Решил сделать несколько необычное описание, было интересно, что получится.











И в конце инфа в виде текста:

Descriptions:
Ihifi960 is based on ihifi812 from years of research and development .This equipment had joined the rare coaxial / optical fiber output (optical fiber connection can achieve electrical isolation to prevent digital noise transmitted through the ground, so that the signal is more pure), the product can not only carry, more cross-border acts as a pure digital turntable / desktop CD role, providing high-quality end-to-end digital audio, not less than the effect of a high-end CD. Flexible file management is better than desktop CD. While it commendable remains 12 hours of battery life, while 30% smaller.
Filtering use solid state capacitor and polymer capacitor combination,that make power purity reached a new height, making a foundation for the voice of details and reducing the background noise music.
pure sweet sound, dark background, has a simulation feel.
