I am also a person who has hearing aid, 30 years o wearing them. It is extremely difficult for me to have a conversation with anyone, if I am not wearing mine.
I have frequently asked about hearing aids for music. They do no exist. Hearings, all of them, are designed for the frequencies used in vocal communication, or as it is commonly referred to as the speech banana. The top end is around 8khz. The bottom end, IIRC, is about 250hz I have tried extensively to find better. They simply are no made. So if you have hearing loss in the upper frequencies, you will get less distinction in sound quality based on you stere equipment.
I hope this helps as you consider your journey toward musical nervana,
edit: I did just look up "high frequency" hearing aids. Some claim to goes as high as 10khz. Just like speakers, the claims of 20-20k can be very misleading. 20khz might be 10-20db, The drop off would have a very steep slope after 6k. That is the upper end of its actual and practical ability.
