Yea I need a portable DAC/AMP because im going to use it with my iphone x + B&W PX headphones and wanted to use it for my computer system when im home since I dont have a DAC for it. After further reading, you are right that the Mojo amp cant be bypassed, but I see many people saying they use it for their desktop set-up and have no problems. Supposedly it has a line level mode you can set it to if you want to use it for this purpose.
