Look, as a victim of tinnitus I can say this with confidence: Whatever hearing limitations any one person has is a filter that persists continuously for that person at some level, day and night. Thus, everything I hear goes through that filter, including live music.
Thus, if I want my home system to be accurate, it has to sound like live music, so that the filter applied by my hearing afflictions applies to it the same way it applies to live sound. That preserves the illusion for me (and for anyone else listing to my system). This notion that my sound system needs to correct for a hearing deficiency assumes that I actually can know from experience what reality used to sound like and can make that comparison. I can't--hearing deficiencies don't turn on and off, they gradually develop over years and our brains apply corrections so that everything still sounds real to us. Trying to counteract those deficiencies results in an unreal sound.
Yes, tinnitus seems to come and go, but really I think it surges and diminishes. For me, the tinnitus becomes worse when what I'm listening to is very strong in high frequencies--the frequencies expressed by the ringing in my ears. So, the strategy of hot-rodding high-frequency response to overcome the hearing loss that has probably triggered tinnitus triggers it even worse.
In the end, I still want the system to be accurate--to take what's on the recording and project it as sound in my room with the same waveform characteristics as on the recording to the extent possible. And that we can measure.
