Versus chasing a new desktop amp at this spend, £209 for a used Hifiman EF400 looks fair rather than flashy. It sits just above the £185 median and right on the upper side of the £155–£209 typical used band, so this is a reasonable ask if the unit is clean and fully functional.
The EF400 is well liked for its punchy, spacious presentation and straightforward all-in-one appeal, especially if you want a solid DAC/amp with Hifiman’s house tuning. At this price, value is strongest if it’s an original-owner piece with the power supply and any stock accessories included; otherwise, there’s little room to pay extra.
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.
