It supply with Raspberry Pi power supply, no external power supply; and the use of ??-type filter power supply design, effectively reduce the interference of the power supply.
PCB board with gold plating on the tall, curved traces (high-end HIFI DAC is using curved alignment).
It is to better ensure the continuity of the impedance signal to reduce signal reflections and refractions.
When there is no network, it is easier to control playback.
I2S interface are using direct digital output, reproduction and high non-USB interface DAC mode.
