Though Aune T1 isn`t tube amp but tube buffered DAC with SS amp, I find tube rolling having great effect and those cans do benefit from amping. Not much but just enough what`s needed to make them sound tighter and more accurate. After longer burn-in, for me personally, Fidelio X1 + Aune T1 + Siemens E88CC grey shield goldpin is The End Game as desktop rig.

Atm I have removed pads on my X1 because they are too high for my small ears and going to make custom angled pads shaped to my head which will take elements closer to ears (improvement in clarity and separation/imaging) and maybe even going to make wood grills
