So all i have learned here is that the iPhone X with a lighting adapter also sucks for the new black andros. It gives a colored sound heavy on the bass and lacking detail.
Chord Mojo with its <1 ohm OI also does this to a lesser extent but still way too thick for my tastes. That's why I use my iPod Touch 6G/7G with its 1.74 OI instead to give that punchy, well textured bass, incredible detail retrieval and out of the head soundstage. Only con with using iPod Touch 6G/7G is that since the mids and upper mids are much more pronounced than most DAPs whether in SE or Balanced (only with Andromeda IEM), sibilance is inevitable, but with a well mastered recording, it sounds extremely good to my ears.
