Brioso PHPA1

Hi-end amplification, made compact

ELISA in your pocket

ELISA is the patented system by AUDMA designed to recreate the primary interaural time difference of loudspeaker listening within headphones.
It enables precise spatial control through the STAGE and ANGLE parameters, allowing precise adjustment of spatial perception based on the source material and listener preference.

Discover ELISA

ELISA is fully integrated into Brioso PHPA1, AUDMA’s portable headphones amplifier, and ensures consistent spatial reproduction with precise and real-time control.

Design

Brioso PHPA1 brings the full ELISA experience into a compact portable form, designed to combine premium refined engineering with everyday usability.

Crafted from a solid aluminum chassis with an anodized finish, the Brioso offers structural rigidity and a premium tactile feel. Two silicone grip bands enhance stability and keep the unit secure during portable use.

Its pocket-sized design makes it a genuine Hi-end portable amplifier ready to deliver uncompromised performance wherever you go.

Performance

The BRIOSO PHPA1 delivers precise and stable amplification across a wide range of headphones, from the most sensitive IEMs to the most demanding dynamic and planar magnetic headphones.

All inputs follow a unified signal architecture, ensuring consistent behaviour and reliable compatibility across sources. Both analog and digital inputs are processed by the AKM AK4499EXEQ and AK4191EQ, with support for high-resolution playback.

The rechargeable lithium battery ensures up to 5 hours of listening time for extended portable use. The segmented LED indicator displays the battery level.

Control

The BRIOSO allows easy adaptation to different listening scenarios through direct access to ELISA parameters. Stage adjusts perceived distance, while Angle defines width. The Bass control optimizes the response based on the headphones used.

These push-pull potentiometers remain flush with the chassis when not in use, preserving a clear and compact design.

The rotary knob controls power on/off and volume adjustment. ELISA can be activated with a dedicated button with LED indication (that provides immediate visual feedback): blue when off, amber when engaged.

Thanks to the rear switches you can ensures proper matching between source and headphone sensitivity, in order to maintain a dynamic range while keeping a low noise floor.
