Ever since its inception, ASUS' Xonar range of sound cards have quickly become a well-respected brand, offering excellent audio quality coupled with a burgeoning feature set to please both audiophiles and gamers alike.

The Xonar HDAV 1.3 Deluxe not only features all of the usual functionality you'd expect from a Xonar part, but also includes an HDMI output capable of outputting every audio format out of the sun, coupled with an additional video processor to improve video output quality to boot. It's the most fully featured discrete sound card we've ever seen here at Elite Bastards, but can it live up to its obvious potential? We take a look in our exclusive review.
