If you know the characteristics you’re looking for and you hear a pair of speakers at a dealer that exhibits those characteristics better than others with your music (and any of your electronics you can bring to the audition), you’re probably in good shape unless your room is a disaster — but that’s on you and not the speakers. Short of auditioning at home that’s the best you can do and will minimize the chance for disappointment, but there are no guarantees — nature of the beast.
If you go through this rigorous process and find “the” speakers that sound best to you and reject them on measurements alone I feel sorry for you.
