depends on your preferences in sound, available budget and space contraints.
by the cost of the receiver alone it seems like you're willing to shell out $5000 or so on a setup. before spending such cash i would hope you can at least answer the above topics otherwise anyone who wants to help is just flying blind giving just personal recommendations.
i'm a klipsch fan myself. i own a set of satellites in a more moderately priced $1500 setup. go preview some bookshelves and floorstanders at a local audio store, you might enjoy them as well.
i'm sure someone else will give a few more brand ideas.
