Mile High Roon. Exported my home library as 320k AAC, and setup my laptop as a core. Schiit Fulla2 driving Parrot Zik 3’s (over 3.5mm, their bluetooth is rubbish). iPad connected to an ad-hoc network worked perfectly, and gave me a few excellent hours of listening to and reading about my library over the pacific. Flight crew equal parts confused and impressed.
