HiFi at sonoro thought ahead
The MAESTRO Quantum is based on the proven MAESTRO Quantum platformQuantum has been fundamentally redesigned in collaboration with industry icon Rainer Finck. Through the targeted optimization of key components and a completely revised circuit design, overall performance has been significantly improved. This means that it fits perfectly into sonoro's new sound philosophy in terms of sound quality, offering the best bass-rich and spatial sound.
Music throughout the house
Thanks to our specially developed sonoro multiroom technology, you can enjoy your favorite music wherever you want. Up to 32* rooms can be played simultaneously, divided into zones or individually. Our wired Audio-over-IP solution, which can be operated via a local network, ensures optimal sound distribution discreetly in the background.

SOUND. DESIGNED
The MAESTRO Quantum has been equipped with special software and hardware modifications to deliver sound in its purest form yet. A clear highlight is the True Fidelity mode, which deactivates or bypasses all non-essential components to enable a completely interference-free signal path. Enjoy your favorite music the way it should be: clear, unadulterated, and just as the artist intended.
The high-quality body the Signature Line lettering on the front and the newly developed volume control with Diamond Grip give the MAESTRO Quantum an elegant design that combines classic elements with modern aesthetics. The speaker terminals have also been redesigned and are identical to those used on our ORCHESTRA Shaped Signature .
