At £53, this sits well below the £126 25th percentile and a long way under the £156 median for recent used GBP listings, so it reads as a strong bargain rather than a merely fair buy. Against typical second-hand demand, that is an unusually easy entry price for a known portable headphone amp with its mains adapter included.
The appeal here is straightforward: it’s a compact, well-regarded analogue headphone amp from a brand with a strong reputation for sensible, music-first design, and the included original power supply adds practical value. At this level, the main question is simply whether it powers up cleanly, runs quietly, and comes with the right leads for your setup; if those basics check out, this looks like a very decent pickup for someone wanting a tidy portable/flexible amp without paying much.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Graham Slee Projects, founded in 1998 in the UK by engineer Graham Slee, traces its roots to his extensive career beginning in 1974. Starting in audiovisual engineering, he advanced through printed circuit design, electronics manufacturing, and broadcast audio, serving as a senior engineer for BBC studio contractors before freelancing in hi-fi. This deep expertise laid the foundation for a brand dedicated to precision audio electronics, all handmade in British workshops.
The company specializes in phono preamplifiers and headphone amplifiers, developed in tandem since 2000 to mutually enhance performance. Flagship phono stages like the Accession MM, Reflex M, Era Gold V, and Revelation excel at extracting superior detail from vinyl, while headphone amps such as the Solo Ultra Linear and Novo deliver refined, high-fidelity drive. Graham Slee also offers DACs, focusing on compact, synergistic components for vinyl enthusiasts and headphone users rather than speakers, turntables, or cables.
Positioned as a niche boutique in the high-end hi-fi market, Graham Slee earns acclaim among discerning audiophiles for its uncompromised sound quality and value. Free from mass production, its products prioritize musical transparency and build integrity, appealing to serious vinyl collectors and headphone aficionados who seek understated excellence over hype.
