ASUS Prepares Xonar Essence STX, the World's First Audio Card to Achieve 124dB SNR

ASUSTek is reportedly prepping ASUS Xonar Essence STX, the next installment in the Xonar sound card lineup. The report does not include information on EAX support or gaming experience with Essence STX, but it's the music that will really matter with this card. According to ASUS, the Xonar Essence STX will boast a Signal to Noise Ratio (SNR) of 124dB with 0.0003% distortion, and will be the first card available with an onboard headphone amp. The amp will drive up to 600ohms headphones with less than 100dB distortion. Whats more, Xonar Essence STX will provide independent outputs for headphones and normal audio. The whole card will be using high-quality Nichicon capacitors. The frequency response for Xonar Essence STX is <10~90 kHz @ 3.5dB. That's not all, just like some high-end Auzentech sound cards, the Xonar STX will also allow changing the original op-amp ICs, without having any soldering skills. Under the plastic of the card, there are op-amp sockets that will allow a replacement operational amplifier to be installed very easy. The release date and pricing information for this pure audiophile card are still to be proclaimed.

ASUS Preparing New Gamer and Audiophile Sound-Cards

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.
