Aesthetically Pleasing
ASUS is well known for its quality control, but beyond the hard and cold facts of
humidity storage and drop test, there’s the soft appeal and the intrinsic properties
that we look into when it comes to material selection. Whether it is sweat-proof and
nger print free surface nish, an elegant color palette or smooth curvatures, it is our
commitment to bring a state-of art audio with innovative material application and
usage.

Ultimate audio enjoyment with native Direct Stream Digital (DSD) support via DOP
Digital Stream Digital (DSD) is an encoding technology at 1 bit representation of the
audio waveform, allowing high reproduction of the original audio. With native DSD
support via DOP, the DSD container bypasses operating system through ASIO PCM,
hence allowing audiophiles to enjoy high-delity audio.
384kHz/24Bit 8X Symmetrical Upsampling Technology to restore lossless audio
The Essence One Series series can support up to 384kHz for multiples of 48kHz and
352.8kHz for multiples of 44.1kHz. This ensures that all sample rates are symmetrically
upsampled without any loss of resolution that provides pure representation of audio
content.
Built-in 600ohm headphone amplier drives all headphones on the market
Supports up to 600ohms impedance, allowing headphone enthusiasts to enjoy the
best of their favorite headphones without any additional amplication needed. The
headphone amplier powers up all Hi-Fi headphones with high performance and low
