Leak
A British Hi-Fi Legend, Restored
Harold Joseph Leak founded H.J. Leak & Co. in London in 1934. Over the following three decades, the brand became one of the defining names of the British hi-fi boom — responsible for a series of engineering firsts that still resonate in audio design today. In 1945, Leak released the Type 15 amplifier, the first of its "Point One" series — the first amplifiers ever to reduce total harmonic distortion below 0.1% at rated output, at a time when 2% was considered acceptable. In 1948, the TL/12 followed, achieving such accuracy that it was adopted as a BBC standard by 1951. In 1955, the Trough-Line FM tuner — still considered one of the finest FM tuners ever made. In 1961, the Sandwich loudspeaker pioneered true piston-cone action using polystyrene foam bonded between aluminium skins. In 1963, the Stereo 30 became one of the first transformerless transistor amplifiers, a circuit topology that underpins every solid-state amplifier made since. Leak sold to the Rank Organisation in 1969. Competition from Japanese mass-market manufacturers eroded the brand through the 1970s, and production eventually ceased. For four decades, Leak existed only in the memories of audiophiles and the second-hand market. In 2020 — the year of Harold Leak's 113th birthday — the IAG Group revived the brand. The Leak Stereo 130 and Stereo 230 integrated amplifiers and the CDT CD transport carry the original art-deco aesthetic forward into the present, pairing period-inspired design with contemporary circuit engineering and digital inputs.
