Audio components (and the systems they are connect to) can commit errors of "commission" and "ommission". Which is to say they get things "wrong", injecting sounds (distortions, phase anomalies, etc) that trigger our ears & brain to believe that something just isn’t right. Errors of ommission relates to leaving out information, or attenuating it (micro dynamics, trailing vocals, detail, space between the notes, etc). Then there’s the whole balance and coherence thing, and placing things in space where they belong.
When all the stars line up and the "suspension of disbelief" kicks in -- where we reach the point when we "disbelieve" were listening to a mere facsimile of a live performance but rather we’re there WITH the musicians, we have assembled a "resolving system."
