I originally built the system for home theater but I found that 7-stereo mode is fantastic for music. I listen to old time (pre-bluegrass), acid rock, classical (mostly strings), and jazz. I am astounded by the full sound in this configuration.
With all that said, I would not go with 200W/channel into heritige again. Sure, there's a lot of headroom, but it's really a waste of rack space and money. I've got a pair of k-horns in a stereo configuration and I can't even turn the volume knob to half way on a 35W/channel tube system without disturbing the neighbors.
Good luck making a choice. I don't think you'll be dissapointed if you do go with Outlaw.
