I'm wondering... If you were going for a 2-chanel setup with the LFR1100s. Would a configuration like this work?

Take a CD/DVD-A/SACD/etc player with a quality pair of stereo outs, and run them into the DSP box. Then take the four outputs of the DSP and run them into the the front and surround channels of the 5.1 input of a receiver. As long as the receiver has the same amps on all five channels (as most do these days), it sounds like you'd be set.
