Auzentech have just set up an official product page for their upcoming Soundblaster X-Fi based Prelude 7.1 sound card, this being the first third party sound card to enter the market with Creative's X-Fi processor.
If you felt the X-Fi had a lot of potential but fell short in some areas, chances are you'll love what Auzentech have lined up for us with this feature-rich variant. It's due for release within the next month or so.
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.
