In my experience a system that creates an experience of being real has 3 elements: truth, tonality (

), and dynamics.
Truth is, that everything on the recording is served up to you, nothing is glossed over, or has a layer of honey applied to it.
Tonality is, an absolute minimal extra distortion is contributed by the system on playback, the goal is for the reproduction components to be effectively inaudible.
Dynamics is, that this playback can made to occur at a volume level appropriate to, match the live musical event, if you were to experience it. This has to happen without truth and tonality falling off the table on the way ...
Get these 3 right, and you have all the "soul" in the world ...
