Following the success of becoming the world's first sound cards to be equipped with the next generation DTS-HD Master Audio and Dolby Digital Plus bitstream on the PC platform, the ASUS Xonar HDAV1.3 Series once again moves to the forefront as the world's first and only solution to offer Dolby TrueHD audio bitstream on the PC platform. A powerful combination comprising of C-Media's custom-made AV200 audio processor and ArcSoft's TotalMedia Theatre software player lets users be the first to enjoy Dolby TrueHD's lossless compression rate of 24bit/192KHz over to their AV receivers. This breakthrough in the emerging Blu-ray era was unprecedented before the release of the Xonar HDAV1.3.

ASUS has sensed that there is a sizable market for discrete high-end sound cards, and is now out to grab its share. There are primarily two kinds of high-end sound card segments: gamer-grade and audiophile-grade. ASUS has created a new sound card to cater to each segment, though there could be more SKUs carved out of these sound card designs. The gamer-grade card, called Xonar Essence. From what the picture vaguely shows, the card continues to use the AV200 audio chipset, also seen is the bus translation logic, made by PLX. The card uses PCI-Express x1, though interestingly, requires that you collect a Molex connector to fuel it. It is said to carry industrial-grade Japanese capacitors. The portion of the card that houses vital DAC/ADC circuitry is covered by a fancy EMI shield. It is said that this card comes with a signal to noise ratio of 124 dB.

On with the audiophile card, ASUS has introduced the Xonar HDAV series sound cards. There are two cards: HDAV 1.3 and HDAV 1.3 Deluxe, depending on the presence of a daughter-card that expands the card's connectivity. The card uses RCA connectors for both digital and analog outputs. It also features two HDMI 1.3 ports for both output and input (for recording/mastering), is HDCP compliant and allows audio pass for protected Blu Ray content. The Xonar Essence awaits launch while Xonar HDAV 1.3 has been launched, and product page published. Pictures (in order) for Xonar Essence, Xonar HDAV 1.3 Deluxe, its connectors and package are provided.
