Our take
A high-performance headphone amplifier from xDuoo, the TA-05 is designed to give you the warm-sounding experience of a tube amp on a budget. It’s built with two preinstalled 69I tubes, which can easily be swapped out for tubes of your choice if you’d like to experiment with the sound signature. The TA-05 can drive demanding headphones with ease, adopting transistors for a Class-A buffer and outputting 780 mW at 32 ohms. It also features built-in over-voltage and over-current protection to prevent damage to the unit should the input voltage or current exceed the limit value.

Double 6JI tube for pre-amp, reproduces sweet highs/treble
Adopt transistors for class A buffer, so it can easily drive most headphones with strong load capacity.
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 ideal sound effect and immerse you in the happy atmosphere of music.
Making the sounds thorough and sweet
Adopt Japanese Nichicon capacitance specifically for audio enthusiasts, making sound thorough and sweet.
Built-in overvoltage
It built-in overvoltage/overcurrent protection, so that it can be prevented damage to the amplifier if the input voltage/current exceeds the limit value.
Built-in mute circuit
It built-in mute circuit when turn on amplifier to avoid POP noise and make sure the tube is worked at its best condition.
