Professional reviewers praise the DP-UB420 for its HCX processor that delivers filmmaker-intended 4K/HDR quality, precise color reproduction, and HDR10+ support. They highlight the HDR Optimizer for TV-matching brightness, twin HDMI outputs for pure-audio paths, and extensive high-resolution audio decoding as premium strengths, calling it a compact player with uncompromising picture and sound. The lack of ENERGY STAR certification and gaming features are noted as minor drawbacks.
Everyday users appreciate the reliable built-in Wi-Fi for streaming and firmware updates, the cinema-like 4K HDR playback, and the convenience of voice control. They also value the ability to attach large external hard drives for extensive media collections. No major complaints surface beyond the expected limitations of a dedicated media player.
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.
