to tackle the idea that if you feed more power you'd get more bass and better dynamics i graphed two dongle dac of very different power outputs.
audio recording of pink noise in the s12 planar iem fed by these 2 dongles :
* apple dongle (EU version) 31mW on it's se 3.5mm plug
* moondrop dawn 4.4 230mW on it's balanced 4.4mm plug
the graph looks the same though i'd swear i could hear more bass on the dawn 4.4, so it must be placebo as the graph don't show extra energy in the bass
another audio myth that don't show on measurements
