Portable. Tube. DAC/Amp. 

Experience the rich, analog sound of vintage tube amplification wherever life takes you with the xDuoo XD05T Portable DAC/Amp. Ideal for audiophiles who refuse to compromise on sound quality, this portable device lets you enjoy the warmth of genuine 1960s vacuum tubes on the go. Whether you're commuting, traveling, or simply unwinding at a café, the XD05T brings your music to life with its hybrid circuit design and support for today's high-resolution audio formats. 

This is your grandfather's portable

Experience music the way it was meant to be heard—with the gentle warmth and emotion that only vacuum tubes can provide. The XD05T uses carefully selected miniature tubes from the 1960s that  generate even-order harmonics that make your audio come to life.

Hybrid circuitry for power and precision

Combining the best of both worlds, the XD05T's hybrid circuit merges the rich tonality of tubes with the robust output of transistors. This design ensures strong driving power—up to 556mW at 300Ω—so you can enjoy your high-impedance headphones without compromise.

Adjustable gain paves the way for your entire collection

Whether you're using sensitive in-ear monitors or demanding over-ear headphones, the XD05T has you covered with three gain settings. Easily adapt the output to match your headphones and enjoy optimal sound quality.

Boost the bass when you need it

Need a little extra low-end punch? Engage the “Bass On” feature to enhance the heavy bass frequencies, adding depth and impact to your favorite tracks without overwhelming the mix.

Portable design with desktop capability

Take your music anywhere with the XD05T's internal battery power, or connect it to a DC power supply for enhanced performance in desktop mode. 

Versatile connectivity options

With multiple input and output interfaces—USB, Bluetooth 5.1, AUX, and balanced connections—the XD05T seamlessly integrates with your phone, PC, tablet, or audio player. Eight usage modes ensure compatibility with a wide range of devices.

Precise volume control

Fine-tune your listening levels with 99 steps of volume adjustment. The digital volume chip allows for precise control, so you can set the perfect loudness without worrying about sudden jumps in volume—even with sensitive IEMs.
