My soundstage is quite wide, high, and deep. I am impressed with these Motion 20's. I was afraid they may have some trouble filling my largish living room, but they have done very well. They are about 7' apart, toed in and tilted slightly back about 30" off the back wall. The Halo has proven to be the best investment yet. It is providing nice tansients and tansparency.

The Parasound did the trick. The Pure Direct (2 channel) feature on the Marantz produces a very large, deep, and tall soundstage through the amp. Some tracks actually fill the entire back wall with sound. For a <$10k system, I've hit a homer.
