Profi Opinion

"Compact design. Force. Control. Overview. These are the attributes that come to mind with the SDA 300. The lively sound of the French makes a lot of fun and invites to extended listening sessions. Even hungry loudspeakers like a Dynaudio Heritage (4 Ohm 85dB efficiency) are driven to the highest performance by the SDA 300. It played its way into my HIFI heart in record time."

Important notes:

No phono input.


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.


The SDA300 Signature offers excellent control with Apple or Android apps or the included remote. The slim 5″ TFT color display gives you the right information about the device functions and shows cover art and song details. As an all-in-one concept, it goes one step further by acting as a player-complete music system and integrated amplifier with ATOLL’s famous MOS-FET amplification, plus it is extremely flexible and allows for the connection of additional analog and digital sources.
