The story behind the new Essence series of Xonar

Aiming to create a classic master piece, the development of the new Xonar Essence line has
triggered us to engage a new quest in search for true high end audio and the essence of sound.
We looked for all traces and only to realize that the answer lies in the very root of our own
culture, and that it is the process of searching for the purest sound in harmony with man and the
environment that defines the highest level of audio.

4000 years ago, our ancestors were also searching for instruments that play the heavenly music,
not just to pay homage to the gods, but also to represent the harmony between man and nature.
Throughout the time, they crystallized their knowledge of the materials and the spiritual pursuit into
that piece of the Chime of Tiger.

Like our ancestors, the Xonar team also searched for only the best components and used only
the finest designs in order to reproduce that purest essence of sound. As the Chime of Tiger totem
gold-plated on our EMI shield, Xonar Essence STX was born with the mixture of ancient but never
changed spirit and nowadays cutting-edge technologies.

This Audio Precision test report was prepared not only to back up the unprecedented performance
of Xonar Essence STX, but is also a footnote of our ongoing quest in search for the essence of
sound.
