from my perspective the imaging is natural...by that I mean that it varies with the type of recording...my wilsons are about 12' apart, 40" out from the rear wall and 5' or more from the side walls...I tend to be a fan of using the long wall as opposed to the tunnel...short wall approach...for me it tends to reduce, not eliminate, much of the characteristics of the typical room....in stereo mode the side to side image extends from the outside of the speakers...evening accross the front stage...depth tends do depend upon the type of music...Yo YO MA on solo cello versus a full orchesta...it does wonderfully on capturing the intimate flavor of a Jazz trio/quartet...etc....with the drums, bass and piano typically anchored....interesting to hear Miles Davis wander at times in some recordings...particular some of the live ones....thus I get a very nice sense of space...and spacinous around the player....
