Three decades of evolution, shaped around listening.

The U-280 SC 30th Anniversary is the principal tube power amplifier in the Margules universe and one of the clearest expressions of how we understand amplification.

For more than three decades, the U-280 has evolved around a single idea: preserving the harmonic structure, spatial dimension, and emotional character of music. Each generation has refined the relationship between circuit, tube, loudspeaker, and listener, bringing the ANA® philosophy to its most complete expression in amplification.

At the heart of that evolution is the Active Servo Bias system, which continuously adapts the operating conditions of the output stage to maintain pure Class A operation while allowing the use of different tube families without manual bias adjustment. Together with BEFS, zero global negative feedback, shunt-regulated power supplies, and Triode / Ultralinear operation, these technologies form a single architecture designed around perception rather than specification alone.

The U-280 can move from the intimacy and texture of Triode operation to the greater scale and authority of Ultralinear, and from stereo to monoblock configuration as the system evolves.

Thirty years of refinement have not changed its purpose.

To let amplification disappear, and music remain.

Built to be the center of your music system.

The ACRH-4 is a hybrid integrated amplifier designed for music lovers who value thoughtful engineering and the elegance of a complete solution. Combining a vacuum tube preamplifier, a fully discrete phono stage, and a high-current solid-state power amplifier, it brings together everything needed to build a refined two-channel music system in a single handcrafted component.

Designed under the ANA® philosophy, the ACRH-4 preserves harmonic coherence, natural tonal balance, and effortless musical flow while providing the control and authority to drive a wide variety of loudspeakers. Whether paired with bookshelf speakers for an intimate listening room or tower speakers for greater scale and dynamics, it adapts naturally to the way you listen.

As the centerpiece of the MAGENTA ecosystem, the ACRH-4 integrates seamlessly with every stage of your listening journey. It is the foundation of systems such as the Blue Set and the Magenta Set, while remaining equally at home with future upgrades. From compact bookshelf speakers to full-range tower speakers, from vinyl to digital sources, the ACRH-4 is designed to grow with your system—without ever replacing its heart.

Behind every MARGULES product is a process of engineering, listening, and continuous refinement.

Meet Brian González, part of our Engineering & Development team, where new amplifier designs, headphone prototypes, restoration, and service come together under one philosophy: creating systems that are built to perform for decades.

At MARGULES, our work goes beyond designing individual components. We develop complete listening solutions, integrating electronics, loudspeakers, acoustic design, and personalized system tuning to ensure every installation delivers the experience it was intended to.

Because great sound is not only designed. It is engineered, supported, and cared for throughout its lifetime.

Introducing PHORIA.

The first dedicated headphone listening system by Margules.

PHORIA brings Margules into the world of personal listening, combining handcrafted tube amplification with an integrated high-resolution music server in a single, purpose-built system.

Designed under the ANA® philosophy, its pure Class A OTL architecture, dedicated EL34 output tubes, and fully discrete analog circuitry preserve harmonic integrity, spatial realism, and effortless musical flow. Integrated streaming and high-resolution playback create a direct signal path that allows the music—not the technology—to take center stage.

Compatible with a wide range of high-performance headphones, PHORIA was conceived alongside the Margules Prelude headphones, where the ANA® philosophy reaches its most complete expression.

This is not simply a headphone amplifier.

It is a new way of experiencing the Margules sound.

Bespoke listening.

The FC-01 bespoke custom speakers was created for seeking a system that reflects both the character of the space and the way music is experienced within it.

Built upon the same acoustic architecture as the Magenta Monitor-3, the FC-01 Custom preserves the natural balance, phase coherence, and effortless musicality that define the Margules listening experience, while introducing a unique visual identity crafted specifically for its owner.

Designed to disappear into the listening experience, the FC-01 Custom reveals music with remarkable depth, natural tonal balance, and an immersive sense of space. Its carefully engineered cabinet minimizes unwanted resonances and diffraction, allowing instruments and voices to emerge with clarity, texture, and lifelike presence.

A first-order crossover preserves phase integrity and timing, while proprietary Margules engineering optimizes amplitude and impedance throughout the system. Together with long-excursion carbon fiber paper drivers and a soft-dome tweeter, every element works in harmony to reproduce music with coherence rather than exaggeration.

More than a custom finish, the FC-01 Custom is a personal interpretation of a proven acoustic design, one that allows the system to become part of its environment while leaving the music at the center of the experience.

TD-25
A new expression of analog listening.

The TD-25 is designed for those moments when the system disappears and the music takes over. Its solid walnut plinth brings warmth, stability, and a natural sense of balance, creating a listening experience that feels effortless, immersive, and deeply connected to the recording.

Behind that experience is a design focused on precision and silence. A high-mass aluminum platter, machined from a single piece, rotates on a self-lubricating bearing with a ceramic contact point, maintaining exceptional speed stability and allowing music to unfold with natural flow.

The motor is mechanically isolated from the playback platform to minimize vibration, while the low-resonance unipivot tonearm follows the groove with remarkable freedom and precision. Every adjustment serves a simple purpose: helping the cartridge retrieve more of what was captured in the recording.

The TD-25 is not about hearing more details. It is about feeling closer to the music, the musicians, and the intention behind every performance.
