Taiwan-based Asus has launched its first USB digital-to-analog converter
(DAC), the Xonar Essence One. The USB DAC with the world's first 8x symmetrical up sampling technology, also features a 120dB signal-to-noise ratio (SNR), audiophile-class headphone
AMP and eleven operational amplifier (op-amp) design for tonal customization.
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, calims the company release.
Xonar Essence One features a fully swappable op-amp design. 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.
