No Maril555, you need a pink noise reference track. Stereophile "Editor's Choice Sample & Test CD", available from Stereophile.com, has a pink noise track. When you play this, and when your speakers are properly placed, you will hear a strong centered pink noise image that gradually feathers out on the outside of the "ball". Close your eyes when you listen. This is important, in my experience. Listening with your eyes open ruins the illusion. When your speakers are properly placed laterally and from the rear wall, and when your listening position is the appropriate distance from the speakers, you will hear the illusion of a "ball" of sound, with width, height, and depth to this pink noise image.
If you don't already own it, Robert Harley's "Complete Guide to High End Audio" contains a good chapter on speaker placement, and the Von Schweikert owner's manual does a pretty good job, too.
