The Gaku-On Mono Power Amplifiers are positioned as the flagship mono amplifiers in the Audio Note (UK) lineup, representing the pinnacle of their amplifier range. These amplifiers are designed and produced with meticulous attention to detail, and no expense is spared in their construction.

The Gaku-On are Pure Class A Parallel Single-Ended  (SE) valve amplifiers. These amplifiers utilize a pair of 211/VT4-C triode valves per chassis. The 211 is a power triode tube widely regarded for its sonic characteristics and ability to deliver high-quality audio performance. By using a parallel single-ended configuration, Audio Note maximizes the power output and efficiency of the amplifiers while maintaining a pure Class A operation.

These Mono Power Amplifiers are meticulously engineered to prioritize sonic performance rather than technical specifications and meet all the Level 5 criteria established by Audio Note (UK), which ensures a high standard of audio quality. The Level 5 criteria includes Pure Class A Operation, Zero Negative Feedback, Single-Ended Output Stage, Valve Rectification, and Directly Heated Triode Operation. 

Audio Note (UK) prides itself on using the finest components available to achieve the highest level of performance. Consequently, the following premium components are incorporated in the Gaku-On Mono Power Amplifiers. First, Black Gate Capacitors, which are highly regarded for their ability to enhance the sound reproduction by providing precise and detailed audio. Audio Note (UK) Silver Foil Capacitors, known for their transparency and natural sound reproduction, are also part of the structure of these very unique power amplifiers. Tantalum Resistors, who are known for their stability and low noise characteristics, ensures accurate signal processing and minimizes unwanted noise or distortion. In addition, Silver wiring is used for signal transmission throughout the circuit. Silver is known for its excellent electrical conductivity, which helps in maintaining signal integrity and minimizing signal loss. Finally, the Gaku-On Mono Power Amplifiers incorporate the finest core materials available. High-quality transformer cores contribute to better energy transfer, resulting in improved performance and sound quality.

Overall, the Gaku-On Mono Power Amplifiers are engineered to provide exceptional sound reproduction, with a focus on accuracy, clarity, and musicality. The incorporation of the premium components in these Mono Power Amplifiers reflects Audio Note (UK)’s commitment to delivering the highest level of audio performance. However, it is important to note that the specific component selection and implementation may vary across different versions or iterations of the Gaku-On amplifiers.
