TweakTown posted a review on the Auzentech X-Fi Prelude 7.1 Sound Card
From a technical point of view we understand that Auzentech has fully licensed Creative Labs’ X-Fi chip onto their own proprietary circuit board design. So what does that mean? Well it means arguably the world’s fastest and most advanced audio processing at the average consumers reach right now, with upcoming driver support for Dolby Live, DTS interactive and since we have a Creative chip, the very latest in EAX surround technology.Auzentech X-Fi Prelude 7.1 Sound Card Review
My first impressions were good with a very noticeable notch up from the low-end after swapping from the Xonar. Not only did the low-end sound a lot beefier, it had a lot more character to it; more warmth and depth.
