I just replaced some $20 Vifa tweeters with some $60 Seas, small tweaks for voicing, and to her ears, went from painful to tolerable. For me, the voicing is slightly better. My ultimate test is Join Mitchel's voice. If Ladies of the Canyon sounds right, you have it.

One clue. The lower the distortion, the louder it can play without being objectionable. A Sax as loud as live is painful on most speakers. Only when the distortion comes down can I take that kind of level in my room.
I have a wife "test" of my own, when she would arrive home while I was listening to music, she would always turn it down or off (Grrr!) regardless of the music being played. When I upgraded to the low distortion Peerless hds exclusives, she started turning up the volume for the first time in 25 years.
There are a lot of different variables that could be accountable for her doing that, but low distortion seems to be the one factor that seemed to make the most sense. Until, of course, I read the Geddes study..The long term listening fatigue angle still maybe has hope though.

Distortion is distortion.

Diffraction is a type of distortion. Distortion is any variance from the original signal.

Over the years I have found that the effect of very low distortion speakers is to perceive them as not being "loud". The sensation of loudness *with* distortion is what most people refer to as "loud". The sensation of loudness without distortion is perceived as an increase in the *size* of the soundstage and/or the perception of being closer to the sound stage (either way the sound got "bigger").

Any way that you can beat down the sources of distortion, the better. The problem is that it is nearly impossible to get them all at the same time, thus we have various speaker designs that are more or less pleasing to any given listener depending on his/her thresholds and specific aspects of sensitivity to any given source of distortion.

My 2 cents.
