I have some experience with the Parasound JC-1's. What are your sonic priorities in a loudspeaker? Room/placement constraints? How loud do you listen? Need a wide sweet spot? And of course, ballpark budget?
The JC-1's are an excellent match with some speakers, and not very good with others (surprise, surprise). Don't pair them with a bright-sounding speaker, for example; pair them up with smooth-sounding speakers and the result will be both smooth and very dynamic. Best of both worlds.
Best of luck to you,
