£99 is a strong deal against your own market data: it sits below the £137 25th percentile and well under the £158 median for recent comparable listings, so this is priced to move rather than merely “reasonable.”
That makes it an easy listen for a buyer who wants a compact, well-liked headphone amp without paying up. The Novo is generally respected for clean, unforced sound and sensible, no-drama usability, so the value here is in getting a proven Graham Slee box at a bargain-ish entry point. At this price, I’d mainly check that the unit powers up cleanly, the volume pot is quiet, and any PSU/cable situation is clear, but there’s no need to be fussy if the listing is otherwise straight.
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.
