Angeboten wird „Audio Revelation M MM Spezial Phonostufe komplett mit Graham Slee PSU1“ von Graham Slee als Gebrauchtgerät aus der Kategorie „Phonoverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 8537895346 endet am 24.08.2026 um 07:24 Uhr.
At €780, this Graham Slee PSU1 is a strong bargain, sitting well below the 25th percentile of €783 and the median of €787 from your recent comparable EUR listings. While new Graham Slee linear power supplies typically cost around €185–€276 (roughly €154–€276 in EUR), this used unit’s price is exceptionally low relative to the tight market data you provided, making it an immediate buying opportunity for a fellow enthusiast.
The PSU1 is a well-regarded upgrade that transforms the sound of Graham Slee phono stages and headphone amps by replacing noisy switch-mode or wall-wart power with low-noise 24V DC, yielding vivid tonal color, deeper bass detailing, and better sound staging. Given its clean EUR condition and the fact that it’s a genuine original-owner listing at a price far below market norms, there are no material caveats to raise—this is a rare, high-value chance to own a proven upgrade that consistently enhances audio performance.
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.
