xDuoo - MT-604

The xDuoo MT604 houses a combination of front tube amplifiers and rear transistors. Adopt four 6J1 tubes for the pre-amp and adopt transistors for class A buffer. This combination of a front tube amplifier and rear transistor combined gives the device the advantage of two amplifier circuits that achieves a full sound.

Tube Amplifiers have a unique “tube sound”, which is generally described as sweet, soft, warm and listenable but the high frequency transient response isn’t shiny. To tackle this issue “Transistors” are added into the signal path giving the sound a larger dynamic range and a sheen on the top end. The combination of this makes vocals sound sweet and exquisite while giving the MT604 the capability to output strong power that can easily drive various kinds of headphones.

xDuoo MT604 includes the special enthusiast Japanese Rubycon Capacitance as this coupling capacitance has a transparent and sweet sound. Paired with this is also the Nichicon capacitance as the main filter capacitance which outputs a smooth and warm sound with open high frequency.

xDuoo MT604 has a built-in relay for muting the circuit when it is turned on to avoid POP noise and to also ensure that the tube is working at its optimum condition. xDuoo MT604 also offers XLR and 4.4mm Balanced input, 4-pin XLR and 4.4mm balanced output. This makes the device suitable for many kinds of balanced headphones.

The panel for the MT604 is designed to give you the freedom to adjust the volume of the left and right channels separately to reject the sound-bias problem. The exterior panel for the device has a beautiful sandblast textured panel encased in a hard aluminium shell. This is an engineering feat as the panel and shell are slap-up and can resist external interference efficiently.
