I appreciate the kindness of everyone's sentiments, truly. I have consulted ENT and doing all, including resting my ears. I've done no system listening for 12 days (ouch)! - sounds are boxed in and unpleasant in general, and the car system is hard to ID words and some instruments - my brain fills in what is missing sorta. I would even pursue stem cell options if there is some promise. On the audio end, it's that I share regular listening sessions with audiophile friends, and I hope they remain pleasurable for all! Room DSP is a ver good thought, and one friend can help me with trying that out for my 10-12 hours of solo listening weekly. DSP would distort the sound for my friends who listen with me weekly, so I'd have to toggle it off and on. And how would this additional link affect a a pretty clean chain of reproduction? I know, cake and eat situation! I'll explore Roon as the Rossini in Roon-capable; I use it's Mosaic to store a library of titles, but without EQ capabilities. And fuzztone, I think your recommendation deserves my thorough consideration - it sounds like you are onto something fruitful. I will explore all the headphone-style recommendations generously shared here with me. Trouble is, I would merely glance at headphone equipment reviews in TAS, Stereophile, etc and so am woefully ignorant. Who here with hearing loss has addressed their loss through headphone listening, what was your approach to a musically satisfying solution - natural open sound, dynamics, image depth, timber, comfort of wearing headgear, etc. Any dealers who you know to specialize in this area? They deserve support and my consideration. I'm in NE Ohio and easily travel 4 or 5 hours for consultations. I follow this blog for years, don't comment much, but this is a great great of people with thoughtful recommendations on all audio arenas from which I have benefitted. Much respect!
