First to use the unique GaNTube™ technology with Gallium Nitride Power-Stage integrated into a Vacuum Tube, the AGD amplifiers are the most technologically advanced design available in the market today.

The AGD “Gran Vivace” is rated 400 W on 4 Ω and it is characterised by an outstanding 50 A peak output driving capability that will satisfy the most demanding loudspeakers and fill with musical sound pressure also the largest audio rooms.

To achieve these performances, we have designed a new GaNTubeTM component, the AGD GaNTube KT120, larger and more powerful than its sibling AGD GaNTube KT88 MKii.

Features

In this new AGD GaNTubeTM 120KT, a pair of powerful 600 V rated Gallium-nitride power MOSFETs are at the core of the design.

These new advanced components are the key to the reference level performance of the AGD “Gran Vivace” Monoblocks.

Thanks to the improvement in components, and PCB layout (tested and introduced recently with the AGD GaNTubeTM KT88 MKii), we achieved the goal to operate also this much larger power-stage at 800 kHz, with a direct and positive impact on the overall already outstanding sonic and musical performances.
