Someone might not hear sibilance if the system is using components/cables that play with the treble or the system is less than transparent or the listener is not particularly bothered by it such that they do not notice it or maybe a million other things.
Just because someone does not hear it does not mean it is not there. For example, in the short demo set up for me by my dealer, I heard no sibilance (Esoteric P-03/D-03, BAT pre and amp and Transparent cables) but when I got them home it was unmistakable.
