"Also, I think the power supply of the DAC has got to be the most critical because not only is the DAC handling the audio range, but it is oversamplying at, at least, 8x the audio cutoff frequency, so the noise riding on the power supply has additional freq range in which to affect the results."
The "8x the audio cutoff frequency" is where the analog post filter is needed..... The RF noise reflected to the power supply (and surrounding electronics) is from the switching of the bits (essentially square waves, whose spectra run to RF), which occur more frequently at higher rates. So the noise spectra isn't so much related to sample rate, but higher rates will increase the intensity of the RF noise.
