Listen to live acoustic music as often as possible.
Sometimes when you do, listen critically… to the relation of detail to core instruments, how bass arrives, the sound stage, venue reflections. Micro details of cymbles, leading edge of the saxophone, tone of the violin, cello… decay of the piano… decay of the orchestra.
Is that what you hear in your system?
Season tickets to the symphony for ten years in 7th row center changed my goals and resultant system for the better more than all the high end audio system auditions I have been to.
