About tube + transistor hybrid amplifier

Front tube amplifier and rear transistor combine the advantages of two amplifier circuits to achieve the ideal sound effect and make you immersed in the happy atmosphere of music.


Tube amplifier has its unique ”tube sound”, 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.
