Recommended solid state amp for user with tinnitus

I second the pass labs xa25. It drives my B&W 804 d3s with no problem. Smooth, with resolution and no listening fatigue. I also have tinnitus in my left ear. 

You may not want to take this direction since HT is involved, but I have found switching preamps made the bigger, positive difference in the sound of my system. I went from 12AU7 signal tubes to 6SN7s and the sound was much fuller, robust, detailed, natural and very non-fatiguing. I was very surprised at the difference it made. Much more enjoyable. I have a very, very slight ringing in my right ear sometimes, not all the time. It got pronounced if I listened too loud or long using my old preamp. I am 64.

Samster,
Lots of good suggestions here.  I'd start with your Classe option "B" simply because you'll use what you already have.  If the audio results are not acceptable, then you could undo the modification to your system and try one or more of the suggestions offered here.  If the audio results are acceptable but the modification doesn't give you the tinnitus relief you're hoping for, then you could try one or more of the suggestions.
I hope you'll keep us informed.

Try a pre Clarion McIntosh, I have the MC7270, very smooth top end. Classic McIntosh at less than half the price of new. If you don't get the results you want you can always get your money back out of it.

Hi Sam, I'm a musician and got tinnitus in my 30's which was a very loud constant ringing in both ears. I'd like to tell you about how I was able to reduce the ringing issue by 90%. It took a long time as in 5+ years but in my situation it was something I needed to try to do. It occurred to me that if the cause was damage to the cilia and the resulting random nerve activity it seemed intuitive that if the ear system got some "rest" it might help reduce not the damage per se but help quiet the whole system that causes the ringing. It worked. What I did was get ear plugs and wear them anytime I was awake and did not need to hear critically. So just around the house, traveling to and from work, etc. Now in my case the worst part was in playing music especially piano loud passages would ping my ears and cause louder ringing. Any loud sound louder than a mezzo forte would cause audible ringing to get worse for a short time. Over about 3 months of "resting" my ear with the plugs I noticed a obvious reduction in the reaction to louder sounds but still there was the constant ring. Over 12 months of faithfully using the plugs and avoiding like the plague really loud sounds for instance outside a jack hammer I notice a very significant reduction in the ping and also a  reduction in the ringing at night and in silent environments. I stopped going to concerts and stopped playing records for the first year also. This was itself "painful" but I felt necessary. I do not recall exactly but after 2-3 years of constant plugs (I got so used to it it was not a burden) the night ringing was reduced 50% and the ping was gone for loud piano playing. All in all I think I did the plugs for about 10 years slowly trailing off on how long during waking hours I wore them. After that period the ping went away except for very loud sudden sounds and the constant ring was reduced around 80+% Now I am able to play a sax or trumpet and go to a symphony concert and sit close up and not have those things re-excite the tinnitus. I still have a low level ring all the time but it's so low now that I can hear it only in 100% quiet at night and it's too quiet to bother me falling to sleep which was not true in the old days. I found by this experiment that absolute and long term rest of the hearing system allows something to occur which reduces the strength of the nerve firings by a huge percentage.  Good luck!
