Condition is only listed as tested and working, which is the key green light here, and at £81 this is a strong bargain against the recent used market: well below the £125 25th percentile and far under the £155 median. That makes it look like an easy buy if it’s complete and functioning properly.
The Voyager is a respected portable amp: compact, battery-capable, and known for a clean, mature sound with enough refinement to lift decent headphones and insensitive earphones without fuss. For this money, the upside is strong, especially if it comes with the right power lead or battery setup; I’d mainly just confirm it powers from the intended source and that the volume control is smooth, since the price already feels generous.
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.
