I have paired both an ARC LS-15 and LS-25 with a CJ MF2200. It sounded fine. I recently bought a used Sonographe SA-400 on eBay that I am going to test w/ the LS-15.
"Why would you do that?"... I suspect that some of the previous posters are shocked at the prospect of audio miscegenation represented by pairing ARC and CJ products. Yes, they overlap the same space. Yes, their reputations are build on historically different sound signatures. But go ahead and try it. Either you will like it or not.
