I'll still be impatient for some movies, but yeah, the local theaters aren't going to be competing with my sound system.

My first impressions of the LFR1100s now that I'm running them correctly are that yes, the rear-firing drivers do add a bit to the depth of the sound. Just a little more natural. The ADA1000 certainly seems to be enough for them at this listening distance in this room. I'm playing them as loud as I can comfortably listen to them, and there's no hint of distortion. Loud and pure. So far I'm just listening to 2-channel music. It sounds like I'll be harder-pressed to notice a major difference with movies in full surround based on the limited comments already out there.
