The legendary Audio Note Oto SE receives a major update, combining technical refinement and brand philosophy.
A Milestone in Audio Note History
The Audio Note Oto SE 35 marks 35 years of continuous production of the Oto integrated, and evolution in this new iteration. This anniversary edition represents a milestone for the brand, demonstrating its ongoing commitment to high-end audio, musicality, and vacuum tube refinement.
“The Oto and now the Oto SE 35 stand as a testament to our philosophy on timeless quality audio design,”
— Peter Qvortrup, founder of Audio Note UK
With its combination of classic single-ended design and modern technical updates, the Oto SE 35 continues to exemplify Audio Note’s philosophy: products that are built to last and deliver lasting musical satisfaction.
Design and Technical Evolution
Originally designed by Andy Grove in the early 1990s, the Oto has been updated with careful consideration for both sound and reliability. The Oto SE 35 introduces:
- Redesigned power supply, improving stability and performance
- In-house output transformer, custom-wound for precise signal delivery
- Tweaks to the power amp board, enhancing bass presence and musical detail
“The amplifier delivers a realistic bass presence, the kind you feel in a room with a kick drum or bass guitar, while remaining an all-round musical and user-friendly device,”
— Andy Grove, Chief Designer
The Oto SE 35 is a Class A, parallel single-ended pentode design, using EL84 output valves, and remains one of the most reliable and enduring integrated amplifiers in high-end audio.
Longevity and Philosophy
Beyond technical improvements, the Oto SE 35 embodies Audio Note’s philosophy of longevity and service. The company continues to support and maintain amplifiers built decades ago, ensuring customers can enjoy their systems for years to come.
This anniversary edition demonstrates that high-end audio is not just about performance, but also about identity, consistency, and respect for the listener.
