Timing matters here because the HP70 is a current-generation piece, not a forgotten legacy box, so a clean used unit is mainly about condition and completeness rather than chasing an old model that’s been superseded. At £245, it sits essentially on the market median of £244, so this reads as fair rather than a bargain; it’s not cheap enough to call a standout deal, but it isn’t asking-overreach either.
That makes it a sensible buy if you want a compact, fully balanced headphone amp/preamp with real versatility and strong reputation for punchy, transparent performance. The upside is straightforward: it does double duty well, and if the unit is tidy with the PSU and original accessories, the value is solid. I’d only push for a discount if anything is missing or the seller can’t confirm proper working order, since at this price you want a clean, complete example.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Gustard is a Chinese hi-fi brand headquartered in Shenzhen, a hub for technology innovation, where it specializes in research and development of digital audio components. Emerging from Shenzhen Geshide Dianzi Electronics, the company has carved a niche without a prominent founding year or notable individual founder highlighted in public records, focusing instead on engineering-driven designs since its inception in the digital audio boom.
The brand excels in DACs (digital-to-analog converters) and headphone amplifiers, offering models like the delta-sigma X30, A26, and A18 series alongside R2R ladder designs such as the R26 and R30. These incorporate premium chips like ESS ES9039SPRO in quad-mono setups and AKM AK4499EX, supporting high-resolution audio, streaming, and clock synchronization for precise playback. While not venturing into speakers, turntables, or cables, Gustard emphasizes measurable transparency in frequency response, crosstalk, THD+N, and SNR.
Positioned as a mid-to-high-end contender, Gustard delivers rational, science-backed performance that rivals pricier competitors, appealing to discerning buyers seeking value in transparent sound. Reviews praise its spectacular results and R2R appeal for audiophiles, though some note room for pricing refinement against delta-sigma peers. It holds strong favor among enthusiasts for accessible excellence from China.
