Hi
For me reducing listening fatigue was quite an ordeal.
Here was the list of problems. I hope this can help with your battle with listening fatigue.
1) Lack of room treatment. My listening space had lots of bare walls.
2) Tweeter height on my speakers at the time. I put them on stands that put the tweeters right at my ear level. I did this because of aesthetics. I thought the speakers should be taller. The tweeters and speakers in general were supposed to be 6 inches below ear height.
3) The toe-in angle of my speakers was to sharp. I had them pointing at my ears. I had to decrease the toe-in by a bit.
4) Speaker cables weren't a match for my system. Even after over 400 hours of burn-in my ears would hurt on some recordings even after I handled some of the placement issues with the speakers.
5) Amp. It had a lot of gain and was too revealing. It was airy and gave me a lot of detail that I wanted but the cables and other issues the detail and harshness got too much.
It was a long journey but my listening fatigue is gone now but I had to make sweeping changes.
Good luck
