USB 2.0 Sound: Creative Labs Audigy 2 NX

Behavior At 48 KHz

Frequency response : Practically the same response as obtained at 44.1 kHz, which is rather disappointing.

Noise level : All things being equal, with the wider bandwidth, there is less noise. In any case, it is far from intrusive.

Dynamic capacity : The result is slightly better than at 44.1 kHz but the difference would certainly not be noticeable in practice.
