Against your £161 median and £141/£171 quartiles, £188 sits above the 75th percentile, so this reads as ambitious rather than fair-value. It is not wildly off, but it is clearly asking a premium over the current used market and would need something more than average to justify it.
That said, the RU7 is a well-liked dongle DAC/amp for its compact size, lively presentation, and strong desktop-or-travel usefulness, so a clean example can still make sense if it comes with the right accessories and looks lightly used. At £188, I’d want confidence in condition, completeness, and provenance; otherwise, I’d keep hunting unless the seller can show a genuinely tidy, near-new unit.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

From the outset, the company focused on crafting audiophile-grade components under the Cayin brand, blending Eastern precision with a passion for musical fidelity. Over three decades, it has evolved from traditional hi-fi roots into a multifaceted player, emphasizing equipment that delivers exceptional sound across diverse price points to democratize high-quality audio.

Its portfolio extends to CD players, speakers, digital audio players (DAPs), desktop systems like the i-series, portable amplifiers, in-ear monitors, and even innovative DACs such as the compact RU2 dongle.
