The M0 Lossless MP3 Player uses a special high density HDI PCB board from Microvia with multiple layers, so that a large number of components can be combined taking up less space.
Compared to the standard PCB board used in other MP3 players, this provides better electrical connectivity and also ensures that the signal interference is minimized to get the best quality sound. The M0 player is 38% smaller than the previous M1 music player from Shanling, yet has double the power.
For high quality sound the music player uses the ES9218P Sabre audio chip from ESS technologies. The tiny chip has a high quality 32 bit Quad DAC, integrated amplifier for the headphone, low output impedance and consumes very less power. The chip has a signal to noise ratio of 118dB and sampling rate of 384 kHz/32 bit
