The EF400 has a solid reputation as a capable all-in-one amp/DAC with a meaty, easygoing presentation, and at A$650 this asking price is well above the recent used market for this model. Against a typical used median of A$349 and 75th percentile of A$396, this sits firmly in ambitious territory rather than fair-value territory.
That doesn’t make it a bad unit, just a pricey one unless it’s unusually complete or freshly serviced. It’s worth buying for the balanced sound, strong headphone drive, and straightforward desktop usefulness, but I’d want exceptional condition, original packaging, and accessories at this level. Otherwise, waiting for a lower-priced example looks smarter.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Hifiman traces its origins to 2005, when Dr. Fang Bian, a chemist with a lifelong passion for audio electronics, founded Head-Direct in the United States as an online retailer and headphone developer. By 2007, he rebranded to Hifiman, relocating manufacturing and R&D to Tianjin, China, while maintaining sales operations in the US and beyond. This fusion of American entrepreneurial drive and Chinese production expertise propelled the brand from modest in-ear monitors to global prominence.
The company specializes in high-end headphones, particularly planar-magnetic and electrostatic models renowned for their detail and soundstage, alongside complementary portable digital audio players, headphone amplifiers, and cables. Early milestones like the 2009 HM-801—the first pocket-sized high-resolution player—and the HE-5 planar headphones established its innovative edge, with co-founder Binwu He pioneering planar technology integration.
Hifiman commands a elite position in the audiophile market as a high-end leader, delivering reference-grade performance that rivals legacy brands. Its products earn consistent acclaim for transparency and musicality, appealing to discerning buyers seeking uncompromising planar transduction without vintage pretensions or mid-tier compromises.
