Audio Note (UK) Marks 35 Years of the Oto Integrated Amplifier with Anniversary Edition

Audio Note (UK) has released the Oto SE 35, an anniversary edition of its iconic Oto integrated amplifier, celebrating 35 years of continuous production. First introduced in 1991, the Oto was the company’s first fully in-house amplifier and helped establish Audio Note’s philosophy of musical, single-ended tube design at a more accessible level.

The new Oto SE 35 features its first major technical update in decades, including bespoke in-house components and a redesigned power supply. According to Audio Note’s designers, the update delivers stronger, more realistic bass while preserving the musical character that made the Oto a classic. The Oto SE 35 and its power amplifier counterpart, the P1SE 35, are now available.
