Single Ended
Part selection is optimised to realise the most neutral and realistic sonic reproduction.
Some of the superior quality components utilised in the OTO SE include: –
Aluminium foil, paper in oil 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 OTO SE to produce impressively extended and controlled bass.
Some of the superior quality components utilised in the OTO 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 OTO SE Signature to produce impressively extended and controlled bass.
The OTO SE fulfils all Audio Note (UK) Level 2 criteria: -
