I evicted some Paradigm Reference speakers to make way for my LCR and BLS's, and while I ended up giving the sound quality nod to the Outlaws (see my review for the details) I still think very highly of the old Paradigms. The current Paradigm Ref line is probably going to cost you more than the Outlaws, but there's used hardware floating around that might appeal.

There is an abundance of good speaker brands, of course, and even among the really good ones there's a certain amount of variation based on personal taste. Even if you don't see a lot of suggestions here, you might check out the "Your System Saloon" for some other Gunslingers' systems to see what brands are popular.
