AXPONA 2025 Luxury Hi-Fi Audio Show Report By Steven R. Rochlin

  AGD Productions is at AXPONA 2026 unveiling their Allegro, a compact all-in-one audio system that brings amplification, digital conversion, Hi-Res Audio music streaming, and analog phono stage playback together in a single chassis. Built around AGD's proprietary Gallium Nitride power stage, Allegro delivers 200 Watts per channel (stereo) into 4 Ohms, translating the company's award-winning amplifier circuitry performance into an easy-to-use integrated platform. The launch positions Allegro as a turnkey reference solution for listeners who want high-end sound without the complexity of multiple components and needing many cables.

At the heart of AGD's Allegro is a high-performance integrated amplifier based on their GaN technology paired with a discrete R-2R DAC for natural-sounding digital reproduction and a fully balanced phono stage supporting both MM and MC turntable cartridges. The system also includes network streaming compatible with leading platforms and Audirvăna certification, an analog preamplifier with line and balanced XLR inputs, and a fully balanced Class A headphone amplifier for head-fi'ers / personal listening. AGD says this architecture preserves the purity and speed of separate reference components while dramatically reducing footprint and cabling.

AGD engineers emphasized signal integrity and dynamic headroom in Allegro's design, citing a fully isolated digital architecture, ultra-low noise analog circuitry, and a high-speed switching power supply optimized with GaN MOSFETs that can deliver a very high peak power for short transients. The chassis feels very solid and is precision-machined aluminum for thermal stability and mechanical integrity, and the company highlights meticulous circuit layout to maximize resolution and micro-detail retrieval. Founder and chief designer Alberto Guerra described the goal as eliminating system complexity "while preserving absolute performance," aiming to deliver the speed, control, and musical realism associated with AGD's reference amplifiers. We here at Enjoy the Music.com have to agree 100%, and it's great to see these update options for us music lovers who invest in our gear.

Designed for modern listening spaces as well as dedicated systems, perhaps your home office, or your garage filled with auto-exotica, AGD Productions' Allegro aims to simplify setup without sacrificing high-end results that music lovers truly cherish. By reducing signal paths and potential degradation from multiple connections, we love this new all-in-one from AGD! The Allegro is available through AGD's webstore at $14,999, with distribution through the company's global dealer network to follow shortly.

As always in the end what really matters is that you...

 

Enjoy the Music,
