STREAMER / DAC / INTEGRATED AMPLIFIER​

The SDA300 Signature is designed to reproduce the integrity and complexity of musical textures with great fluidity. It offers free access to online radio stations and lets you play live, in high definition, on the main streaming platforms. It is open to your entire network and has very complete connectivity. It converts the digital signal to reproduce your audio files with striking realism. As an all-in-one concept, it goes even further by functioning as a complete music player and integrated amplifier, using the amplifier section of the IN300.
