We really like the surround sound and higher quality of sound from the AV Amplifier. It is weird sometimes when watching a movie it sound like a person talking is coming in through the window or from down the hall as they approach the main scene.
And if my wife is not home, I can crank up the sound and watch a good "blowed em up real good" action movie at higher volumes than when she is here.
Going back to just the speaker from the TV is like so retro.
