Linn LK140 Power Amp In very good pre-owned condition and good working order. Solid workhorse. 94 WPC into 8 OHMS.
The Linn LK140 is a revered, rugged stereo amplifier known for exceptional loudspeaker drive and pure sound, making this £450 asking price notably ambitious compared to the typical used market. With the ground truth median at £291 and the 75th percentile at £322, this listing sits well above the 75th percentile, suggesting an overpriced tag rather than a bargain. While the unit is described as good condition, the price is roughly £130 higher than the 75th percentile, so buyers should verify functionality and included accessories before committing.
Despite the high price, the LK140 remains a worthwhile buy for enthusiasts seeking robust power (95W into 8Ω, 140W into 4Ω) and the flexibility to build a custom system with one or multiple units. Its UK-made heritage and reputation for reliability offer meaningful upside, especially if the listing includes original cables or manuals. However, given the price exceeds the 75th percentile by a significant margin, only proceed if the condition is pristine and accessories are complete; otherwise, it may be prudent to wait for a fairer offer closer to the £291 median.
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.
