Compared with the obvious alternative at this money, this is expensive: the asking price of £799 sits well above the recent comparable median of £312 and even clears the 75th percentile at £657, so it’s firmly in ambitious territory. For a buyer, that means you should only lean in if this specific example is unusually strong in condition, provenance, or completeness; otherwise it’s priced like a premium outlier rather than a normal used buy.
That said, this is a respected integrated amp from a brand with a good reputation for musical, full-bodied sound and solid build, so the appeal is real if you want a distinctive piece rather than a generic box-ticker. If it’s truly clean, original, and freshly serviced, the upside is in owning a less-common model that can be a rewarding long-term keeper; just make sure the controls, inputs, and channel balance are all behaving properly before paying top-end money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
ONIX emerged from the creative seaside town of Brighton, UK, in the late 1970s and early 1980s, when engineer Tony Brady—initially experimenting with compact power amplifiers in a warehouse near Brighton Pier—teamed up with Michael O’Brien of Rogers and later Adam Worsfold. Their first classics, the OA20 and OA21 integrated amplifiers, launched in 1981, establishing the brand's signature black-gold aesthetic and driving it into over 30 international markets by the early 1990s. Facing intensifying competition, the core technology and brand were acquired in 1997 by Taiwan's Sound Art Co. under Mr. Pu Hsao Hsiung, marking a shift toward Asian manufacturing expertise.
The brand's product focus has centered on high-performance electronics, particularly integrated amplifiers like the enduring OA21 series, alongside CD players, DACs, and SACD transports such as the recent Zenith XDA20 and XST20. Recent revivals, including the 2023 Miracle High-End Hi-Fi stack unveiled at Munich, blend ONIX's analog tuning heritage with modern streaming and digital capabilities, often produced in partnership with Shanling.
Note that ONIX's history involves trademark disputes, with competing claims between a UK entity led by Adam Worsfold and the Shanling-affiliated version; buyers should verify current ownership. Positioned as a niche high-end player, ONIX appeals to enthusiasts seeking British-inspired sound—transparent, dynamic, and faithful—with measured specs like sub-0.002% THD underscoring its rational, performance-driven ethos rather than flashy exotica.
