Important Features

upsampling:
While common upsampling USB DACs just transfer whatever audio source to 192kHz
indistinguishably, 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 x
8 = 352.8kHz; 48 x 8 = 384kHz)
NOTES:
• Sample rate is the number of samples of audio carried per second, measured
in Hz or kHz (one kHz being 1,000 Hz). The more samples per second (the
higher the “sample rate”), the better the quality.
• Bit rate measures how much data is transmitted in a given amount of time. The
higher the bit rate, the higher the quality of the audio playback and the larger
the le.
• Upsampling is the process of increasing the sampling rate of a signal. For
instance, upsampling raster images such as photographs means increasing the
resolution of the image.
• Therefore, upsampling both sample rate and bit rate will make your audio
source sound clearer.
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 signicantly
reduces the noise level.
Audiophileclassheadphoneamplier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 amplier 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
amplies the analog signal in your soundcard and affects tone characters (darker, brighter,
sound image etc..) Xonar Essence One allows user to swap almost every OPamps for a fully
customized sound.
