HiFiMan EF600 Headphone Amplifier (with DAC) I sold my K7 and K11 R2R combo and purchased the EF600. It is the best part's of R2R and the best parts of DS in one really nice device. Its also so powerful that on low I'm using 5% of the volume pot and I really like my headphones so one of them has to go. Condition: As New / Mint Payment Method: Paypal, EFT/ PayID, Cash on pickup.

Should you jump on A$700 for this? For an EF600 in like-new condition, that’s fair-to-good value in the current used market: new pricing sits around A$1,050–A$1,120 in AU retail, while a recent like-new private sale landed at roughly A$1,260, so A$700 is comfortably below that and looks like a solid buy rather than an ambitious ask.
The reason people keep coming back to this unit is simple: it’s a strong all-in-one with HIFIMAN’s R2R-style DAC presentation, plenty of drive for demanding headphones, balanced I/O, and useful extras like Bluetooth and dual USB inputs. If the listing includes the original power cord and box, that’s an easy win; in like-new condition, this is the sort of desktop stack-killer that’s worth moving quickly on if it suits your setup.

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.
