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

I'm glad you made this post, and feel enlightened as to how many listeners are experiencing this.  I have had significant tinnitus and hearing loss in one ear for over twenty years (the other ear is going strong).  It was a radical paradigm shift: My initial response was increased anxiety and agitation at having a constant array of noises, swooshes, clicks, etc.  That goes away as you become accustomed to it.  Do what your doctor says, in order to minimize future changes in your hearing.   Unless they tell you to give up alcohol and caffeine.  In that case, nod your head and ignore them.

The biggest impact on my life has to do with human speech.  I avoid certain loud environments, because background noise interferes with my ability to decipher speech. 

A much rarer issue is bouts of vertigo which come every 5 years or so.  Those are debilitating, but only last for 24 hours.

As an audiophile, I would say the pros/cons are that I can't hear the noise floor of my system.  That saves a lot of money right there.  I can get by with $15,000 instead of $50,000.  I still perceive imaging, but it is noticeably weighted to one side; still there and beautiful, but different.  However, one ear functions perfectly, and I still have no tolerance for crappy equipment.  I really, really enjoy full range speakers, regardless of one side of my head being wonky.

rcprince:  Yes, my diagnosis is Meniere's.  But I think that diagnosis gets thrown at a collection of symptoms without an obvious cause.  (ie. not having a tumor or physical ear damage)  I have had a couple of different ENT's as I have moved around the country, and my experience is that they all tend to prescribe medication (steroids, anti-virals, etc.) when a "paradigm shift" of worsening symptoms is reported to them.  But I am unaware of any cases where anybody is able to reverse the situation.   Maybe your audiologist is aware, but also ask your ENT.
