At US$199, this Hifiman EF400 is a clear bargain compared to the obvious alternative of paying near the US$246 median for used units, sitting well below the 25th percentile of US$204. This listing represents a strong deal for a desktop DAC/amp that delivers genuine R2R performance, making it an excellent buying opportunity rather than a risky pick.
The EF400 earns its reputation for bringing Himalaya R2R DAC architecture to an accessible price point, offering rich, natural sound with deep bass and smooth treble that rivals much more expensive gear. It handles both single-ended and balanced headphones with ample power (up to 4400mW per channel) and supports high-resolution PCM up to 24bit/768kHz. With original accessories likely included and the unit coming from an unknown but presumably original owner, you’re getting a well-loved, high-spec amplifier at a price that’s hard to justify ignoring.
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.
