With most modern audio signals stored in digital format, the ASUS Xonar team has catered to audiophiles’ needs and launched its first hi-fi USB DAC (digital-to-analog converter), the Xonar Essence One. It is an industry-leading high-end USB DAC with the world’s first 8x symmetrical upsampling technology, while also featuring 120dB SNR, audiophile-class headphone AMP and eleven op-amps that are swappable for distinct tonal customization.

• Hi-Fi audio via the world-first 8x symmetrical upsampling
While common upsampling USB DACs just transfer whatever audio source to 192kHz indistingokuishably, Xonar Essence One upsamples 44.1/88.2 /176.4kHz input to 352.8kHz and 48/96/192kHz input to 384kHz in a symmetrical way, preserving the originality of your music collection, also upsample bit-rate to 32bit corresponding to the original contents. (Note: 44.1•8=352.8kHz; 48•8=384kHz)

• Extreme audio clarity with 120dB SNR
The SNR of normal USB DAC is about 110dB. With the extremely high SNR (>120dB), Xonar Essence One provides audiophiles clearer sounds with every details while significantly reduces the noise level.

• Audiophile class headphone amplifier output
The Xonar Essence One has built-in an audiophile-class headphone AMP circuit which grants 100% performance of ALL hi-end headphones, even with impedance up to 600ohms. The headphone amplifier powers up all Hi-Fi headphones with high performance and low distortion.

• User customizable tone characters by 11 swappable OP-amps
This is the unprecedented attempt for any hi-end USB DAC. Op-amp is the key part that amplifies the analog signal in your soundcard and affects tone characters(darker, brighter, sound image etc..).

• Balanced XLR output
Xonar Essence One also features balanced (XLR) outputs. This is a higher quality output that is useful for eliminating unwanted noises and interference.

• Dedicated Internal power supply
The internal power supply supports all international voltages and has generous margins for over and under voltage conditions. It provides cleanest power for cleanest sound with excellent immunity to noise on the AC line.
