ARM+CPLD as the core audio framework
The M2 uses native decoding & asynchronous clock technology from independent R&D. The kernel program took over a year. Itâ€²s all about the sound quality.
Five TI chips to constitute the whole power supply system
The M2 uses high precision clock as the master device, and uses sampling pulse to force synchronizing the WAV data from ARM. ARM uses ping-pong buffer to process the data, and itâ€²s guaranteed the I2S data wonâ€²t be interfered by operation or the micro SD card reading. Everything is based on high precision clocks, which leads to the extremely high fidelity!
The M2 pro uses the only customized ultra-low jitter crystal oscillator 7050 from CRISTEK as the core component
The M2 uses CRISTEKâ€²s crystal oscillator of which the lowest phase noise can be -170dB. Itâ€²s extremely low.The M2 chooses the best clock crystal oscillator, only to pursue the best sound.
Superb hardware design from experience accumulation
The main board is rationally quartered - equally divided into the power supply part, the digital part, the DAC part and the Amp part. The whole circuit uses high level water flowing type wiring; the analog part is mirror-symmetric; every port is in the closest position.
Creative design of built-in Amp positive and negative power supply Class A
The Amp part occupies 1/4 of the PCB, which is quite a lot among all the portable players on the market. It uses the structure of the ultra-low distortion Op Amp and 10 discrete transistors. The output uses NPN+PNP geminate transistors. The quiescent current at last stage of each transistor is 15MA. Ultra linear Class A biasing.
