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. 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. Pure Class A Single Ended Pentode operationĪs 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). The SORO SE fulfils all Audio Note (UK) Level 2 criteria:. These output transformers – one of the most critical areas of valve amplifier design – allow the SORO Phono SE Signature to produce impressively extended and controlled bass. Custom designed IHiB output transformers, manufactured by Audio Note (UK). Audio Note (UK) Tantalum resistors used in the most critical areas. Some of the superior quality components utilised in the SORO SE Signature include: -Īudio Note (UK) Copper foil capacitors used in the most critical areas. These output transformers – one of the most critical areas of valve amplifier design – allow the SORO SE to produce impressively extended and controlled bass. ![]() Custom designed output transformers, manufactured by Audio Note (UK). Dual power supplies and transformers, one for the output stage and one for the remaining circuitry. ![]() Some of the superior quality components utilised in the SORO SE include: -Īluminium foil, paper in oil capacitors, used in the most critical areas. Part selection is optimised to realise the most neutral and realistic sonic reproduction. The power supply is a multi element design, ensuring precise operation of each circuit stage, whilst a DC supply feeds the low level valve filaments. The output transformers are custom designed and manufactured by Audio Note (UK), and are of the highest possible quality. This arrangement allows for a passive line stage / volume control circuit to be incorporated into the design. It has been specifically engineered for sonic performance rather than technical specification, and fulfils all Audio Note (UK) Level 1 criteria: -Ī high gain power amplifier stage is used consisting of an ECC82 dual triode acting as an anode follower for the first stage, the output of which is applied to a second anode follower (ECC82) which feeds the parallel connected 6L6G output valves. The SORO is available in a Push-Pull or Single Ended valve design. The Audio Note (UK) SORO Integrated Amplifier is a Pure Class A, producing an outstanding level of performance.
