M10 preamp and AZN-S7C step up available as well listed separately. 5F8y. 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 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 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 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.

Proudly created with When you consider the price of a power amp, it's interesting to calculate the cost per watt. In that light, the Gaku-On monoblock from British maker Audio Note and distributed in the US by Audio Federation is the most expensive power amp I know of. The Gaku-On's output is relatively high for a tube-based amplifier—45 watts, which might seem skimpy compared with big solid-state amps, but it's more than enough to get plenty of volume from high-efficiency speakers. The directly heated single-ended triode SET design operates in class A mode, which means the entire waveform is amplified by the same compliment of tubes—in this case, two NOS VT4-C/211s per channel operating in parallel. One of the beauties of SET amps is their simplicity, an approach that is fully embraced in the Gaku-On. Its zero-feedback, transformer-coupled circuit topology uses custom-designed transformers that are hand wound with Audio Note's silver wire, and the other components are the highest quality available with as few as possible in the signal path. At $185,000/pair, the price per watt comes to $2056, which is almost double the result of the same calculation for the Wavac SH-833 $350,000 for two channels of 150W each, or $1167 per watt. Which is better? I'm sure it's a highly subjective call. If you're planning to drop that much coin on power amps, you'd better give both a careful audition with the speakers you intend to use with them to determine which one you prefer. Audio NoteTM balanced, transformer coupled mono power amplifiers - First PrinciplesThe shortest signal path is generally the best, this is the professed aim of almost all the manufacturers of high quality amplification in the audio industry. However, when it comes to executing this ideal, most of the rest of the industry has been wilfully forgetting this truth and has become addicted to complexity and technology as marketing statements, in stark contrast to this Audio NoteTM has continued to focus on studying and refining our understanding of how to achieve the above goal in order to create products that deliver better and more realistic music, lasting value and overall quality. Unsurprisingly, the more we explore, the more it becomes obvious that simplicity – and in particular keeping passive components completely out of the signal path or at least to an absolute minimum – is desirable for better and more faithful music reproduction. Our ideas eventually led to a decision to develop a better sounding power amplifier circuit, a potential successor to the original parallel single-ended 211 based Gaku-On. In pursuit of ultimate simplicity, we decided that it would comprise just two active stages and three transformers; one on the input, one as a driver and one on the output. This topology reduces the number of passive parts in the signal path to just two resistors. Designing the circuit was relatively easy on paper. However when we came to building a prototype we discovered why such nothing like it had been implemented before, and it was more than half a decade before we could bring the new Gaku-On to fruition. Our finding was that such a simple amplification circuit demands a degree of transformer quality never seen before in professional or domestic audio. Audio NoteTM is unique in our facility to design, model, prototype and wind our own transformers in house, yet in spite of this it took even us six years to research and develop the necessary materials know how to achieve a musically transparent magnetic coupling from input to output in such a simple circuit. Each transformer has to be complimentary in every aspect of behaviour to the one next in line. It must not impose any bandwidth, phase, linearity or low level abnormalities which can be amplified by the following stage or stages. It was no small task getting to a point where each transformer was as invisible as the next, despite differences in core size, design and passing signal level.

In the event, the new Gaku-On has repaid our efforts and sets a fresh benchmark in audio amplification at the top of Audio Note TM Performance Level Five. The circuit topology cannot be bettered, simplicity cannot be taken any further than this, the valve choice, a directly heated VT25 driver with a pair of paralleled VT4-C/211 directly heated triodes as power valves, will be hard to improve on as well, so all that remains would be to develop even better components parts, materials and transformers. In order to beat this we will continue to research and develop our understanding, and until we find the necessary solutions to further improve the materials, simply put, we believe nothing will come along that beats it. Everything we learned in the process of developing the Gaku-On we have applied subsequently to a new and partnering family of balanced, transformer coupled monoblock amplifiers. The P4 Balanced, Ginrei, Baransu Balanced, Kageki Balanced and Kegon Balanced are each an expression of the simplest circuit and purest musicality that we believe can be achieved at Audio Note TM Performance Levels Three, Four and Five. ​ Please choose from the icons above to discover more...
