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 the words of the mighty geico cavemen. Uhh.. what?

How exactly do you plan on getting your digital signal back into analog without DAC(s) (digital to analog conversion incase you didn't know)? If I want superior sound, I don't use a computer or a computer sound card whatsoever and I maybe don't even use digital unless it's for a movie for the surround sound.

As it stands, current Auzentech boards are horrible at gaming if you are using EAX, and yes, I use the Xplosion that connects to a AC-3 receiver. Stereo and positional audio is fine, but using EAX leads to pops, static, and other issues with a number of games.

makes sense Duraz0rz.. never thought about it that way

.. and thanks whoever for the bad rating ;) i LOVE IT!

lakku your right i should have read what i wrote.. i should have noted.. (as i did in an earlier post) that the dacs in creative cards (or any soundcard for that matter) are nowhere near as good as the dacs in almost any surround receiver.

and about eax and pops and static.. i have an xplosion and i have no problems.. all ive noticed is a big loss in framerate (7%-10%)

Might pick this up once DTS support is added. Good thing it is on the PCI bus, my only available 1x PCI-E slot is being used by my HDTV tuner (and that will NOT be removed for some sound card).

I wish sound cards still came with game ports though.....I still have controllers which work the same as the day I bought them (like my gravis joystick I bought back when I had my 486). I refuse to go out and buy new stuff when what I have works fine.

You guys sure have a lot to say. I'm a Hardware guy as far as computers go, but I know the least about sound cards and the way it works. My current setup is a 4.1 system with Logitch Z480(or was it 460) system. 400 Watts of power so it isn't weak. Sound is great compare to my original speakers my computer came WAY long time ago. Actually My this is my second Z480s as the original blew up one day at school when I touched my chair and the static electricity traveled across the floor and blew up my Sub-Woofer.

I have the Sound Blaster Audigy 2 sound card. I just built rebuild my computer and now have a core 2 duo E6600, Geforce 8800 GTS 320 graphic card, new case and so on.

Basically without all the introduction, I looked at the HT-Omega Claro/Claroplus+ cards, the AuzentechX-Meridian card, and the X-FI creative cards. I then decide to wait for the possibility of the X-Prelude which was suppose to come out at the end of may but delayed to what I thought was suppose to be June. So, is it even worth it to Upgrade with my current speaker system coming from Audigy 2, and if so Which one do you guys recommend.

In my opinion, if you're happy with the sound you are getting, then there is no reason to upgrade :)

Of course, if you want the best, then get the best. I'm getting it because I want the best sound quality I can get without sacrificing gaming performance and features.
