Pro-Ject’s “Amp Box” line is a family of ultra-compact Class D power amps, but the listing doesn’t specify which model (S3, DS2, DS, etc.), so the £172 asking price is hard to benchmark against the typical used market in GBP. Without the exact model, you can’t tell if this sits below the 25th percentile (a strong deal), near the median (fair), or above the 75th percentile (ambitious).
What makes any Amp Box worthwhile is its punchy, clean sound in a tiny chassis, often paired with a dedicated linear power supply for better dynamics. If this is the Amp Box S3 (new retail ~£330–£350), £172 would be a genuine bargain on the used market; if it’s the newer DS2 (new ~£450), the price is fair. Before buying, confirm the exact model, check that the external DC power supply is included and intact, and verify the speaker terminals and RCA input show no wear. If the unit is original-owner and clean, this is a solid entry into compact hi-fi power.

Pro-Ject Audio Systems traces its roots to 1991 in Austria's Weinviertel region, north of Vienna, where founder Heinz Lichtenegger launched the brand amid the CD revolution. Kicked out of music school as a youth, Lichtenegger channeled his passion for analog sound into affordable, high-quality turntables at a time when vinyl seemed obsolete. His debut Pro-Ject 1, hand-assembled in the Czech Republic, earned rave reviews as a top high-end device, igniting a success story that relocated headquarters to Vienna before returning to Mistelbach in Lower Austria.
The brand excels in turntables, establishing itself as the world's largest and leading producer in that category, while expanding into a full spectrum of hi-fi components since 2000. Offerings include amplifiers, DACs, headphone amps, speakers, cables, and phono stages, all emphasizing essential sound reproduction with durable materials and minimalist design. Manufacturing remains European—primarily in Czechia, Slovakia, and Germany—prioritizing sustainability through local sourcing, short transport, and products built for longevity.
Pro-Ject holds a commanding niche as the go-to for mid-tier audiophiles seeking boutique European craftsmanship without extravagant pricing. Distributed in over 80 countries, it appeals to vinyl revivalists and discerning buyers who value analog purity, innovation, and value-driven performance over flashy excess, cementing its reputation as a pioneer in accessible high-fidelity.
