THIS THING: Apple Music have started to stream cd and HiRes quality files. It's important, as -for music lovers- now you get at least same quality as cd, and pay monthly not just for compressed files: it's like renting a huge collection of published real (bit by bit) albums. Very nice.
Apple say that HiRes, beyond 96kHz (Apple Music serves up to 192kHz files) can be read with a dedicated DAC. No more explicit instructions or how-to from Apple.
The internal DAC in Macs can be configured in "Sound MIDI SetUp Utility.app" (in Utilities folder), but it stays the same -chosen samplerate- whatever file is played (up to 96kHz).
I've chosen to set my
external DAC to 192, and internal (I use it sometimes) at 96kHz. Is it adequate to use "fixed" setting for every file? It doesn't automatically change when 44, 48, 96, 192kHz is playing.
Some third part music players can override OS setting and adjust automatically (my external DAC shows "sample-rate" in a screen, Audirvana works as expected).
AND: (I think this is irritating).
If you use Apple Music in a iOS device, all settings work perfectly well, automatically and without needed human intervention. I can connect my external DAC (Topping D10s) to lightning plug in iPad, and sample rate changes accordingly when listening to a list with varied qualities.
It just works.
Which one is the correct way of listening HiRes? The macOS way or iOS way? Perhaps it's indifferent...I don't know. And not a word is told in Apple's documentation in web, AFAIK, apart from selling the feature.
Why can't macs do this?:
(cd quality is ok for me, but I DO notice and appreciate a difference from old AAC files).
