Objective, source-traceable evaluation of HiFi gear. Transducers (IEM / headphone / TWS): 量感 (per-band quantity) + 风格 (signature) from frequency-response-vs-target; technicalities from review consensus. Source gear (DAC / amp / DAP): measured competence (SINAD/THD/output-Z/power) + system matching + chip/topology — a competent source is audibly transparent. Searches all sources (measurements, media reviews, specs) via a style-profiled media roster (orientation judged dynamically), cleans them, renders a bilingual verdict where every claim traces to evidence. Triggers: "客观评价这条耳机", "对比 A 和 B 的声音", "这个 DAC 素质如何 / 推得动吗", "$hifi-review". Not for: buying/价格 recommendations; EQ tuning; speakers; non-audio.
