Founded in 1934 by Harold Joseph Leak, pioneering British hi-fi manufacturer LEAK was a mid-twentieth century trailblazer in the field of high-performance audio equipment.

LEAK has been responsible for many technological firsts. For example, the Point One series of valve amplifiers (1945) were the first to reduce total harmonic distortion to 0.1 per cent, and the ground-breaking Trough-Line FM radio tuner (1955) is still considered one of the finest FM tuners ever made.

LEAK’s Sandwich speakers (1961) heralded true-piston cone action by sandwiching polystyrene foam between outer skins of stiff aluminium foil. And the Stereo 30 all-transistor amplifier (1963) spearheaded the use of transformerless transistor output stages over then-standard transformer-coupled designs, thus paving the way for future solid-state amps.
