Tube charm + transistor oomph = aw yeah
Meet the xDuoo MH-02. This DAC/Amp merges old-school tube charm with modern digital muscle, giving you the best of both worlds. With the soulful warmth of tube amplification and the crisp, detailed transients of a Class-A transistor buffer, this hybrid amp delivers music the way it’s meant to be heard—warm, rich mids combined with treble that sparkles with detail.
USB DAC decoding: high-res heaven
Plug in the MH-02 and get ready for an earful (in a good way). This little dude decodes high-res audio up to PCM 32-bit/384kHz, DSD256, and MQA 32-bit/384kHz from any device you’ve got lying around. Thanks to the CS43131 DAC chip, you get crystal-clear decoding.
Hybrid moments: tubes meet transistors
All hail the hybrid amp. The MH-02’s double 6J1 tubes give you that smooth, warm sound that makes everything feel like a lazy Sunday morning. The transistors, on the other hand, bring the muscle, with a Class-A buffer that delivers both low-end oomph and high-end sparkle. It’s like putting a rocket engine in your grandma’s Buick.
Strong output power that drives anything
With 1300mW of output power, the MH-02 isn’t messing around. High-impedance, low-impedance—doesn’t matter. This thing can drive whatever headphone you’ve got.
Gain switch: dial it in
Got finicky headphones? No worries. The MH-02 has a gain switch that lets you tweak the output to match your headphones’ impedance. High gain, low gain—just flip the switch and you’re set.
Line out: ready for anything
Need a pre-amp for your gear? The MH-02 has a line out that runs through the tube stage and is controlled by the volume knob. Hook it up to your amps or active speakers and hear your sound quality jump up a notch.
Protect those ears
No one enjoys a loud POP when they turn on their gear. The MH-02’s built-in relay mute circuit ensures you won’t have to deal with that nonsense. It keeps your tubes happy and your ears unscathed. Easy, breezy, and totally hassle-free.
Looks that kill
Wrapped in a sleek, sandblasted, textured shell, the MH-02 isn't just about great sound—it looks fantastic too. Simple, clean, and ready to blend into any setup without shouting for attention.
