At £89, this is clearly below the £103 25th percentile for recent UK comparables, so it reads as a strong deal rather than a merely fair one against the typical £143 median. For the obvious alternative at this price, you’re usually looking at a generic budget headphone amp or a weaker DAC/amp combo; this is the sort of listing that lets you buy a better-regarded standalone amp for less than the market average.
The appeal is straightforward: Graham Slee gear has a solid reputation for clean, low-noise, musical headphone amplification, and the Novo/Entheos line is a sensible no-fuss choice for driving proper headphones from RCA line-level sources. At this price, the main upside is value rather than speculation—if it powers up cleanly and the 24V supply is included, it should be an easy buy for someone who wants a compact, well-made amp without paying up into the £259 upper quartile.
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.
