xDuoo XD-05T Portable High-Fidelity DAC & Tube Balanced Headphone Amplifier Electronic Tube BT

Overview: XD05T is a portable high-fidelity DAC & Tube balanced headphone amplifier, which integrates USB, coaxial, optical, BT decoding, and tube amplifier. The DAC chip uses two high-specification ES9039Q2M chips, which have extremely low noise and higher resolution, which greatly improves the quality of sound. It uses precision digital volume chips and two microtubes to amplify the audio to make the sound sweet and delicate. Its output power up to 1500mW per channel, can easily drive most IEM and headphones on the market. In terms of adjustable settings, in addition to driving power, bass, filter adjustment, etc., the power supply can be selected from DC power or battery-powered mode.

Features: Advanced USB Chip: The USB receiving chip, XMOS"s XU316, operates in asynchronous transmission mode, supporting up to PCM 32 Bit/768 kHz, MQA, and DSD512. It supports decoding USB audio from iOS, and Android phones, or tablets. Rich Interfaces: A rich array of input and output interfaces accommodates a wide range of usage scenarios. Coaxial and optical inputs support up to PCM 24 Bit/192 kHz and DSD64 (DOP). USB supports up to PCM 32Bit/768kHz, MQA and DSD512. The BT chip supports BT 5.1, along with APTX, APTX_LL, APTX HD, and LDAC formats. Premium DAC Chips: The DAC chip, featuring two ESS ES9039Q2M, offers superior decoding performance, extremely low noise, and higher resolution, significantly enhancing audio quality. Micro Tubes for Audio: Two micro tubes are utilized to amplify the audio, delivering a sweet and delicate sound that remains pleasant even after extended listening periods. Powerful Output Circuit: The output BUF circuit employs a rail-to-rail, low distortion, high current chip, ensuring it can drive most IEMs and headphones on the market with ease. Low-Noise Oscillators: Equipped with dual active low-phase noise crystal oscillators, and FPGA-based data shaping processing, it achieves a unified clock and minimizes jitter. Adaptable Sound Enhancement: External Turbo and Bass Features cater to a variety of headphones, allowing for personalized sound customization. Flexible Power Options: With an external power input and a power selector, it can transition to desktop mode with a switch, offering a more powerful and adaptable listening experience.
