Details
The Audio Note (UK) SORO Integrated Amplifier is Pure Class A, producing an outstanding level of performance.
The SORO is available in a Push-Pull or Single Ended valve design.
Push Pull
It has been specifically engineered for sonic performance rather than technical specification, and fulfils all Audio Note (UK) Level 1 criteria: -
Pure Class A Push-Pull Pentode operation
Materials and component quality
A 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. This arrangement allows for a passive line stage / volume control circuit to be incorporated into the design.
The output transformers are custom designed and manufactured by Audio Note (UK), and are of the highest possible quality.
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.
Single Ended
Part selection is optimised to realise the most neutral and realistic sonic reproduction.
Some of the superior quality components utilised in the SORO SE include: -
Audio Note (UK) foil capacitors, used in the most critical areas. Dual power supplies and transformers, one for the output stage and one for the remaining circuitry. Custom designed output transformers, manufactured by Audio Note (UK). These output transformers—one of the most critical areas of valve amplifier design—allow the SORO SE to produce impressively extended and controlled bass.
Some of the superior quality components utilised in the SORO SE Signature include: -
Audio Note (UK) Copper foil capacitors used in the most critical areas. Audio Note (UK) Tantalum resistors used in the most critical areas. Custom designed IHiB output transformers, manufactured by Audio Note (UK). 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.
