Anyone with tinnitus or hearing loss who is into "high-end" audio?

Interesting about the vitamin D. I just started taking it for this COVID stuff. Maybe it will help my tinnitus.

Most Americans are Vitamin D "insufficient" I've been told. My doctor said I was "dangerously low" following my annual blood panel. It made sense because I was receiving little sun exposure due to spending most hours indoors studying for my masters. It had gotten so bad that I was having blurry vision spells and speech issues. Taking D supplements changed my life. Thinking back, I suspect I was probably deficient for years, but it wasn't until I switched PC physicians that they noticed. 

Even if it doesn't cure anyone's tinnitus, probably a good idea to take it anyway. Apparently it's needed for maintaining normal hormone levels.

My cousin has been a carpenter for 40 years, the skil-saws past 35 years is hard on his hearing.Me also, operating engineer for almost 30 years now, screaming Diesel engines for 25+ years is damaging.
 Even with earplugs, the 130DB DETROIT DIESEL, 3 feet from me for years, has taken its toll.
 I wear plugs at concerts,p for which I’m ridiculed, for, I don’t cares, trying to save what I have left.
my Father, local 150, as well, hearing loss young, high freq were gone. Cancer, and dead by age 74 (WAY TO DAMN YOUNG!!!!)

im in the same ship, chemicals, dust, haz-mat jobs, loud machines, etc etc.

 I can hear a difference , certain speakers, recordings, etc.

 take care of your hearing brothers/sisters., you only have a short time to protect your hearing.

 I still hit as many metal shows as I can, and OF COURSE EARPLUGS!!
 
THEY ACTUALLY MAKE THE MUSIC SOUND BETTER TO ME.

I have tinnitus but no loss of hearing compared to average people’s hearing, a test revealed that a have much greater sensitivity and range. It’s a bit of a curse, as every noise is more intense to me than to others around me. The shrieking and squealing of children and babies is particularly unpleasant to me. On the positive side, ambient background noises drown out the tinnitus, and very fortunately, music at moderate levels completely masks it. It’s only in the very quiet moments (such as when trying to fall asleep at night) that I most notice it. 

Well, same here but thankfully I also can still hear quite well to about 11kHz.
And I am quite aware if some mostly CD recordings are unpleasantly 'ear-flossing'. 
Though it's helpful to hear of the existence of more folks in audio persuits saddled with this rather unpleasant debility.
Not that I wish this on ANYONE, to be quite clear about it, please 😌

Yes, I have tinnitus and some hearing loss in left ear which has gotten worse because of tension neck problems. The more I sit on a couch, the worse it gets. 
Because of it my left ear is extremely sensitive to any problems in the rig. I have found out that ribbon tweeters and DACs with very clean highs are mandatory.
