Description
AUDMA MAESTRO HPA1 | Reference Hi-End Headphone Amplifier
The Art of Sound, Perfected
The AUDMA MAESTRO HPA1 stands as the reference amplifier of the AUDMA lineup — a masterful union of cutting-edge engineering, Italian craftsmanship, and artistic design. Featuring ELISA, AUDMA’s patented soundfield technology, it recreates the three-dimensionality of real room listening through headphones with stunning precision.
Italian Heritage, Audiophile Precision
Designed and built entirely in Italy, the MAESTRO HPA1 represents decades of research, passion, and a relentless pursuit of sonic purity.
Every component is selected with audiophile-level rigor — from its dual-mono power supply to VELVET SOUND™ DACs, precision connectors, and tactile analog controls. The result is a system that delivers a natural, dynamic, and emotionally engaging listening experience.
ELISA Technology — Spatial Sound Redefined
The ELISA circuitry (Enhanced Listening Image Spatial Adjustment) is AUDMA’s patented innovation, engineered to reproduce the depth, realism, and acoustic dimension of speaker-based listening.
It allows listeners to experience true 3D sound immersion through headphones — with lifelike width, height, and spatial precision.
Functional Beauty, Crafted in Aluminum
Each MAESTRO HPA1 is a work of precision design. Its chassis, machined from solid aluminum, offers not only elegant aesthetics but also superior electromagnetic shielding, ensuring an ultra-clean and stable signal path.
The Luxury Edition features embossed side grilles, an engraved AUDMA logo, and refined finishes — achieving the perfect harmony of art and technology.
Intuitive Controls & Analog Expression
Semi-circular dual V-meters, with discreet backlighting, merge analog elegance with precision functionality.
Each meter simultaneously displays channel VU signals and ELISA-processed data, providing visual insight into both performance and sound imaging.
Ambient-sensitive lighting dynamically adjusts to the room’s brightness, while softly illuminated knobs ensure effortless operation in any environment.
Versatile Connectivity
With both analog and digital inputs, the MAESTRO HPA1 adapts seamlessly to any source — vintage or modern.
-
Analog Inputs: RCA (unbalanced), XLR (balanced)
-
Digital Inputs: Coaxial (RCA), Optical (TOSLINK), USB 2.0
-
Outputs: LINE XLR / RCA, Pentaconn, 6.3mm jack, and XLR 4-pin
Whether driving high-end headphones or connecting to an external Hi-Fi system, the MAESTRO HPA1 ensures flawless signal integrity.
Remote Control — Precision in Your Hands
A beautifully finished remote control provides full command of power, volume, mute, ELISA activation, stage, and angle — combining ease of use with Italian refinement.
