Advice on how to liquidate system

I agree with others on giving it at least a year, as a combination of healing and slight gear modifications (adding an equalizer) may allow you to regain your enjoyment of listening.  

I you end up deciding to sell all or some of your gear, I recommend TMR (The Music Room) in Erie Colorado.  I've sold gear to them twice... one time some large relatively expensive speakers.  They are very professional and make the process easy.

I would say wait awhile too.  I find many songs tell stories and I love those song even when the quality is not great.  Some are old or just not perfect clarity, but listening to the story is still fun.  I also listen to music on many different types of speakers and I still enjoy it - some are poor quality like in the garage or 10 headphones.  I guess what I am saying is that the level of enjoyment is not always matched to the quality of the sound.   

I empathize with your current situation. I had a temporary  loss of hearing in my right ear due to trauma 18 month later my hearing was at 70 to 80%.  Give it time friend. 

Sorry about your trauma.  I would sit on selling the system, as you might regain some hearing over the next year.  Also, are you a candidate fora cochlear implant?

Now 70 with very good hearing, however 30 years ago after working in munitions testing I have severe tinnitus, does it get better, does your hearing or, more likely, your brain, adapt?  I don't know but your hearing may well change, for the better with time. I sold excellent hifi gear and installed costly theatre system more for the family than me, now back with near audiophile gear.  Try headphones with good eq set up and patience. Good luck.
