Frequency response : The Platinum's bandwidth remained at the 15 kHz mark, while the Aureon cards' bandwidth levels were significantly higher. While the difference is minute, there is never the less a disparity between the two frequencies.

Noise level : It's the same story as at 44.1 kHz, with the Platinum EX in the lead, and the Platinum last.

Distortion : Again the Platinum lagged behind the three others, all three of which generated the same benchmarks.

Intermodulation : The Platinum was clearly last but the other three were very close.

Crosstalk : the results at 44 kHz were repeated here but the gap widened because the Platinum EX improved whereas the Aureons trailed off.
