FLC8s would be the best choice I think :)

For me Xduoo X2 is the best little&very cheap dap.

One of the most comfortable IEMs are Mee Pinnacle P1. And they have good sound by the way :)

I think using Mojo with phone is very uncomfortable. You can think "it will be fine" but it won't be. It will get you mad :)   Take Onkyo/Pioneer or FiiO X7. But if the streaming wouldn't be necessary I would recomment other DAPs :)

I heard a lot about very good synergy of K7xx with Aune X1s and that's my type
