At £260, this is a strong deal: it sits exactly at the 25th-percentile asking price in the 24-listing sample, versus a median of £286 and a 75th percentile of £310. For a correctly identified, working LK140, that is bargain territory rather than merely fair value.
The LK140 remains a very capable, compact power amplifier, offering clean, controlled, rhythmically precise sound and useful drive into demanding speakers. It delivers roughly 95 watts per channel into 8 ohms and 140 watts into 4 ohms, with protection against overload and overheating. Given the unknown condition, confirm both channels operate cleanly, the unit powers up without hum or relay problems, and the speaker terminals and casework are sound; at this price, a successful test makes it an easy recommendation.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Linn Products: Brand Overview
Linn Products was founded in 1973 by Scottish engineer Ivor Tiefenbrun in Glasgow as a vehicle to manufacture the Sondek LP12 turntable, which would become the company's most iconic product and a cornerstone of high-fidelity audio. The brand emerged during the golden era of British hi-fi with a revolutionary "source first" philosophy—challenging the prevailing industry belief that loudspeakers mattered most by demonstrating that superior sound quality begins with the audio source. This foundational principle has guided the company's engineering ethos for over five decades.
Linn's product portfolio spans the complete hi-fi chain, from turntables and tonearms to preamplifiers, power amplifiers, and loudspeakers. The company introduced the world's first microprocessor-controlled preamplifier and power amplifier in 1985 (the LK1 and LK2), establishing itself as an electronics specialist. From 2007 onward, Linn pivoted toward digital music streaming, becoming an early adopter of network-based audio playback supporting studio master-quality recordings at 24-bit/192 kHz resolution, and discontinued CD player production in 2009 to focus on this strategic direction.
Linn occupies the high-end segment of the audio market, commanding respect among discerning audiophiles and collectors for its uncompromising engineering approach and longevity. The brand's reputation rests on meticulous product design, acoustic isolation principles, and a commitment to eliminating weak links in the signal chain—a philosophy that has made Linn one of the most influential manufacturers in hi-fi history and a benchmark for quality-focused audio engineering.
