The Xonar Essence One is a high-end USB DAC with the world's first 8x symmetrical upsampling, an extremely high 120 dB SNR, audiophile class headphone AMP with a full op-amps swappable function.

Hi-Fi audio through the world's first 8x symmetrical upsampling
The Essence One preserves faithful details of your music collection. While common upsampling USB DACs just transfer whatever audio source to 192 kHz indistinguishably, the Essence One upsamples 44.1/88.2/176.4 kHz input to 352.8 kHz and 48/96/192 kHz input to 384 kHz in a symmetrical manner. The Essence One also supports to increase data volume by upsampling the bit-rate to 32-bit corresponding to the original content.

Extreme audio clarity with 120 dB SNR
The average SNR of other USB DACs is about 110 dB. With the extremely high SNR (120 dB), the Xonar Essence One provides audiophiles clearer sounds with every detail while significantly reducing noise level.

Built-in headphone amp powers up even 600 ohms impedance headphones
The Xonar Essence One integrates an audiophile-class headphone AMP circuit which powers up all Hi-Fi headphones and grants 100% performance, even with impedance up to 600 ohms. It offers extra dynamics, sound details and low distortion.

11 swappable OP-amps for customizable tonal characters
This is the unprecedented attempt for any high-end USB DAC. Op-amp is the key part that amplifies the analog signal in your DAC and affects tone characters (darker, brighter, sound image, etc.). Xonar Essence One allows user to swap almost every OP-amps for a fully customized sound.

Clean sound thanks to a dedicated internal power supply
The internal power supply supports all international voltages and has generous margins for over and under voltage conditions. It provides the clean power for the clean sound with excellent immunity to noise on the AC line.

Balanced XLR output
The Xonar Essence One also features balanced (XLR) outputs. This is a higher quality output that is useful for eliminating unwanted noises and interference. Since a balanced line contains two signal carrying conductors of equal magnitude but opposite polarity, noises induced along the cable path cancel each other out when they reach the destination load.

Low clock jitter with asynchronous data transfer
Most USB audio uses synchronous data transfer mode to adjust the internal clock to compensate different data transfer rates between PCs and USB audio devices. But the jitter is worse if the transfer rate is different between a PC and the audio device. To avoid this issue, the ASUS Xonar Essence One supports asynchronous data transfer mode. This mechanism feedbacks the buffer status to the system, and the system is based on buffer status to adjust to the speed of the data transfer, which leads to a low amount of jitter in the Xonar Essence One.

Dedicated volume controls
The ASUS Xonar Essence One is fitted with two dedicated volume controls: one for the headphones and another for speakers. Unlike most USB DACs which use only one volume control for the output level of both headphone and speaker (or even no volume control), The Xonar Essence One allows users to set the headphone and speaker volume level separately.

Toslink and coaxial S/PDIF inputs
The ASUS Xonar Essence One is fitted with a set of digital inputs, coaxial and Toslink, which enable the connection of source components. The digital inputs accept data formats at sample rates up to 192 kHz.
