Tube + Transistor Hybrid Amplifier

MT-604 adopts four 6J1 tubes for pre-amp and transistors for class A buffer. The 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.

Compact Portable Headphone Amplifier

As it adopts transistors for class A buffer, with strong output power up to 1300mW, it can easily drive many kinds of headphones. Moreover, designed with palm-size (17*10*6cm), it’s easy to carry everywhere for a real-time HiFi music experience .

Professional Capacitance

Apart from adopting the special enthusiast Japanese Rubycon capacitance as the coupling capacitance to present a transparent and sweet sound, it also adopts the special enthusiast Japanese Nichicon capacitance as the main filter capacitance to reach smooth and warm sound, and splendid high frequency.

XLR and 4.4mm Balanced Input/Output& Independent Volume Adjustment

MT-604 has XLR and 4.4mm balanced input, rich and diverse interfaces, suitable for many kinds of balanced headphones. This unit is designed to adjust the volume of the left and right channels separately to reject the sound best problem.

Built-in Mute Circuit&Sand-Blast Textured Surface

MT-604 owns the built-in relay for mute circuit when turn on amplifier to avoid POP noise, besides, following the modern minimalism design, it’s crafted with sand-blast textured panel and hard aluminum alloy shell that can also resist external interference effectively, which can make sure the tube to work at its best condition. You will truly explore the beauty of it when you hold it and enjoy HiFi 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.

- 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
