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.

Appendix 1: Glossary • Noise Level The level of any undesired system noise signals over the audio spectrum, including AC mains hum, white noises, stray magnetic field, etc. • SNR Signal-to-Noise Ratio, the ratio of the maximum amplitude signal to the sum of the noise energy. The higher, the better. • THD+N Total Harmonic Distortion plus Noise, measured by attenuating the fundamental signal with a narrow band notch filter, then measuring the remaining signal which consists of harmonics of various order.
