If you are looking for Internet retailers similar to Outlaw in that you get to try the product out in home, Axiom Audio also takes the same approach. Also if I am not mistaken, AV123 takes the same approach.

For what it is worth and this is only an opinion, regardless of the brand you use, I found the best results were when the front 3 were matched for movies/tv. As I use my room as a gym and tv watching area, all of my speakers needed to match. I did n't like the tonal differences with different surrounds. I have a different set up than most people, so this resulted in trying a few different brands and configurations.
