1.Used the new ESS company’s D/A decoder chip ,ES9038PRO ,which was supplied with low noise voltage regulator ES9311.
2.The new XCORE-200 series chip XU-208 of XMOS is used to make the USB interface XU-208. The performance is doubled and the processing ability of 1000MIPS is achieved.
3.A specially developed clock system for XU-208 is designed to provide low noise and high precision clock signal to give full play to the performance of XU-208.
4.The ultra-low jitter DIR receiver chip is used as the input demodulation of S/PDIF signal, and the high quality IIS signal of ultra low JITTER is provided for the next stage of processing.
5.The new digital processing module provides every IIS signal with FIFO DE-JITTER processing, and provides the ultra-low noise clock signal. The whole digital system has high working frequency. A distributed secondary voltage regulator is designed to supply power to each IC, and the four-layer PCB layout of the whole machine is optimized.
6.The newly optimized fully balanced headset amplifier OB-1, a four-way fully consistent independent amplifier unit, has lower output impedance, higher driving capability and dynamic range.
