AGD DUET

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

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 is rated 300W 4Ω . To achieve these performances in such compact CNC machined cabinet (available fully polished or anodized black), we have designed a new power supply by utilizing the most advanced HV GaN MOSFET available in the market today.
 

For the AGD 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.
 

To maintain with time the full value of the product , key characteristic of all AGD amps, the GaN-based power stage module utilized in the AGD “DUET” is fully upgradable to next generation GaN-Power modules with new GaN MOSFET devices with advanced performances.

Engineered with audiophile-grade components — premium drivers, hand-matched crossovers, and a hardwood enclosure tuned for natural decay. Every cabinet is internally braced and damped to suppress resonance below the threshold of audibility.

• Custom 6.5" mid-bass driver with paper-pulp cone for transient accuracy.
• Soft-dome silk tweeter with neodymium motor for airy, fatigue-free highs.
• Point-to-point hand-wired crossover using silver-foil capacitors.
• Bi-wirable terminals plated in pure copper.

Place each speaker on its dedicated stand, toed-in toward the listening position. The hardwood enclosure resonates in concert with the drivers — a deliberate, musical interaction rather than a flaw to be eliminated.

Connect to a quality amplifier using bi-wired speaker cable for the most transparent presentation. Allow 50–100 hours of break-in for the drivers and crossover capacitors to settle into their final voicing.
