MQA will give you 96
That’s what it does on my BDA-1
I’ve gotten 192 on Qobuz
A lot of stuff that says HR on Qobuz locks at 44
Regular files also lock at 44
The HI Res may be 24bit instead of 16, I have no way of telling
Qobuz will do 24/192
Deezer is 16bit FLAC. Have no idea about Amazon
I wish Amazon would mark the files. There is no indication of the sample rate
I’ve never seen anything above 44 on Deezer, but I’ve only had it a short while
Just my brief observation, only had the DAC a week or so
Up sampling does not change the sampling rate on the front of the DAC
The manual has the up sampling info
