REALLY BALANCED OUTPUT: Really Balanced output from decoding to amp circuit, reduce noise caused by ground wires and channel crosstalk, greatly improve separation and reduce background noise 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 SUPPORTS MANY MUSIC FORMATS: Support full MQA format, maximum support 8 times expansion,that is 32bit/384khz. DSD format, maximum support DSD256. PCM formats,maximum support 32bit/384khz. DXD formats,maximum support 32bit/384khz SUPER LOW DISTORTION: The THD+N up to 0.0005%, The crosstalk up to 118 dB, The S/N up to 121dB,makes you barely hear background noise 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 BALANCED CLASS A BUFFER: Use transistors as a Class A buffer to keep the circuit in the best working condition all the time, Powerful output, strong load capacity, specially designed to drive various headphones 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 BULT-IN RELAY PROTECION: Built in relay protection to avoid the POP noise when turn it on and protect the earphone and machine under abnormal conditions DIGITAL VOLUME ADJUSTMENT: Use digital volume adjustment to eliminate the problem of low volume imbalance. The charming background light will change color with the volume. You can observe the volume in time before connecting the headphones XA-02 is a high-fdelity small desktop balanced headphone amplifer that integrates USB, optical, coaxial, Bluetooth audio decoding and analog audio in, and it has an OLED 1.3 inch screen that can intuitively display various working status; USB audio decoder used XMOS’s XU316, which can suppor up to digital audio signal PCM 32bit/384KHz, MQA and DSD256. Optical and coaxial in suppor maximum PCM 24bit/192KHz, DSD64 (DOP). Bluetooth uses QCC5125, which suppor high-defnition formats such as aptX, aptX_HD, and LDAC. The analog amplifcation par adopts a fully balanced small class A design structure that can bring delicate and soft vocals without losing the explosive power and sense of speed of the music, and is equipped with +/-12V power supply as a power amplifer, with strong load capacity, it can easily drive many kind headphones, and greatly enhance the dynamics of the sound feld, which can restore the sense of reality of the concer.
