The Grandinote Demone is a power amplifier designed to fully express the potential of Magnetosolid-VHP technology, an extreme evolution of the Magnetosolid® concept developed by Massimiliano Magri. This fully balanced monoblock amplifier is based on the Futura model but diverges significantly from it thanks to a completely reimagined output stage. The technological heart of the Demone is not merely a statement of intent, but the result of more than twenty years of research and experimentation, where engineering precision meets a deep passion for music and the art of sound reproduction.

At the core of the project lies a simple yet radical idea: to preserve the musicality, warmth, and naturalness typical of tube amplifiers, while eliminating their structural limitations through a solid-state architecture. Magnetosolid® technology is inspired by tube amplifier schematics, but without using any vacuum tubes. The active components are entirely solid-state, yet the signal flows through in-house developed output transformers, built with custom magnetic cores and proprietary wire geometry. This results in an extremely wide frequency response, exceptional dynamics, and an extremely high damping factor—well beyond the capabilities of traditional tube designs.

The Demone delivers 60 watts into both 4 and 8 Ohms, operating strictly in Class A, with constant power draw and thermal requirements that call for adequate ventilation. Each monoblock features a balanced XLR input and employs discrete, fully dual mono circuits with no feedback and direct coupling between stages—meaning no capacitors are used along the signal path. Each internal circuit has its own dedicated power supply, ensuring maximum signal purity and absolute control over musical dynamics.

Listening to the Demone is a revelatory experience: music emerges with body, three-dimensionality, and tonal coherence, while maintaining a naturalness reminiscent of the finest tube amplifiers—but with the speed, precision, and extension that only top-tier solid-state technology can provide. The low end is deep and tightly controlled, the highs are open and crystalline, and the midrange captivates with presence and engaging musicality. Every note seems to arise from a pitch-black silence, articulated with clarity yet never analytical or sterile.

In a world dominated by technical jargon and objectivism, the Grandinote Demone boldly reaffirms the value of listening as an emotional, sensory, and cultural act. It is not a product for everyone, but for those who recognize its vision and essence, it becomes a rare and invaluable musical companion—capable of turning every track into a journey, every note into a memory. Its uniqueness lies in the ability to fuse the rationality of science with the passion of art, evoking that sonic “Dolce Vita” that only the finest Italian creations can deliver.
