Have you tried addressing your tinnitus? I suffered tinnitus for years until I began taking vitamin D supplements and cut back on the drinking.
That said, it seems the inclination for those with tinnitus is to seek very smooth amps, like McIntosh, or those of class A topology. However, I found such amps were actually more fatiguing over long listening sessions. I moved onto a class AB Yamaha that is not exactly smooth but somehow is far less fatiguing. I have no explanation for why that is - maybe its circlotron circuit design that is very rare these days.
