Since completing my own, private home theater room, I have been listening to a lot of 2 channel stereo. I use my M22s and a HSU STF-2 subwoofer with my HK 525 set to "Surround Off". Even though the center channel is not in use, it definately "feels" like the vocals are coming out of the center. This is a good thing, right? My speakers are spaced out about 4 feet.
