I need some time to get back to you properly. Some notes,
Don't diss out the CJ because of its age. It is certainly much better than 60% of what you can get these days and it will cost you at least a grand to get something of comparable sound quality.
If you are into high end music experience, you should try to get voice matched front speakers, in essence right/left + center speakers designed to work together (similar frequency response, speed, neutrality and s/n rations). Sides or rears can be different since these are effect channels and will mostly reproduce "noises".
If you are not looking for the absolute ultimate in movie experience, get a package deal. They sound quite awesome and will not break the bank. Then keep the CJ + for 2 channel.
For 2 channel audio, its a different story... More to come
