Hi-Fi at sonoro Thought Ahead
The MAESTRO Quantum Signature is based on the proven MAESTRO Quantum platform, which has been fundamentally redesigned in collaboration with industry icon Rainer Finck. Through the targeted optimisation 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.

Sound. Designed.
The MAESTRO Quantum Signature has been equipped with special software and hardware modifications to deliver sound in its purest form yet. A clear highlight is True Fidelity mode, which deactivates or bypasses all non-essential components to enable a completely interference-free signal path. Favourite music is heard the way it is meant to be heard: clear, unadulterated and exactly as the artist recorded it.

The high-quality “body” with the “Signature Line” lettering on the front and the newly developed volume control with Diamond Grip give the MAESTRO Quantum Signature an elegant design that combines classic elements with modern aesthetics. The speaker terminals have also been redesigned and are identical in construction to those installed on sonoro's ORCHESTRA Shaped Signature floorstanding speakers.

Music Throughout the House
Thanks to sonoro's proprietary multiroom technology, favourite music can be enjoyed wherever desired. Music can be played in up to 32 rooms simultaneously, either grouped into zones or individually. sonoro's wired Audio-over-IP solution, which operates over a local network, discreetly ensures optimal sound distribution in the background. All new-generation sonoro music systems can be combined exactly as required. Optionally, Apple AirPlay, Google Cast or the new Bluetooth feature Auracast can be used.

TV Sound in Hi-Fi Quality
Thanks to the HDMI connection with CEC function, the MAESTRO Quantum can be used conveniently and easily in conjunction with a TV. Switching on and off, turning the volume up and down: everything can be controlled using the TV remote control (HDMI ARC or eARC output on the TV required). Alternatively, the optical or coaxial input can be used.

Hi-Fi of the Next Level
In collaboration with industry icons Rainer Finck and Karl-Heinz Fink, sonoro has designed the Signature Line. In addition to the MAESTRO Quantum Signature, this line includes the ORCHESTRA Shaped Signature floorstanding speakers and the PLATINUM Signature turntable. With the Signature Line, sonoro is taking the next step. The goal: to establish a presence in the high-end market with products that offer high sound quality and a unique design, while remaining affordable for a broader audience.
