Streaming AM Hi-Res via Line In

[Cunningham0406]

I’m planning on getting either the Era 300 or Audio Pro C20 speaker but have a query on getting the best out of my set-up.

I’m currently subscribed to Apple Music and was planning on using the line in connection from the speaker to my MacBook Pro via a HELM DAC/aux cable.

Will this enable me to listen to Apple Music Hi-Res lossless or at least 24bit/48khz? Or have I missed something?

To the best of my knowledge, MacOS works the same as Windows and Linux, it simply runs at a fixed sample rate and bit depth as set in the Audio Midi. No automatic sample rate switching.
This applies both to the headphone out and a USB DAC.
