In its search for the purest essence of sound, ASUS have broken the boundaries with the newest soundcard on the market, the Xonar Essence ST. This PCI card is the world's first audio card to incorporate precision clock tuning to minimize audio jitter, bringing the user a clearer, crisper listening experience. The Xonar Essence ST card can also be upgraded to 7.1 channel output with the use of the Xonar H6 multi-channel extension board, which will be sold separately in the near future.

The Xonar Essence ST is capable of achieving an industry-leading 124dB SNR (Signal-to-Noise Ratio) in signal clarity and offers a built-in headphone amplifier to obtain the best performance out of any available pair of headphones. Thanks to ASUS' exclusive Hyper-grounding and EMI Shield design, even the most demanding audiophile will be satisfied with the unprecedented sound quality.
