Class A working status is another feature of this power amplifier . Transistor amplifiers often have a blunt sound, and the Class A working state is an effective way to eliminate the stiff feeling in the sounds. Some people think that the sound of a well-designed Class A transistor amplifier can be comparable to a tube amplifier as almost as close   .


As we all known, the Class A amplifier has excellent linearity at low levels, and there is no switching "distortion"; since the transistor is always on, there is no crossover distortion. When the output power changes rapidly  (for example, during a large dynamic symphony signal swing), the current phase shift of the power supply is almost zero, so the voltage regulation rate is excellent; because there is always a consistent  current present in the circuit, it is very sensitive to sudden signals (such as piano, plucking) The instant rise and fall of music, percussion, etc.) can responded so quickly. This powerful driving capability enables the speaker to work properly and controlled . In this way, the inherent advantages of the Class A amplifier have the ability to shine , the sound is warm, sweet, and delicate. It is a model that senior-experienced  enthusiasts are diligently seeking, and even considered the highest quality musics playback  mechanism.


在元器件选用上，全平衡传输和甲类工作状态铸就了必选优质品，并且优中选优。比如前级配置两只电源变压器分别为两声道供电，动用8只各为15000μF共12万微法日本乐声电容滤波。后级专门设计了680W电源变压器，连同前级共用了日本乐声滤波电容15000μF×20=300000μF，这是在高级机中也少见的。每声道4对日本山肯管C4883、A1859推动管推动东芝4对功放管2SC5200、2SA1943

built like a tank sial!
