Professional reviewers commend the DP-UB420P for its strong 4K picture quality, compact footprint, and robust audio support, noting that its Twin HDMI and HCX processor deliver cinema-grade performance at a mid-range price. However, they criticize the omission of Dolby Vision, the lack of legacy high-resolution audio formats, and a basic remote, positioning it as a solid but not premium option.
Everyday users praise the player's crisp 4K visuals, easy setup, and convenient Wi-Fi streaming, especially valuing its small size for tight spaces. Recurring complaints focus on the missing Dolby Vision, occasional app lag, a rudimentary remote, and region-lock restrictions for international discs.
Professional reviewers consider the FiiO M23 a go-to DAP for audiophiles, emphasizing its raw power, precise measurements, and premium build. They commend its ability to drive demanding headphones with low distortion while noting the trade-off of a heavier, bulkier chassis and a customized Android UI that may feel less polished.
Everyday users overwhelmingly praise the M23's sound quality, battery endurance, and massive storage capacity, often calling it "audio perfection." The most common criticisms focus on its size and weight, the need for a protective case, and occasional heat during fast charging.
