About the SD9

The SMSL SD9 is a compact network music player and digital transport designed to feed an external DAC, amplifier, or active speaker system. It supports local playback from microSD cards and USB storage, network playback through Wi-Fi or Ethernet, DLNA, AirPlay, SAMBA/NAS, and two-way Bluetooth. Its digital outputs include optical, coaxial, AES/EBU, USB, and I2S over HDMI. The SD9 also functions as a USB DAC interface for a computer and as a USB digital transmitter to an external USB DAC. It supports MQA and high-resolution PCM and DSD playback, with HiBy Link control from a compatible mobile application. The supplied documentation and retailer listings identify the model as an older/currently hard-to-source product, but do not provide a definitive manufacturer statement that it has been officially discontinued.
