Funny thing about imaging. It has to exist in the recording. Often,

only way to get real image specificity, image height and imaging
front-to-back layering) just isn't done that much, commercially
Yes, height information! - it is probably an illusion, but it is when the
image leaves the monofilament between the loudspeakers and happen above and
outside them and you hear the room behind you that you got stereo right and
then you sit and wonder what 5.1 is all about 
Of course the Carlson bins made it happen all the time ...

To be honest, all stereo is an illusion. but I'm continually amazed at what an impressive illusion is possible with just a couple of good, well placed microphones. Image height is captured, One can close their eyes and pick out, in space, each instrument in the ensemble even when many instruments are playing together. One can hear that the brasses are behind the woodwinds, and the triangle "floats" over the left side of the orchestra, just like it does in the concert hall. Sure it's an illusion, but it can be a damned good one!
