Keep in mind that the Thiels are power hungry. The more power the better. With that said, they can sound amazing with the right amp and like crap with the wrong one...very detailed.
The outlaw should work nicely as a pre.
Also, by having a seperate right/left amp and speakers, you will kill your theater sound. You really need the same speakers for L/R/Center and the same amp. If stereo is your main concern, then don't worry.
