TA-22 is a desktop DAC & tube balanced headphone amplifier which contains high performance USB, optical, coaxial and Bluetooth audio decoding and tube for audio processing. The USB audio decoder using the XMOS's XU208 chip, support up to PCM 32bit/384kHz and DSD256, and supports MQA render decoding.The Bluetooth adopts Qualcomm chip, supports atpX, atpX_LL, atpX_HD and LDAC HD format. The DAC chips are used two ES9038Q2M chip from ESS, which has lower distortion and higher SNR. Adopts 12AU7 tube for pre- amp for soften the sound, the post-amp is adopted transistors for class A buffer, built-in +/-16V for OCL circuit, so that it has not only soft nature sound but also not lose speed.
This product is suitable for connecting with different audio source, such as PC, mobile phone, and other types of playback equipment. It can improve the sound quality of the original playback equipment effectively, and it also can drive a variety of high-end headphones, so that you can enjoy more real, more shocking music!
