Auzen X-Fi Prelude 7.1 Sound Card Review
If you want the audio fidelity of the Creative Sound Blaster X-Fi Elite Pro but with a price tag below $200, then you absolutely must take a look at the Auzen X-Fi Prelude 7.1 sound card.
Designed and built by Auzentech around the Creative X-Fi audio processor, the Auzen X-Fi Prelude 7.1 is chock-full of quality opamps and even 64MB of onboard X-RAM. This is definitely a sound card made for audiophiles who want to game as well.
