Against your own comp set, US$115 sits just above the US$113 median and comfortably within the middle of the pack, so this reads as fair pricing rather than a steal or an ambitious ask. It’s also well below the US$188 75th percentile, which keeps it on the buyer-friendly side of the market.
The HA-2 is a well-liked portable DAC/amp for its clean sound, solid power for a slim unit, and genuinely useful versatility with digital and analog sources. If it’s complete and healthy, the upside is convenience: a compact all-in-one that still has a strong reputation among used-audio buyers, so I’d treat this as a sensible pickup at this price.
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.
