Kdud66, I believe Lyngdorf recommendation to place speakers directly against the back wall is more than a nod to decorating. By placing the speakers as such, the direct sound and the most immediate reflected sound will be similar. Otherwise, the first sound that the ear recognizes if placed typically out from the back wall will have been unnecessarily and consequently unnaturaly corrected as though it was a reverberant sound. The depth provided by typically placing speakers out from the rear wall (and to allow for enough time between direct and reflected sound) could be argued to be a room induced reflection distorton and the ambience cues on the recording could be compromised. Furthermore placing the speakers against the back wall will have the bass frequencies achieve room induced lift that could relieve the amplification of some added work. That extra amplification energy might be better used for room correction.
I am surprised to see that Lyngdorf doesn’t recommend corner placement (though the odds of ideal spacing between speakers in otherwise optionless room corners would be unlikely), as that would further the concept.
Now I’m not negating your experience. How much recording engineers typically consider soundstage depth is another matter, and if adding artificial depth due to room induced distortion provides a more realistic experience for you, who am I to argue?
