Benchmark DAC1 HDR.
See whether 4kHz is emphsised or de-emphasised compared to the adjacent frequencies. One picture is with 44.1kHz sample rate digital signal input, the other with 55kHz sample rate digital signal input.
The ripple can be said to be small in some sense, but big compared to the ripple of probably-non-up-sampling DAC in iPhone.
