I am using Mojo for my desk top system
iMac/Audirvana plus/Mojo/Wyred 4 Sound Mint/Harbeth 3PESR SE.
It is truly great DAC. Sound stage depth improved a lot and sweet but very detail sound. I can feel layers of player very easily.
I do not use headphone that much but headphone amp is plus.
I am using in line mode all the time .
I am very happy with this DAC.
