At a Glance: Here's what the MAESTRO Quantum Signature
"With the ' Signature ' line, we've given ourselves a gift. Hi-Fi at sonoro has never sounded this good. I'm incredibly proud of the entire team and the journey we've mastered together."
Marcell Faller CEO & Founder
HiFi at sonoro thought ahead
The MAESTRO Quantum Signature is based on the proven platform of the MAESTRO Quantum and has been fundamentally enhanced in collaboration with industry icon Rainer Finck. Through the targeted optimization of key components and a completely redesigned circuit layout, overall performance has been significantly improved. As a result, it fits seamlessly into sonoro’s new sound philosophy with its optimized sound and delivers the best bass-rich, spacious sound.
Music throughout the house
Thanks to our proprietary sonoro multiroom technology, you can enjoy your favorite music wherever you want. You can play music in up to 32* rooms simultaneously—either grouped into zones or individually. Our wired Audio-over-IP solution, which operates over a local network, ensures optimal sound distribution while running discreetly in the background. All new-generation sonoro music systems can be combined exactly as you wish. Optionally, you can use Apple AirPlay, Google Cast, or the new Bluetooth feature Auracast**.
*Operation of up to 32 sonoro multiroom-enabled music systems depends on the specific network infrastructure.
**Auracast ready. The full range of features will be made available at a later date via a software update.
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: 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’s 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 our ORCHESTRA Shaped Signature floorstanding speakers.
HiFi 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.
TV sound in hi-fi quality
Thanks to the HDMI port with CEC functionality, you c MAESTRO Quantum Signature easily and conveniently with your TV. Turning the device on and off, adjusting the volume—all of this can be controlled conveniently and effortlessly using your TV remote (provided your TV has an HDMI ARC or eARC output). Alternatively, you can use the optical or coaxial input.
