@synsei I've got a mini-t in my kitchen powered from a squeezebox analogue out and connected to dali zensors wall mounted. No issues with fatigue there as it's the kit I listen to most in actual fact. I might try swapping them into my bedroom setup and see if that makes a difference. I will find the source of my treble problems, even if it kills me!
