US$145 is fair, sitting right at the top of the recent used cluster but still within the normal market for this model given a median of US$133 and a 75th percentile of US$145. It’s not a bargain, but it’s not stretched either, especially if the unit is clean and complete.
The HA-2 SE remains a well-liked portable DAC/amp because it sounds polished, is genuinely pocketable, and still does a nice job driving a wide range of headphones with a proper analog-in option and battery power. At this price, the upside is in condition and accessories: original cable, case, and a healthy battery matter more than usual on an older portable unit.
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.
