At £172, this sits essentially on the market median for recent comparable UK listings, so it reads as a fair, buyable price rather than a standout bargain or an overreach. With the 25th percentile at £104 and the 75th at £283, it’s comfortably in the normal used range for this type of portable Graham Slee gear.
That makes it a sensible pick if you want a well-made, genuinely audiophile-oriented headphone amp with a strong reputation for clean, unforced sound and proper drive from a compact battery-friendly design. The main upside is value-for-money at this level: if it’s complete, working properly, and includes any original extras, it’s the sort of listing that can be an easy yes for someone wanting quality without paying top-of-market money.

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.
