Maybe "wear out" isn't the best term. Crystals can drift (sometimes badly) and they can do that while just sitting dormant. It is also true that many of the older crystal filter designs paid scant attention to phase characteristics, basically just designing for best possible skirts. These filters were hard to listen to when they were new! In other words you may have filters in which some of the crystals have drifted or you may have filters that were always this way. Modern crystal filter design and DSP filters do pay attention to phase and depending upon type can be easier on the ears. We get used to the new stuff and maybe we don't like the old stuff as much as we remembered :-) Just a theory.
