STREAMER / DAC / INTEGRATED AMPLIFIER
The SDA300 Signature is designed to reproduce the integrity and complexity of music textures with great fluidity. It offers free access to Internet radios and lets you play live and in high definition from the leading streaming sites. It is open to your entire network and has very complete connectivity. It converts binary code into analog signal 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.

“This is why I will use the word miraculous one last time: this perfectly characterizes the price-performance ratio of our friend, the SDA300 Signature. And it’s all the more potent because it is made in France, with as many components of the exact origin as possible. Offering a high-end product at this very reasonable price is proof of intelligence in design and respectful elegance in our approach to the users/consumers.
Thank you, Gentlemen Dubreuil!”
