无论是用电子管、晶体管、场效应管或集成电路制造的放大器,其声音都各有不尽人意的缺憾。究其原因,是这些器件各有与生俱来的物理特性,有优点也有缺点。如何巧妙地利用其优点,回避或淡化其缺点,就成为设计者所追求的目的了。例如,为“中和”CD机生硬的“数码声”,近些年来纯电子管放大器卷土重来,但又带来了速度慢、信噪比低、耗能高的问题。声雅厂推出的集电子管、晶 Whether it is the use of tubes, transistors, FETs or amplifiers made of integrated circuits, the voices are all unsatisfactory shortcomings. The reason is that these devices have their own inherent physical characteristics, there are advantages and disadvantages. How clever use of its advantages, to avoid or dilute its shortcomings, it has become the designer’s goal. For example, in order to “neutralize” the hard-wearing “digital sound” of CD players, pure-tube amplifiers have come back in recent years, but with the problems of slow speed, low signal-to-noise ratio and high energy consumption. Shengya plant launched the collection of tubes, crystal
