Poorer sound stage and bass impact, Focal Scala Utopia Evo vs  Focal Sopra N3???

I went to a Focal demo rooms to compare above two speakers but thought the Scala's performance is not as good as Sopra N3！To my surprise, that N3's stage is bigger, bass is deeper and more impactful vs Scala!
Among the two speakers,  Sopra N3 is a demo unit but Scala Utopia Evo is a new unit.
Both speakers are put in the same location between listening, using same Naim integrated amplifiers and cables.
 Any idea what may went wrong? I thought that it is may because of Scala needs more break in time or different position in the room
