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.

I don't think you know what you are talking about. There's probably a good reason it's going to take a few months. The cards do EAX 2 over the DDL connections now, so they probably have to figure out how to do EAX 5.0 over the digital connection, OR, creative told them they couldn't support it till that time. Most likely reason? Because Creative has an X-Fi 2 or something up it's sleeve and doesn't want as direct of competition so soon. Just think about it a bit before you post.

You guys are morons. All EAX x.x does is create more realistic audio in games. Once all that info is calculated (by the sound card), it simply has to be output. You can do that with 6 (or more) analog jacks in the back of the card, or you can encode those multiple channel LPCM signals into a Dolby Digital or DTS stream and send to a receiver that way.

The digital S/PDIF spec doesn't have enough bandwidth to send all channels digtally, so they have to be compressed via Dolby Digital or DTS encoders (like going from WAV to mp3).

Not all surround receivers have 5.1 (or greater) analog inputs (like mine). So the only way to enjoy the EAX 5 in something more than stereo is to have the sound encoded into Dolby Digital or DTS.

Since you sound like you don't know what you're talking about, Dolby Digital and DTS are nothing more than a way to compress multiple audio channels to save bandwidth (again, like going from WAV to mp3). It can have EAX 1/2/3/4/5/x produced audio, a movie soundtrack, or whatever.
