Hello! So I was wondering if I need a more neutral sounding experience with no distortion and clear highs(treble and all that stuff) should I go for fiio Q1 or Dragonfly black? Also no hissing or any distortion I'm vocals(I need perfect vocals) and clear cymbals(I don't want them to sound unclear and distorted. So which one between those two DACs? Also what is the maximum ohms which the Black can drive? My headset is the Audiotechnica ATH M70x.
