HiFiMan EF400 Headphone Amplifier (with DAC) Great build with heavy transformer and beautiful R2R sound. In mint conditions with original packaging. Condition: As New / Mint Payment Method: Paypal, EFT, Cash on Pickup Region/State: (VIC) Victoria/Australia By DMax 6 Comments Secure Ad AUD $350 Date: October 16, 20241 yr
A$350 is right on the money for this one: it sits just under the A$355 median of recent comparables and well within the tight A$353–A$355 used band, so it reads as fair value, not a bargain or an ask that needs haggling. For a like_new unit, that’s a sensible buy if you want one now rather than waiting for a rare dip.
The EF400 is well-liked because it’s a compact all-in-one amp/DAC with plenty of drive, a clean presentation, and Hifiman’s discrete R-2R flavor that suits planars and many dynamic headphones. At this price, the upside is mostly convenience and condition: if it’s genuinely tidy and includes the original PSU/cables, it’s an easy, low-drama pickup.
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.
