The SDA300 Signature is designed to reproduce the integrity and complexity of textures and the depth of music with great ease. Whether you use a dedicated NAS drive, a home computer music library, streaming via WiFi, Bluetooth, Internet radios, or even digital or analog inputs, all your files will be converted into high quality music. It converts binary code into an analog signal, preserving the integrity and joy of music.

All-In-One

The SDA300 Signature offers excellent control with Apple or Android apps or the included remote.
