I own a few RBH products and have to say they are top notch,... the JBL, Athena and Energy are not in the same league. The Canton's,.. maybe, but I have never heard them so I really couldn't say. I have some MC-4C's, an MC-414C, and a TS-10AP in my secondary HT system (very similar to the CT series) you may want to listen to a sytem like that if you prefer a more traditional bookshelf type speaker. Also IMO the TS-10AP is a much better sub than the CT's MS-8.1 or MS-10.1. Unfortunately an MC system is almost double the cost of the CT. In any case for value and performance I would highly recommend any RBH system over any of the others you mentioned.
