I was only two channel till I purchased my 568.1 back in early 2000.

Now I agree with Chris! The center channel especially anchors the center image in the middle even when your sitting off to one side. Plus Meridians surround music modes are so natural sounding. I only used my fronts and sub with the 568.1 but now with my 568.2 the surrounds are worth leaving on. All channels are upsampled now.
