• intros：{"brand_intro":"君子（Rega）是英国老牌Hi-Fi厂商，成立于1973年，由Tony Relph和Roy Gandy联合创立。品牌以\"音乐至上、简约设计\"为哲学，坚持英国本土研发与制造。Rega的黑胶唱机（如Planar系列）全球闻名，其唱放产品同样秉承\"少即是多\"的理念，采用最简信号路径和精选元器件。Fono MM MK5是Rega旗下最畅销的入门级唱放，被英国《What Hi-Fi?》连续多年评为\"最佳入门唱放\"。","product_intro":"Fono MM MK5定位纯MM唱头用户，是Rega唱机的最佳搭档。核心卖点：极简电路设计（仅7个元件在信号路径上），确保信号纯净；采用Rega自家设计的低噪声电源模块；声音风格中性偏暖，乐感流畅。适合搭配Rega Planar 1/2/3等唱机，或同价位其他MM唱头。相比Zen Phono，Fono MM MK5声音更\"英国声\"——柔和、耐听，但功能单一（不支持MC），且价格更高。","key_specs":{"增益":"MM: 40dB","信噪比":">85dB","输入阻抗":"MM: 47kΩ","RIAA精度":"±0.3dB（30Hz-20kHz）","尺寸":"180×150×50mm"}}
