The 16 bit/ 44.1 kHz tests gave positive results, though not the same level of quality. This is because when the Audigy 2 resamples all the 44.1 kHz flow rates in 48 kHz, corresponding to the DSP's internal frequency, rates above 48 kHz do not get resampled. So here we have a paradox: the Audigy 2 produces near-perfect sound in 24 bit/ 96 kHz playback (i.e. DVD Audio), but is not as good in 16 bit/ 44.1 kHz playback (such as CD Audio).

You can see the test results are generally positive, except for the intermodulation one. This is evidently due to resampling in 48 kHz.
