HiFi Knights has published its review of Allegro, AGD Productions’ first all-in-one design, and awarded it the Victor — a distinction the publication reserves for the few components it considers exceptional. Allegro is the second AGD product to earn it, following the Audion Vivace monoblocks.
Reviewer Dawid Grzyb evaluated Allegro the way most owners will actually use it: as a complete platform. It replaced nearly his entire reference chain — Innuos Statement Next-Gen server, LampizatOr Horizon360 DAC, Trilogy 915R preamplifier and 995R monoblocks — a front end he estimates at approximately nine times Allegro’s price.
Driving the notoriously demanding Boenicke W11 SE+ floorstanders, Allegro’s grip on the low end suggested a damping factor well into triple digits. Paired with sound|kaos Vox monitors — speakers Grzyb reports normally require his Class A monoblocks to open up — he described spatial performance he had not expected from a Class D design.
Allegro combines a fully discrete in-house R-2R DAC, a proprietary quad-core streaming platform, MM/MC phono stage, Class A headphone output and 125W per channel into 8Ω (250W into 4Ω) within a 280 × 280 × 90mm aluminium enclosure. Power comes from AGD’s 600W gallium nitride switching supply, the same new-generation platform now used in Forté and Gran Vivace Mk IV, with the GaNPower output stage switching at approximately 800kHz.
Grzyb concluded that he knows of no competing all-in-one performing at this level.
