I just tried it and it won't work testing what the true bit rate is from Amazon music because of the system sample rate as you mentioned. If you play "HD" (ie, 16/44 CD quality) it will always show as the sample rate that you set in the MIDI (on a MAC). I tried 192kHz, 352kHz and 384kHz and the DAC always displayed whatever the system sample rate was.
another built-in flaw with amazon? any other music app that i have will automatically detect the sampling rates of my DAC and still *will only play at the max sample rate of the actual sample music*. it seems like what you're saying amazon requires you to pre-select some sample rate from your dac and will output that to that rate no matter what the original sample is?
