I can try to provide some experience. What I get with the 45 deg. toe-in and about 10 feet back equidistant from each speaker(I measure the distance with a ruler). The speakers are 3 ft in front of the back wall and I sit in the apex of a bay window with drapes. The sound narrows as you pull forward until at about 6 ft the players are clearly defined and static, like a 2d representation very clearly defined but spread slightly wider than the speakers 8ft seperation. As you pull back to about 10 ft + the the sound meshes and players bleed into the space occupied by each other and fill a broader space; more like you hear at a classical music concert hall. Further back into the room at about 14 ft the soundstage widens and broadens but the different instruments can begin to change orientation; ie, they might shift their place as the notes change. Hope this is of some use.
