Fatigue might come from TIM distortions. In SS amplifiers with deep negative feedback output transistors go momentarily into saturation when feedback is too slow to respond to fast input signals (charge is trapped at semiconductor junction). These momentary gaps are not audible because our brains compensates by filling them. (causing fatigue).
Where does fatique come from?
I've heard systems in the past (also owned them ) that would fatique your ears after a certain amount of time. Always thought this was the speakers fault. Is this right? or a combination of Speakers, Receivers, Cd players, Etc. How much do you have to spend to get over the fatique factor, or is just personal to each person?
