笔者曾购得一台奇声388D型前后级五声道功率放大器,外表美观大方,内部工艺严谨。经过几个月的煲机试听,总体感觉:该机音质为中性偏暖,平衡度较好,中音表现较出色,不足之处是在播放大动态交响乐时总感觉低音力不从心,魄力不够;播放一些音调较高的曲子如宋祖英的《好日子》时,感到高音有些发毛,低音尚可。分析厂家提供的电路原理图,觉得该机的线路设计虽不错,但仍有不 I had bought a strange sound before and after the 388D five-channel power amplifier, elegant appearance, the internal process rigorous. After months of trial in the burning machine, the overall feeling: The machine is neutral sound warm, good balance, the tenor performance is better, the downside is that when playing large dynamic symphony always feel bored, lack of courage; Play some of the higher pitch song such as Song Zuying’s “good day”, feel some high-pitched hair, bass acceptable. Analysis of the circuit diagram provided by the manufacturer, I think the line design is good, but there are still
