PWM stage and output filter re-engineered with more advanced materials and new design techniques. Sold in Pair.
Introducing the new AGD “GaNTube88MkIII” – a culmination of two years’ relentless development and an unwavering commitment to acoustic perfection. This latest iteration marks a significant leap forward in sound quality, a result of tireless refinement and long hours of attentive listening.
Central to this advancement are two fundamental components of the GaNTube amplifier module: the PWM stage, (specifically the Voltage-Time converter block), and the output filter – now entirely re-engineered with more advanced materials and new design techniques.
The “GaNTube88MkIII” retains its 800KHz operating frequency, but with dramatic improvements.
The PWM and LC stages have been meticulously enhanced, resulting in reduced distortion, lowered noise, expanded bandwidth, and lightning-fast response times.
Rated at 250W 4Ω, the “GaNTube88MkIII” delivers its maximum RMS output power when paired with AGD Vivace MKII mono-blocks. With the AUDION MKII mono-blocks, the power is limited by the internal power supply, at 200W.
With the new MKIII, we have extended the frequency response of the power stage, now flat up to 60KHz, and by a combination of layout improvement and the re-engineering of the output filter, we managed to also significantly increase the slew rates performances.
This evolution enhances the sonic landscape, presenting an immersive musical journey literally out of this world.
