Personally I find little value in putting all the amp needs in one box, particularly more than 5/7 channel....and still makes a difference as to distance/level involved. I'd rather have a stack of capable 2ch amps than one of these 11ch amps that basically only address the needs of the front 3 channels, maybe including some reduced levels for surrounds (assuming your distances and sensitivity levels work out if you do have 11h of amp)
