AUDMA BRIOSO PHPA1 | Portable Hi-End Headphone Amplifier

Hi-End Amplification, Made Compact

The AUDMA BRIOSO PHPA1 redefines portable audio by delivering hi-end amplification in a compact and functional form factor. Designed and handcrafted in Italy, the PHPA1 integrates ELISA circuitry, a patented sound-shaping technology that allows precise control over the spatial characteristics of your music — ensuring lifelike imaging and natural presentation wherever you listen.

Italian Design, Precision Engineering

Built with the same attention to detail found in high-end desktop amplifiers, the BRIOSO PHPA1 merges elegant craftsmanship with exceptional performance.
Its anodized aluminum chassis with a silk-effect finish, anti-slip rubber inserts, and push-pull potentiometers reflect both durability and sophistication. Compact yet robust, it’s made for discerning listeners who demand performance and style in one.

ELISA Circuit Technology

At the heart of the PHPA1 lies ELISA, AUDMA’s proprietary circuit designed to shape and stabilize the sound image with unmatched accuracy. This exclusive feature enables precise spatial positioning and natural soundstage reproduction, offering an immersive listening experience that adapts to your environment and headphones.

Analog & Digital Excellence

Supporting both analog and digital inputs, the PHPA1 offers remarkable flexibility for a wide range of sources.
Digital-to-analog conversion is powered by AKM’s flagship AK4499EXEQ and AK4191EQ DACs, leveraging VELVETSOUND™ technology for ultra-low distortion, exceptional transparency, and natural tonal balance.

Versatile Power Delivery

The PHPA1 is designed to drive headphones of varying impedance and sensitivity levels with confidence. Rear-mounted switches allow users to adjust output power, ensuring optimal control and performance across all headphone types — from sensitive IEMs to demanding planar magnetic models.

Compact, Functional Control

For convenience and ergonomic efficiency, STAGE, ANGLE, and BASS controls are seamlessly integrated into the top panel. This intuitive layout keeps control at your fingertips, maintaining a clean, compact design that complements its portable nature.
