Trusted Reviews published a review of the Creative Audigy 4 Pro sound card
The Audigy Pro 4 is almost certainly the last of the Audigy line and represents an incremental change from Creative's previous Audigy cards. The card is a refinement of the technology Creative has been developing over the past few years aimed at creating features that balance leading-edge game audio technology with music creation capabilities. The Audigy 4 is not a card to tempt existing Audigy owners, for that Creative has its X-Fi based cards close to release, but it is a strong package both in terms of hardware and software.Creative Audigy 4 Pro
