A Prima Donna on PC: Creative Labs Audigy 2

Audigy 2: Input/ Output Quality, Continued

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).

Results Right Mark Audio Analyser
Frequency response (from 40 Hz to 15 kHz), dB:+0.05, -0.17Very good
Noise level, dB (A):-92.5Very good
Dynamic range, dB (A):87.3Good
THD, %:0.0018Excellent
IMD, %:1.393Poor
Stereo crosstalk, dB:-85.1Excellent

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