The OTO SE integrated amplifier uses EL84 valves in parallel single ended configuration, producing an output of 10 watts and is available with or without an internal an all valve MM phono stage. It’s all housed within the classic Audio Note casework which is available with either a black acrylic or brushed aluminium fascia. As you’d expect with a good single ended amplifier the sound is punchy and dynamic, whilst still being very natural and expansive. It may lack the completely grain less mid band of a 300B SE amplifier but it’s an exceptionally neat package and so involving to listen to that dissecting the minutiae of its performance seems to be missing the point. The phono stage is a very good quality design too, and not simply an afterthought like many. A fractionally more powerful push pull version is available, but we would always recommend this SE version for the best sound quality.

Some of the superior quality components utilised in the OTO 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 OTO SE to produce impressively extended and controlled bass.
