The legendary Oto SE receives its first major technical revision in decades, featuring bespoke in-house components and a redesigned power supply.<\/p>\n

WEST SUSSEX, UK \u2014 Audio Note (UK) is pleased to announce the release of the Oto SE 35, a significant update to one of the most enduring integrated amplifiers in high-end audio. The release marks 35 years of continuous production for the Oto, which has been a cornerstone of the Audio Note (UK) range since its debut in 1991.<\/p>\n

\"\"<\/p>\n

Originally conceived by Audio Note (UK) founder Peter Qvortrup and designed by Andy Grove, the Oto was the first amplifier to be fully developed and manufactured by Audio Note (UK). While the Audio Note name was already well known, thanks to the legendary Ongaku integrated amplifier, the Oto proved that the company\u2019s philosophy of musicality and vacuum tube refinement could be successfully applied at more accessible price levels.<\/p>\n

Peter Qvortrup explains, \u201cWhen I set Andy the challenge to design a single-ended [SE] pentode version of the Oto in the early 90s, single-ended amps were a big outlier. The Oto and now the Oto SE 35 stand as a testament to our philosophy on timeless quality audio design. We still maintain and service our customers’ Oto\u2019s, making sure they’re good for years to come. This is what true longevity looks like, and that will never change.\u201d<\/p>\n

\"\"<\/p>\n

\u201cOver the last three decades, the design of the Oto has undergone various evolutions,\u201d says Chief Designer Andy Grove. \u201cI decided it was time to give the Oto SE a complete makeover. The result is an amplifier with a more realistic ‘bass kick’, the kind of physical presence you feel when you are in the room with a kick drum or a bass guitar. It remains an all-round musical, fun-to-live-with amplifier, but it can now summon a serious amount of attitude when the recording demands it.\u201d<\/p>\n

The Oto SE 35 integrated amplifier (and the P1SE 35, the stereo power amplifier version of the OtoSE) are available to order now through all authorised Audio Note (UK) specialists.<\/p>\n
