Harness Your Whole Library

The SMSL SD-9 HiFi Network Music Player lets you stream digital files from multiple sources. If your music library has gotten out of hand, the SD-9 helps you harness your entire storage ecosystem into a single integrated workflow. Connect hard disks, SD cards, DLNA devices, Bluetooth devices, Apple AirPlay devices, NASs, and more. 

Once everything’s integrated into the SD-9, you can send the output to a DAC, an amp, or even a pair of Bluetooth headphones. No more plugging and unplugging external drives. No more wrangling a million sources. Get a simple, intuitive, one-and-done solution. 

The ultimate music merger

Play your music no matter where or how it’s stored. Play from your phone via Bluetooth or Apple AirPlay. Connect a 4TB hard disk via USB. Play from a network-attached storage (NAS) via dual-band WiFi. You can even plug and play a Udisk or SD card. 

Dual-band WiFi support

The SD-9 keeps pace with your network, no matter the speed. Play music through Apple AirPlay, a DLNA device, a network-attached storage device and more with the fast, secure connection of dual-band WiFi. 

Play your way with six signal outputs

Once you’ve harnessed your library with the SD-9, you can output the signal in a number of ways. You can output it to a DAC via optical or coaxial or USB. You can output it to a balanced amp via AES/EBU. You can even send it to a pair of Bluetooth headphones. 

Intuitive interface

Navigate your library with the SD-9’s clear and intuitive menu. Simple operations and a bright 1.9” screen make browsing files and choosing music a breeze. 

1.9” display screen

Access album artwork, menus, and information on-the-fly with the 1.9” IPS LCD display screen. Get song information like artist, album, file type, bit-rate, and sampling frequency. Access menus with the full-function remote or wheel knob. See album artwork displayed in full color. 

DLNA and Apple Airplay all day

Don’t get rid of your stored lossless files; just bring them all online. Connect your entire audio storage ecosystem with DLNA and Apple Airplay via dual-band WiFi. 

Modern tempered glass top

The top of the SD-9 is covered with beautiful tempered glass for a sleek, modern aesthetic. 

Double frequency clocks eliminate jitter

Get precise audio playback of even the largest file types. The SD-9 decouples the decoding and clock management processes: a CPLD generates the audio clock with two audio frequency clocks, keeping the Audio SOC in lock-step to ensure precise, jitter-free playback.
