The world's first DAC with 8x symmetrical upsampling technology
September, 2011 - 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 digital-to-analog converter (DAC), 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 a 120dB signal-to-noise ratio (SNR), audiophile-class headphone AMP and eleven operational amplifier (op-amp) design for distinct tonal customization.
Hi-Fi audio achieved with the world's first 8x symmetrical upsampling technology
While common upsampling USB DACs indistinguishably transfer various audio sources to 192kHz, the Xonar Essence One upsamples 44.1/88.2/176.4kHz input to 352.8kHz and 48/96/192kHz input to 384kHz symmetrically (Note: 44.1*8=352.8kHz; 48*8=384kHz). As a result, data volume is also increased by upsampling the bit-rate to 32bit, corresponding to the original content and faithfully preserving the details of the user's music collection.
Extreme audio clarity with 120dB SNR and a dedicated power supply
The average SNR, of other USB DACs is about 110dB, but with an extremely high 120dB SNR, the Xonar Essence One provides audiophiles with clearer sounds, enabling minute sound details to be heard while significantly reducing noise levels. A dedicated power supply ensures that clean power is delivered so the sharpest sound is heard, with excellent immunity to noise from the AC line.
Eleven swappable OP-amps for customizable tonal characters
The Xonar Essence One features a fully swappable op-amp design, unprecedented for a high-end USB DAC. An op-amp is the key part in a DAC that amplifies the analog signal and affects tonal characteristics, such as darkness or brightness of sound or the overall sound image. The Xonar Essence One allows the user to swap every op-amp that is on board, for a truly customizable sound.
