Adopt double 6JI tube for pre-amp, making voice sweet and exquisite
Making the sounds thorough and sweet
Adopt transistors for class A buffer, so it can easily drive any kind of earphones with strong load capacity.
Built-in mute circuit when turn on amplifier to avoid POP noise and make sure the tube is worked at its best condition.
Built-in overvoltage/overcurrent protection, so that it can be prevented damage to the amplifier if the input voltage/current exceeds the limit value.
About tube + transistor amplifier Tube amplifier has its unique "smell of tube", sweet, soft, warm and listenable voice and good musicality and atmosphere; but its high- frequency transient response and resolving power are worse than that of transistor especially when listening to symphony. "Transistor" has the advantages of large dynamics, high speed, strong resolving power and strong driving force, especially suitable for the songs with large dynamics; but it is not soft enough and its high-frequency sound is sharp and dry. Therefore, front tube amplifier and rear transistor combine the advantages of two amplifier circuits to achieve the idea sound effect and make you immersed in the happy atmosphere of music.
