The confusing thing is that the chip makers never clearly state how many bits a DAC is effectively working with, in terms of resolution. It could actually well be that even the lowly AKM4490 already puts out more than 24bits (noise-removed) resolution when fed with 32-bit data (only few, if any at all, DAC frontends supply 32bit data to the DAC chip proper, via I²S. Does anyone know a DAC that does?).
The heavily averaged synchronous measurements are good for test instrumentation but as you said not for real time audio.
