I haven't been able to see if the DAC that powers the headphone port supports 24-bit/192 kHz yet. Being able to listen to Lossless audio without a USB DAC would be nice.

It seems possible that Apple would add that since it's a feature of Apple Music Lossless.

During the video, they quickly mentioned that the jack supports high-impedance headphones and later specifically mention that you can connect “high-fidelity” headphones. Skip to about 33:30 in the video. So while nothing shows up on the spec page on their website, I wonder if they’re taking audio output more seriously.
