I also notice you have my other possible choice the bitfrost multibit any thoughts on the better dac with pairing with a jotunheim????
I find that Bifrost Multibit provides a wider soundstage, a little bit more depth and upper frequency detail than the Mojo. Mojo however sounds a tiny bit warmer, but is also very quick and resolving. Which of the two DACs being better at quick and resolving is debatable. Anyways, you won't have to worry about batteries degrading quickly due to always 100% charged when used as a desktop if you choose to get a desktop DAC equal or slightly better than Mojo (Bifrost Multibit for me). As for the comment with Lyr 2 being more resolving than Asgard 2, IMO I find the Asgard 2 and Jotunheim certainly better resolving in terms of making microdynamic transients sound clearer. If you want to explore more on the DACs, you can try the Questyle CMA600i balanced DAC, but I haven't heard it though so I can't compare it.
