The next generation of xDuoo DAC/Amps

The TA-22 is a desktop DAC and balanced tube headphone amplifier that provides high performance USB, optical, coaxial, and Bluetooth 5.1 audio decoding. Combining an XMOS XU208 USB chip and dual ESS D/A chips, the TA-22 supports PCM 32-bit/384kHz and DSD256, as well as MQA rendering. Connect your laptop, phone, or tablet via Bluetooth 5.1 and enjoy audiophile-grade Bluetooth codecs, like LDAC and aptX HD.                

3000mW balanced output

Plug in your balanced headphones into the 4-pin XLR and 4.4 balanced outputs to enjoy up to 3000mW of output power. This much power can easily drive headphones with impedance from 16-600Ω. 

Bluetooth 5.1

The TA-22 supports high-end Bluetooth 5.1 codecs like LDAC, Qualcomm aptX, and aptX HD. With playback support for 24-bit tracks and transmission up to 50 feet away, it’ll help you cut cords without sacrificing quality. 

Dual ES9038Q2M DAC chips

Two ESS SABRE DAC chips process the left and right channels independently. These 32-bit audiophile-grade DAC chips decode 32-bit/384kHz PCM audio with a signal-to-noise ratio of up to 118dB. 

Tube + transistor hybrid amp structure

Using a hybrid amp structure, the TA-22 offers the best of both tube and transistor worlds. With strong output power, the transistors can drive any sort of headphone, while dual 12AU7 tube amplification provides musicality, warmth, and smoothness. 

Japanese capacitance

The TA-22 uses a series of Japanese ELNA and NICHICON capacitances, which give the TA-22 a smooth and warm presentation with transparent high frequencies.
