Redefine your PC audio with the Asus Essence STX II Hi-Fi Sound Card.
The Essence STX II is a PCIe x1 solution engineered for audiophiles and audio purists who demand top-notch sound from their desktops. Built on the acclaimed Essence STX, it takes the legendary audio quality to a new level with an industry-leading 124 dB SNR, an ultra-low jitter clock source, a consistent power supply, and celebrated MUSES op-amps. The built-in premium headphone amplifier supports up to 600ohm-headphone impedance with additional gain for in-ear monitors (IEMs). For customizable listening, this card is armed with swappable sockets and three additional op-amps for quick, easy sound adjustment. The Essence STX II also supports Dolby Home Theater technologies for an elevated, evolved PC audio experience.

Industry-leading 124dB SNREssence STX II delivers industry-leading 124dB SNR audio clarity, a much-envied quality inherited from the revolutionary and widely-acclaimed Essence STX sound card — and up to 64 times better than typical onboard audio hardware. The headphone output reaches a fantastic 120dB SNR.
Premium-Quality Clock Source and Power SupplyA high-precision clock is crucial to audiophiles. Integrated circuits are susceptible to heat and temperature changes, which is why Essence STX II includes a premium temperature-compensated crystal oscillator (TCXO) clock source. It is an ultra-accurate timing technology that ensures ultra-low jitter. Essence STX II uses a dedicated four-pin Molex power connection rather than drawing power from the expansion slot like other cards, and that means a cleaner supply of electricity. An optimized power delivery is further ensured with high-fidelity low-dropout (LDO) regulators — unprecedented in the audio-card industry. In addition, audiophile-appreciated WIMA capacitors deliver balanced sound.
Celebrated MUSES op-ampsThe profound musicality that Essence listeners expect is encapsulated by celebrated MUSES 8920 and MUSES 8820 op-amps, which deliver true-to-life tonality and spacious sound imaging.
Impeccable headphone amplificationThe built-in headphone amplifier supports up to 600ohm impedance — so audiophiles can plug in the finest high-impedance headphones to enjoy the pure quality delivered by Essence STX II. Asus engineers have furnished Essence STX II with an additional gain control designed especially for high-sensitivity IEM headphones, allowing musicians and audio purists to use earpieces that channel audio output straight to the ear canal — isolating ambient noise for listening that requires undisturbed concentration.
Easily adjust the sound for your earsEssence STX II benefits from swappable op-amp sockets that allow users to create different timbres and tonal combinations. This card even comes with a swap kit that includes three additional op-amps — two Texas Instruments LME49720s and one MUSES 8820 — and a clamp tool that makes it easy to remove the op-amp microchips.
Advanced surround sound with instant encodingEssence STX II benefits from Dolby Home Theater technologies that turn your PC into a true home-theater system — boosting all your entertainment audio. Dolby Digital Live reproduces Dolby Digital 5.1-channel surround sound, immersing players in exciting and realistic entertainment experiences with high-quality surround that puts you at the center of the action. Dolby Virtual Speaker reshapes two-channel and 5.1-channel stereo content into virtual surround sound even with just two speakers, reproducing the dynamic, enveloping environment of a 5.1-speaker home theater system. Dolby Pro Logic II transforms high-quality stereo sound into rich and realistic 5.1-channel surround that completely changes your audio perception. Dolby Headphone simulates spectacular surround for personal audio by using powerful digital signal processing. It delivers up to 7.1-channel surround over any headphones for more vibrant and spacious listening.
