependablitiy, while Onkyo seems to lead in features on the cutting edge. Either one will work fine with those speakers. Many here don't like the Klipsch sound. Audition a lot of speakers and buy the best you can afford. Speakers are what make your rig sound good, not receivers.
