AGD “DUET” MonoBlock GaN-Based Amplifier


The AGD “DUET” MonoBlock Amplifier, is the newest addition to our state of the art Hi-End Power Amplifiers family.


June 8, 2023 - The AGD “DUET” is our first compact MONOBLOCK Amplifier utilizing 100% Gallium Nitride Power MOSFET design for both the output power stage and the power supply.


The AGD DUET MONOBLOCK uses the same fundamental technology pioneered with the AGD Gran Vivace, AGD TEMPO, AGD AUDION, the first true Hi-End amplifiers based on Gallium Nitride power MOSFET. The NEW GaN-Power output stage, based on a new set of discrete high voltage GaN MOSFETs, can operate up to 800kHz and at elevated slew-rates delivering the most sublime sound thanks to its ideal “by the book” oscillations-free switching performances.


The AGD “DUET” is rated 300W 4Ω.
“To achieve these performances in such compact CNC machined cabinet we have designed a new power supply by utilizing the most advanced HV GaN MOSFET available in the market today. For the DUET we also designed a new mother board with low noise linear supply rails and a superlative analog buffer stage based on AD797 op amps.” says Alberto Guerra, CEO of AGD Productions, Inc.
The AGD “GaNSound” Module is easily removable for future upgrades and has an additional copper heat-spreader to maintain the most stable temperature during operation.


“Also with the AGD DUET we have retained the key fundamental feature of upgradable GaNSound power module. This is a key feature AGD has maintained with all amplifier designs, from the Audion to the Gran Vivace, the Tempo and now the DUET. At AGD we firmly believe the customers have the rights to maintain the value of their investment, therefore we enable the possibility to upgrade the GaN output stage module at time when a new GaN MOSFET delivers the incremental performance and technological improvement” added Alberto.


The AGD “DUET” is available with a standard finishing anodized Black or fully polished,
Delivery of the AGD DUET, commence in September 2023 with MSRP of $11,500.
