ASUS Xonar D2 sound card review @ Elite Bastards
 

"This year has been a rather notable one for releases of high-profile discrete sound cards - A few weeks ago, we took a look at Auzentech's X-Fi Prelude, and today we sink our teeth into another part that has generated a lot of interest and publicity since being shown off at trade shows earlier this year, ASUS' Xonar D2. How well does it compete in this burgeoning market?"
