It’s a fairly balanced buyer’s market for this category, and this one lands right at the middle of it: at £157, it’s essentially on top of the £156 median and comfortably below the £252 75th percentile, so this reads as a fair buy rather than a bargain or a stretch. With 54 recent comparables behind it, the price is well-anchored and not asking for a premium just to get in the door.
That makes it appealing if you want a clean, no-drama headphone amp from a respected British maker known for a smooth, low-noise presentation and easy-to-live-with musicality. At this price, the main upside is simply getting a well-regarded unit without paying collector money; if it’s tidy and fully working, there’s little reason to overthink it. Just confirm the usual basics—power supply, scratch-free controls, and stable left/right balance—but nothing here suggests a red-flag listing.
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.
