xDuoo Amplifiers Editorial Review
The XDUOO MT-604 6J1 Balanced Tube Pre-amp XLR4.4MM Balanced InputOutput Class-A Hybrid Amplifier has received mixed reviews, some customers claim that it is a "piece of garbage" while others are "satisfied". The device does not have a USB input and requires a DAC with balanced output to connect to a laptop. Additionally, the amplifier has a 3 pin "balanced connector" as an input, meaning XLR cables will need to be used. The item does not come with any audio cables, but it does include a power adapter. The amp is recommended for use with speakers that support balanced input, and it can be used as a preamp with a passive volume knob in the middle. Swapping tubes is easy with the device, and the sound quality has been described as "outstandingly clear and warm". The two volume controls are useful, but the knobs need to be easier to see and set both to the correct level.
