Condition is unknown, and at US$999 this is plainly above the recent used market here: the median is US$609, with the 25th percentile at US$414 and the 75th at US$804. That makes this an ambitious ask rather than a fair buy, unless the unit is unusually complete, freshly serviced, or bundled with box/accessories that matter to you.
The X20 Pro is well liked for its hefty build, dual-mono design, and still-respectable sound, so a clean example can be worth owning. But at this price I’d want proof it’s in excellent working order, with the remote, original packaging, and no input or display issues; otherwise the premium is hard to justify versus the stronger deals that show up lower down the range.
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.
