Features With USB input and TOSLINK optical / coaxial /HDMI 12S output(can output at the same time), can work well with DAC, preamp, amplifier or speaker. Adopting XMOS XU208 chip solution, with 1000MIPS random access memory much higher than U8 (500MIPS), and more stable than Italian Amanero solution and coaxial output supports DSD DOP. Output interface with DSD ON function can match the decoder that needs DSD ON signal to decode DSD songs, supporting 44.1K-384KHz/16-32 Bit sampling rate and DOP DSD256 at highest, better signal process brings higher sound quality. High-quality components are used to ensure better performance, such as ultra-low noise LDO regulated power supply, LVDS differential chip, gold-plated coaxial interface, OS-CON solid capacitors and Panasonic FC filtering and decoupling capacitors, the contact internal resistance is smaller and the data transmission is more reliable. USB interface can be used as signal input and power input at the same time, and with external DC 5V input (with priority) that can be powered by phone charger or power bank, easy to enjoy HiFi music any time and any where.
