MAESTRO HPA1

---

The amplifier that transforms listening into emotion.

The MAESTRO HPA1 is AUDMA’s reference-class headphone amplifier, designed and built in Italy to deliver an unparalleled listening experience. Featuring ELISA, a patented technology that recreates the three-dimensionality of real room acoustics in headphones, MAESTRO HPA1 transforms music into pure emotion.

Uncompromising Audio Performance

Every component inside the MAESTRO HPA1 is chosen with audiophile precision. From the dual mono power supply to VELVET SOUND™ DACs, each element is engineered to ensure absolute clarity, dynamic range, and tonal accuracy. This amplifier adapts effortlessly to any source, whether analog or digital, offering a listening experience that is natural, engaging, and profoundly musical. It’s not just amplification—it’s a complete system designed for those who demand perfection.

Italian Design Meets Functionality

The MAESTRO HPA1 is as beautiful as it is powerful. Its design reflects a philosophy where aesthetics and performance coexist harmoniously. Clean lines, premium materials, and meticulous craftsmanship make it an object of admiration. The semi-circular analog V-meters, with arc scales and discreet backlighting, are more than a style statement—they provide real-time visual feedback of the audio signal, including ELISA processing. Dynamic lighting automatically adjusts to ambient brightness, ensuring optimal visibility in any environment, while courtesy backlighting on the knobs makes operation intuitive even in low-light conditions.

Precision in Every Detail

Every aspect of the MAESTRO HPA1 is crafted for ergonomic excellence and tactile pleasure. The solid metal knobs, finished with an exclusive soft-touch treatment, offer a velvety feel that makes every interaction satisfying. From the placement of front controls to the robustness of the chassis, every detail is a deliberate choice aimed at enhancing usability and durability. This is a product where engineering meets artistry—where every gesture feels natural and precise.

Connectivity Without Limits

Versatility is at the heart of the MAESTRO HPA1. It features two stereo analog inputs (unbalanced RCA and balanced XLR) and three digital inputs (USB 2.0, coaxial, and optical), ensuring compatibility with both modern and vintage sources. Outputs include LINE XLR or RCA for integration with Hi-Fi systems, TVs, or other amplifiers, and multiple headphone connections via Pentaconn, 6.3 mm jack (with mini-jack adapter), and XLR 4-pin. This flexibility makes the MAESTRO HPA1 a central hub for any high-end audio setup.

Premium Remote Control The included remote control is as refined as the amplifier itself, offering complete and intuitive management of power, volume, mute, ELISA activation, stage, and angle adjustments. It combines practicality with elegance, ensuring that control is always at your fingertips.
