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 wasn't sure what OPAMPS were, so I read the article on wikipedia. In a nutshell, these are the older (inferior?) version of the MOSFET which we are familiar with today. So my question for those of you in the know is: what would the advantage of using a 1960's designed OPAMP be as opposed to a modern MOSFET?
