This is such an interesting topic. I'm sure I've experienced hyperacusis, and, I don't know if there's a word for it, but, in a sort of slight twist to this subject, a kind of moderately negative neuro-musical fatigue where one does not want to listen to music in a dedicated sort of head-fi way but if it's incidental, OK, for short periods only. Of course there are times when it's clearly best to stop altogether.
When I'm not in a total burnout period, the sound of the harp, yeah, that giant stringed instrument that we know and love, can be a soothing, non-jarring antidote to multi-instrumental tangles of certain types of stuff. Google Lara Somogyi (great youtube videos, electronics enhanced harp), Lavinia Meijer, Brandi Younger, Magdalena Hoffman.
Or really any single instrument like a piano or acoustic guitar, for me, lets me enjoy sessions when I'm otherwise in a kind of burned out state but not entirely sick of sound plying my eardrums.
