Fully-balanced, top-tier sound at an affordable price
For just $200, the xDuoo XA-02 offers unbelievable value, combining features you'd expect from much pricier gear. This fully-balanced DAC/Amp delivers 2000mW of power, a top-of-the-line ESS DAC chip, a Class-A buffer, and full MQA support. Compact yet packed with high-end components, the XA-02 is your key to precise yet natural sound, whether you're listening through headphones or using it as a preamp for powered speakers.
Fully-balanced output
Sayonara, crosstalk and noise. The XA-02's balanced design extends from the decoding stage all the way through the amp circuit. By keeping the signal paths separate, it majorly reduces interference caused by ground loops and channel crosstalk, leaving you with clear, isolated sound.
Power for every headphone
Whether you’re driving sensitive IEMs or high-impedance headphones, the XA-02 has you covered. It features 910mW output through the 6.35mm jack and an impressive 2000mW through the 4.4mm balanced output.
All your favorite formats
With support for full MQA, DSD256, PCM, and DXD, the XA-02 gives you access to the highest-resolution audio available. Whether you're streaming, downloading, or using a Hi-Fi player, this DAC/Amp has the flexibility you need.
Super low distortion
Distortion? Not here. With a THD+N of just 0.0005% and a signal-to-noise ratio of 121dB, you’re going to have a hard time hearing anything other than the music.
Connect anything
USB, coaxial, optical, Bluetooth—whatever you’re using, the XA-02 is ready for it. Bluetooth support includes all the popular codecs like aptX, LDAC, and AAC, so you don’t have to sacrifice quality for convenience.
Class-A buffer for powerful output
By using transistors in a Class A buffer, the XA-02 ensures that the circuit stays in its optimal operating range. This not only maximizes performance but also allows the amp to handle a wide range of headphone loads with ease, giving you powerful, consistent sound.
Built for audiophiles
The XA-02 features the latest ESS ES9039Q2M DAC chip, known for its accuracy and musicality. Along with imported high-end capacitors and professional power management chips, this DAC/Amp is designed to deliver sound with smooth highs, rich mids, and warm lows. You'll hear every detail.
Protect those ears
Pop noise when you power up your gear? Not with the XA-02. The built-in relay protection ensures that your headphones and equipment stay safe, eliminating the jarring pops you might hear when turning your amp on or off.
Digital volume with a twist
The XA-02's digital volume control ensures perfect channel balance, even at low volumes. Plus, the sleek background light changes color as you adjust the volume, giving you a quick, visual indication of where your levels are at.
Compact and stylish
The XA-02 packs serious power into a small footprint. At just 0.9kg (2 lbs), it’s easy to place on your desktop without taking up too much space. Its sleek, space gray design ensures it blends right in with your setup.
