A friend and very devoted audiophile lost hearing in one ear altogether and is poor in the other. He lives in Europe and has recieved care from specialists who have brought his hearing back to decent levels. During the time when it was real bad he used headphones with dedicated headphone amps. His was less frequency specific.
You might be surprised with modern headphone rigs they are better than good in many cases. I bought an OTL head amp from Singlepower with 6080 output tubes. It is incredible. My headpphones are AKG 701s which are marked down now due to a model change. You may want to try it.
My speaker recommendation echoes others I use Von Schweickerts and they don't cause fatigue if you get the VR2 which is the smallest floorstander. I think the English manufacturers are generally too warm one exception is KEF which may give you definition and warmth. I would think Dyne audio would be good if you can get a pair using their better tweeters. You won't get Esotars for that figure but Esotecs might squeeze in. For that same reason see if you can find the Morel speakers near you, they make great tweeters in the same style.
