@CraigVMN :
I also have tinnitus. Most days it is tolerable, occasionally though, the ringing is so bad that I am unable to sit and listen to music.
More often than not this is due to something that I did, like too much caffeine, or took an aspirin.
Like you, I have not had my hearing tested because I am the type of person who would dwell on the results and the problem would become worse.
Over the years, I have found that I am really annoyed by a lot of midrange. ( Male voices, some piano notes, for example)
To the point that if too loud, it physically hurts.
I am always cognizant of the volume of my listening, because I know that I will pay with increased ear-ringing later.
I have had very good luck with speakers that do not have a mid-range driver.
I know some listeners enjoy a lot of up-front midrange, but not me.
On my Marantz 1060, I back the midrange down a couple of notches from flat.
Between solid-state and tubes, I find that tubes are kinder to my ears.
I know that some of the above goes entirely against the grain, but my adjustments have allowed me to enjoy my systems, my favorite being an Empire 598 w/Grado Black2, Marantz 1060 used as a preamp, Stromberg-Carlson tube ASR-433, through Altec Valencia's.
As you can see, nothing earth-shattering equipment- wise but to me, very enjoyable and warm.
As suggested earlier, maybe a possible solution for you would be an equalizer, and adjust it until the sound pleases YOUR ears and don't worry about the smile, frown, or whatever....
In fact, because of this thread, I may experiment with my Soundcraftsmen equalizer this winter on my solid-state system.
My purpose with this "epistle" is to show empathy for your tinnitus and to give you an example how I deal with it, and am still able to enjoy music and the hobby.
I appreciate your frustration and hope that you find a way to enjoy your music (and hopefully, the hobby).
