Can't compare the two, as I've never heard the Klipsch but do own the CCB-8s. What might be a Hsu selling point is that the CCB-8s have the ability to project a solid stereo image/phantom center over a really wide sweet spot. In my set-up I can sit right in front of one of the speakers or on either far side of a 7-foot sofa and still hear a stereo image/phantom center that doesn't collapse to the nearest speaker to you, as it would with more conventional speakers. The stereo image remains anchored between the L/R speakers. Audioholics' review of them explores in detail the theory (time-intensity trading) and practical set-up requirements (extreme toe-in) to get this. Since I have a 2.1 system this effect means 3 or 4 people can still enjoy excellent dialogue intelligibility and stereo imaging without a center. But if you plan to invest in a 5.1 or greater system, this might not matter so much and you might save money with Klipsch.
As for overall sound quality, the CCB-8s are transparent and neutral--you'll hear whatever quality's on the source. So they're capable of expansive soundstaging and pinpoint imaging. Great for both music and movies. I re-watched T2 the other week and the soundscape was cavernous with excellent imaging, expanding beyond the speaker boundaries--with just two speakers and a sub. Good luck shopping!
