• intros：{"brand_intro":"乂度成立于2015年，是中国专注于电子管（胆机）耳放设计的品牌，以\"温暖模拟声\"为特色。创始人张磊是电子管放大器资深工程师，曾为多家国际品牌代工胆机。乂度坚持手工焊接和元件配对，每台设备经过48小时老化测试。TA-30是其经典入门级胆机，采用俄罗斯Electro-Harmonix 12AU7电子管，提供可更换运放设计，深受\"胆机入门\"用户喜爱。","product_intro":"TA-30定位入门级电子管耳放，核心卖点是\"胆石混合\"架构（前级电子管+后级晶体管），兼顾电子管的温暖音色和晶体管的驱动力。输出功率1.2W@32Ω，适合驱动HD600、DT880等中高阻抗耳机。相比同价位石机（如飞傲K5 Pro），TA-30声音更柔顺、人声更有韵味，但解析力和瞬态稍弱。支持RCA输入和6.35mm输出，无平衡接口，适合听流行、爵士的玩家。","key_specs":{"电子管型号":"俄罗斯12AU7（可更换），前级放大","输出功率":"1.2W@32Ω，0.6W@300Ω","失真率":"THD+N <0.1%（电子管典型值）","接口配置":"6.35mm耳机口、RCA输入、RCA输出（前级模式）","电源设计":"外置12V DC适配器，内置高压升压电路"}}
