XDUOO XA-02 MQA ES9039Q2M Balanced DAC&Headphone Amplifier

XDUOO XA-02 MQA ES9039Q2M Balanced DAC & Headphone Amplifier Overview The XDUOO XA-02 is a powerful balanced DAC and headphone amplifier designed for audiophiles. It uses the latest ES9039Q2M DAC chip, supports a wide range of audio formats, and provides high output power, making it an excellent choice for high-fidelity audio experiences. The unit is equipped with balanced output technology, a wide range of inputs, and advanced Class A amplification for superior sound quality. Features Really Balanced Output: From decoding to the amp circuit, this balanced output reduces noise and channel crosstalk, improving sound separation and reducing background noise. High Output Power: Delivers up to 910mW with a 6.35mm output and 2000mW with a 4.4mm balanced output. Supports Multiple Music Formats: Supports full MQA format (up to 8x expansion, 32bit/384kHz), DSD256, PCM 32bit/384kHz, and DXD formats. Multiple Input Interfaces: USB, coaxial, optical, and Bluetooth inputs, supporting SBC, AAC, aptX, aptX LL, aptX HD, and LDAC formats. Balanced Class A Buffer: Transistor Class A buffer design keeps the circuit in optimal condition to deliver powerful output and high load capacity. Built-in Relay Protection: Protects both headphones and the unit during power on/off to prevent popping noise. Digital Volume Adjustment: Digital volume control eliminates low-volume imbalance. The background light changes color with volume adjustment, providing visual feedback.
