These allow us to exert extremely tight control over the performance and voicing of the complete amplifier from input to output, something that is simply beyond the possibilities of manufacturers who have to rely on 'off the shelf' components. The circuit is now a beautiful example of elegant simplification, something that could only be realised thanks to our ability to create extremely closely matched transformers in-house, and having our own supply of custom resistors, in-house made foil capacitors and custom made electrolytic capacitors. The output transformers for the new MEISHU were designed specifically for the project by Andy Grove, and it is not an overstatement to say that they are superb. This is the most important, fundamental upgrade over the original design.
#Audionote amplifier driver#
The input and driver stage is very similar to that found in the JINRO, TOMEI and ONGAKU, with a 12AU driving an in-house designed and manufactured inter-stage transformer for the best energy transfer, evenness and authority. When this arrangement is optimised, it works extremely well, producing a very homogeneous and ‘complete’ sound. The new PSU uses only one mains transformer, one 5U4 rectifier valve and one choke. This is exactly what we have done with the MEISHU Tonmeister.
So to create a better amplifier, the natural idea was to simplify the circuit and optimise every element, so the combination works seamlessly and harmoniously together.
The same is true for an amplifier circuit if each stage is not absolutely correctly chosen and matched to work optimally with the rest of the amplifier, the result will be blurred, unfocused, uneven sound lacking in information. If the lenses in a microscope are not correctly chosen and adjusted, the image becomes blurred, and detail and information is lost.
As with what we learned developing the 211 amplifiers, each element in a circuit is like each lens in a microscope, and has to be perfectly chosen and formed to correctly work with the proceeding and following lenses (or stages in the amplifier circuit).
