DHT/300

Master DHT/GaN FET Power Amplifier

Where tubes and solid state sing together

The Master DHT/GaN FET Hybrid utilizes some of the latest GaN FET Class D technology. Paired with an enhanced version of our DHT balanced input tube circuit feeding a 300 wpc output stage, it provides both tube richness and dynamic control. 


Overview

The Master features our rather unique DHT tube input stage capable of running the 45, 2A3 or 300B. Sporting a lively triode tube stage feeding the 300 watt GaN Fet amplifier stage which in turn delivers powerful and dynamic sonic performance with just  the right amount of tube euphonics to breath new life to your system. 

The Master provides both balanced and single ended inputs as well as a 3 position [gain] switch on the rear panel. Low, medium and high gain are available to better match the amplifier with the rest of your system.
