I’m not so sure about his HDCD tests there.
The fact that some labels have pushed MQA to Apple Music (like Qobuz and Amazon Music HD) makes it easy to test this with an MQA DAC. As you can’t get the infamous blue/magenta light without bit perfect playback (well a couple smart people have done some sneaky tricks but that’s for a different discussion) .
His test result here is proof of bit perfect playback, so something wrong with his HDCD tests:
I don’t have access to an MQA right now but will borrow from a friend for my own testing.
Hopefully someone else can test in the meantime and report back.
Try this if you have an MQA DAC.
