Auzentech X-Fi Prelude 7.1 (Source: Auzentech)
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.

In addition to the letancy issue mentioned above, people with video cards in SLI have no room to accommodate PCI-Express sound cards.

On the flip side, if we finally start seeing PCIe sound cards, I expect that we'll start seeing motherboards with nothing but PCIe slots.

The sound card is one of the last major components hanging on to the PCI bus (the only other thing that I can think of that doesn't have a PCIe version are wireless cards, but I doubt that those will be difficult to port to PCIe).

Once we start seeing PCIe only motherboards (or motherboards with just a single PCI slot) it won't be an issue to have SLI in your case.

PCIe soundcards can use the x4 or x1 lane, both of which can occupy along with the dual x16 lanes of SLI. Most manufs use this....

Not if you're using dual slot cards though.
