ASUS today announced Essence STX II and Essence STX II 7.1, two new Hi-Fi-grade sound cards designed to delight audiophiles with 124dB signal-to-noise-ratio (SNR) clarity and a 600ohm-headphone amplifier.

Essence STX II and STX II 7.1 build on the success and huge popularity of ASUS Essence STX – the world’s first consumer sound card to deliver 124db SNR audio clarity plus 600ohm headphone amp, and the long-term holder of the number-one position in Head-Fi’s Sound Cards charts, as voted by highly-satisfied users globally.

Keeping the audiophile spirit and philosophy alive, the new Essence STX II and STX II 7.1 cards both feature a remarkable 124dB SNR for line-out connections and 120dB SNR for headphone listening. Precision clock is controlled by a temperature-compensated crystal oscillator (TCXO) clock source, optimized power delivery is assured with low-dropout (LDO) regulators and WIMA® capacitors deliver balanced sound.

With an amplifier capable of delivering impeccable output for up to 600ohm headphones, an additional gain control for in-ear monitor (IEM) headphones, high-quality MUSES operational amplifiers (op-amps) and an included op-amp swap kit, ASUS once again demonstrates its ability to redefine the sound card market.  Essence STX II 7.1 even has the ability to output true 7.1-channel surround sound, via the included simple-to-fit daughterboard.

Commenting on the launch, Ives Chiu, ASUS Product Manager for the Audio Sector in the Multimedia Business Department, said: “Four years after the debut of Essence STX, ASUS remains committed to delivering ever better high-end sound cards to delight the most demanding audiophiles. Drawing on years of experience in developing Essence One, Essence STU and Essence III, Essence STX II delivers meticulous design, quintessential performance and profound musicality — elements that shape the spirit of the whole Essence Hi-Fi series.”
