Mr E- I don't need an explanation. As I stated earlier: If you don't believe it, or can't hear it- enjoy your bliss! (Just for the sake of response though) There are quite a few things in audio that create audible effects(time smearing, loss of image specificity or ambience info, etc), that cannot be measured with the equipment now available. The human ear has been shown, time and again, to be very sensitive to aberrations, that are not quantifiable. BUT, like everything else in this hobby; whether your ears, brain or system, are up to the task of such discernment, determines your mileage.
