Our Thoughts RADAR AI

At £649, this lands right on the median of the recent GBP comps, so it reads as a fair, market-rate ask rather than a bargain or an ambitious outlier. With the 25th percentile at £350 and the 75th at £1,114, the price sits neatly in the middle of the normal used spread, which is exactly where a clean, working example should be if it’s not especially complete or exceptional.

That makes it a sensible buy if the condition checks out, because this is a well-regarded classic Leak stereo amp with the sort of build and presentation that still appeals to tube fans looking for a musical, compact power amp. The upside here is in originality, service history, and cosmetic honesty: if it’s unmolested, quiet, and ready to run, a fair-price listing can be a very nice way into a proper vintage piece.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About LEAK Stereo

Founded in 1934 by Harold Joseph Leak in London, England, LEAK emerged as a pioneering force in British hi-fi, initially crafting public address systems and cinema amplifiers before pivoting to high-fidelity home audio amid post-war innovation. With engineer Ted Ashley's contributions, the brand rode the 1950s hi-fi boom, producing landmark valve amplifiers like the TL/12 series, which set benchmarks for low distortion and performance, establishing LEAK as a global leader in affordable excellence.

LEAK specialized in integrated amplifiers, such as the iconic Stereo 20, Stereo 30, and Stereo 50, alongside innovative loudspeakers featuring the patented "Sandwich" foam-core drivers for precise bass and clarity. The lineup extended to radio tuners, pickups, tonearms, and turntables, blending valve warmth with emerging transistor tech to dominate the stereo era.

Acquired by the Rank Organisation in 1969 and dormant by the late 1970s amid Japanese competition, LEAK's revival under the IAG Group since 2020 honors its heritage with modern classics like the Stereo 130 and 230 integrated amplifiers, plus CD transports and streamers. Revered by vintage collectors for cult models like the Stereo 30, it holds mid-tier prestige today—delivering high-end British sound at accessible prices for discerning buyers seeking timeless refinement.
