What is meant when someone says a component is lacking soul


I have seen this mention in some reviews of the bell canto Evo 2i gen ii integrated amp.

A presentation lacking the hurdy-gurdies of dreams, the subjective bells and whistles of our symbolism factory...which are never really "there" in the first place.


can be applied to singers and musicians too...technically very good but no more...
"Soul" conveys the emotional impact, affecting your mood.  Like a good movie that plays on your emotions.
