I do think today's higher resolution equipment plays a large role in the epidemic of harshness. I don't recall hearing this kind of harshness in systems years ago. Higher resolution is quite often obtained by boosting upper mid and high frequencies, this acerbates harshness in recordings.
I've also found rather mundane parts quality in a lot of equipment. Upgrading capacitors and resistors can result in even higher resolution and much greater refinement.
I find too many recordings are excessively bright, again a problem with boosting upper mid and high frequencies.
All of this resolution does require careful system matching, getting the highest resolution and refinement is a delicate balancing act, easily the most difficult thing I've encountered in audio.
