xDuoo MT-604

xDuoo MT-604
The xDuoo MT-604 headphone amplifier combines the characteristic sound of tubes with the power of a Class-A transistor amplifier, offering a detailed, dynamic, and musical listening experience. Its hybrid design and high power output make it suitable for a wide range of headphones, including high-impedance models. Furthermore, its compact metal body makes it easy to integrate into both a home hi-fi system and a professional audio setup. The xDuoo MT-604 uses four 6J1 tubes in the pre-amp stage, which give the sound a smoother, warmer, and more natural character. The Class-A transistor buffer ensures high dynamics, more precise sound control, and a power output of up to 2000mW. Symmetrical XLR and 4.4mm balanced inputs and outputs help to minimise noise and improve channel separation when listening to high-quality music.

Tube sound character and high power
The xDuoo MT-604 combines the musical expression of tubes with the power of modern transistor amplification. The 6J1 tubes create a smoother, more natural rendition of music with a pleasant atmosphere, while the Class-A transistor buffer adds fast response, high dynamics, and plenty of power for more demanding headphones. The balanced design with XLR and 4.4mm connectors helps to reduce interference and improves the spatial rendering of the sound. The amplifier supports headphones with an impedance from 16 to 600 Ohm and offers independent volume control for the left and right channels for a more precise stereo image.
