We all speak the same language...don't we?
Soundstage: The illusion of looking at an actual stage, some are wide or deep, some may me very small, but your system should duplicate the actual stage.
Imaging: A systems ability to let you see where singers, instruments, etc are within the soundstage. Up close, far back, a bit to the left and so forth.
Detail: To hear the resonance on a violin bow, not just hearing the violin, to hear the air moving through a saxaphone and real detail is hearing going through the sax . Also very define edges on where placement of instruments are on stage, these all show detail.
Presence: To feel that what you are listening to is in your room, or if you can close your eyes and imagine your presence there. Presence is Realism.
Someones examples should click with you.....If not, time for some new gear.
