The Audio Note (UK) Neiro Mono Power Amplifiers are Pure Class A Parallel Singled Ended valve amplifiers that use a pair of the highly regarded 2A3 triode valves per channel, producing a level of performance that is radically superior to the vast majority of current designs.
They have been specifically engineered for sonic performance rather than technical specification, and fulfil all Audio Note (UK) Level 4 criteria: -

-Pure Class A operation
-Zero Negative Feedback
-Single Ended Output Stage
-Valve Rectification
-Directly Heated Triode operation
-Materials and component quality
​
Each amplifier is completely hand assembled, and uses only the finest possible materials and components:
​-Audio Note (UK) customer Output Transformers, using AN(UK) Copper primary windings, AN(UK) Silver secondary windings and AN(UK) UHiB double C cores
-Audio Note (UK) custom 1 Watt Tantalum resistors
-Audio Note (UK) Copper Foil capacitors
-Audio Note (UK) Silver internal wiring
-Black Gate capacitors in critical areas
