The first third-party X-Fi based sound card will have Dolby Digital Live and DTS:Interactive
Auzentech has posted detailed specifications of the upcoming
X-Fi Prelude 7.1
sound card. The
Auzentech X-Fi Prelude 7.1
is the first third party sound card based on the Creative Labs X-Fi sound processor.
Auzentech pairs the Creative Labs X-Fi CA20K audio processor with AKM digital-to-analog and analog-to-digital convertors. Auzentech employs four AKM AK4396VF DACs on
X-Fi Prelude 7.1
. The DACs boast 24-bit resolutions and 192 KHz sampling rates with a 120dB stereo signal-to-noise ratio. An AKM AK5394AVS ADC takes care of audio input duties. The ADC features 24-bit resolution and 192 KHz sampling rates.
The X-Fi Prelude 7.1 features a single user-replaceable front-channel OPAMP. Auzentech installs a National LM4562NA OPAMP with a rated 0.00003% total harmonic distortion levels on the X-Fi Prelude 7.1. The other six channels feature TI OPA2134 SoundPlus OPAMPs. The TI OPAMPs are not replaceable.
The new X-Fi Prelude 7.1 takes advantage of all X-Fi sound processor features including EAX Advanced HD 5.0, CMSS-3D, X-Fi Crystalizer and SoundFonts. Auzentech also installs 64MB of X-RAM on the X-Fi Prelude 7.1.
Eventually the Auzentech X-Fi Prelude 7.1 will feature multi-channel audio encoding technologies. Auzentech plans to add Dolby Digital Live support in Q4’2007 for Windows Vista and XP. DTS Interactive and DTS NEO:PC support is planned for Q1’2008 for Windows Vista and XP operating systems.

Actually PCIe latency has NO impact in games. The trouble that Creative mentioned earlier is related to ASIO used in professional audio application. It has something to do with the actual protocol. Some of those users need HW with minimal latency and will never buy a PCIe card if it has higher latency than an PCI card. And they buy the higher-priced cards.

True! Even PCI sometimes has an hard time keeping up with ASIO.
When is ASIO used? When listening to the soundcard captured input while it's recording. You like to hear how the sound is output while you're recording, and a delay is unacceptable in these cases. USB soundcards do have long delays which make them bad for real-time recording + output. That's why recording products either use a custom protocol, Ethernet or Firewire.
