Compared with a modern budget DAC, this is a very strong buy if you want a heavy, full-featured desktop unit rather than a lightweight current model. The used market has shown this piece landing anywhere from about US$520 to US$770 in private listings, with one broader forum mention around US$1,500 for a bundled setup, so US$219 is well below the usual standalone range and looks like a bargain.
That price makes sense because the X20 Pro is still well liked for its solid build, dual ES9028 Pro architecture, and a presentation many owners describe as detailed yet smooth rather than edgy. It also has unusually broad digital input support, so it can serve a flexible system well. At this price, the main thing to check is simple completeness and function: remote, power cord, and every input working cleanly matter more than chasing cosmetic perfection.
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.
