@cd318 Quite a difference between Harbeth’s and JBL L100’s!! Presumably your sister was primarily into rock, which might explain the preference for JBL’s.
Your presumption is correct.
If I remember correctly from what she told me, Howard demonstrated both the SLH5s and the C7ES3s which she thought were better but neither were to her taste.
Apparently Howard had been into rock himself and was familiar with what the JBLs could do.
It sometimes pays to have a dealer that has a wide range of tastes and experience in music.
Perhaps every good dealer or reviewer should have that?
