The external DAC and headphone amplifier is advertised as offering "audiophile-grade performance" and delivering USB connectivity and accessible external controls.

Asus has launched the Xonar Essence STU USB external digital-to-analog converter (DAC) and headphone amplifier, which the company touts as being based on the "acclaimed design and quality of Xonar Essence ST/STX internal sound cards and going beyond their already high standards."

The Xonar Essense STU features a Texas Instruments PCM1792A DAC and TPA6120A2 headphone amplifier that allows the user to switch between low and high settings to accommodate a wide range of headphones from in-ear headsets (16 to 32 ohms) to full-size headphones (up to 600 ohms). Also offered is a 120 dB signal-to-noise ratio due to its balanced (or mirrored) PCB layout that provides an "accurate reproduction of all sound sources and minimal component crosstalk, or interference."

The unit features dual volume controls, connectivity with USB compliant devices, stereo RCA out, a 6.3 mm headphone jack, two digital inputs, and auxiliary in. The Xonar Essence STU includes a bundled stand that permits vertical and horizontal orientation.

"We received considerable positive feedback from customers regarding the excellent sound quality of Xonar Essence ST/STX sound cards, which led us to develop Xonar Essence STU as a USB device that offers even more premium audio quality plus easy controls and connectivity to notebooks. This is another example of Asus listening to the community and acting on consumer demand," said Ives Chiu, Audiovisual Product Manager at the Asus Multimedia Business Unit.
