Oppo HA-1 Headphone Amplifier (with DAC) Excellent as new condition. Postage available. Info here: https://www.oppodigital.com/headphone-amplifier-ha-1/ Condition: As New / Mint Payment Method: Cash, Bank Transfer Region/State: (VIC) Victoria/Australia By Mick64 0 Comments AUD $850 Date: January 18, 20251 yr
This is a well-regarded all-in-one analog/digital preamp and headphone amp, and A$850 sits a touch above the A$791 median but still inside the normal used spread versus the A$896 75th percentile. In other words, it reads as fair rather than cheap or ambitious, especially if the unit is clean and fully functional.
The HA-1 is respected for its solid build, balanced connectivity, and genuinely capable headphone stage, so it’s a practical buy for someone wanting a serious control center as well as a strong amp. If it’s complete with remote and original accessories, that helps justify the ask; at this price, I’d mainly want confirmation that inputs, volume control, display, and headphone outputs are behaving properly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Oppo Digital, the audiophile arm of the Chinese electronics giant Oppo, traces its roots to 2004 with the establishment of its U.S. division in Menlo Park, California. This overseas outpost of the Dongguan-based parent company, founded amid BBK Electronics' expansion under entrepreneur Duan Yongping, focused on high-fidelity audio and video gear sold exclusively online. From humble beginnings in MP3 players and DVD units, it carved a niche in premium home entertainment during the Blu-ray era.
The brand specialized in personal audio and video equipment, gaining acclaim for Blu-ray Disc players renowned for superior sound quality, sleek design, and robust performance. Entering the personal audio market in 2014, Oppo offered headphones and related products that emphasized precision playback, though it never delved deeply into traditional hi-fi categories like amplifiers, speakers, turntables, DACs, or cables.
Oppo Digital held a strong mid-to-high-end position among discerning buyers, prized for reliable, value-driven excellence in digital playback before ceasing operations around 2020. Its legacy endures as a benchmark for accessible audiophile gear, appealing to enthusiasts seeking polished integration of video and sound without boutique excess.
