Output impedance on the headphone out (especially 1) is too high. Low impedance/high sensitivity IEMs (e.g Unique Melody Aero or Mage), sound terrible and have interaction issues (high noise floor, distorted frequency response). Even hp out 2 doesn't seem to fix it fully. (even a cowon d2 sounds better )

Not something I'd expect from a $600 amp/dac. Will be buying an nwaguy o2 amp for low impedance headphones and iems.

ps i suspect the quoted output impedance of 2ohm is actually higher
