It's either an USB cable or optical cable. Pick your poison. The DAC is not going to source itself. Maybe lucky if the Mojo2 has an embedded eMMC or microSD.
I don't use a phone, I use a battery-powered SBC. It's about 50mm all-around, so it's pocketable. I use a rotary encoder and an IR remote for the controls and a 50mm German OLED display. Nothing Chi-Fi in my system besides the battery, not even the OLED.
Like I said, we are all at different stages in this hobby. And have different preferences. I like pineapple on my pizza. Maybe at another stage, I won't like pineapple on my pizza. For now I like UK refined SQ. Off-the-shelf DACs are like those Fast and Furious cars that pull out besides me a few times a week, blasting loud distorted exaggerated SQ. They think they are all about SQ. Maybe at one stage I was like that too, blasting loud music as if it were SQ. But now I'm at the stage were I prefer refined UK SQ with zero background noise at a low volume.
The Mojo is a complement. I know I'm at the extreme and I don't expect anyone to forego the convenience of a DAP. But that's what DAPs are, convenience, not SQ.
Anyways, the Mojo2 is a distraction this year. I need to focus on my desktop rig. It's a tough grind as there is a lot of manual labor involved and a big rabbit hole. I'm at the extreme here too as I only use battery power. I don't use mains power. Like I said, no fatigue, no noise. Just pure unadulterated UK refined sound. If you prefer off-the-shelf Chi-Fi sound, more power to you. I'll check back here at Mojo2 release. Crossing fingers, but again I'm not ready for a Mojo2 but if it's an option...
