xDuoo DT-01 HiFi Phone DAC Preamplifier — USB to Coaxial/Optical/Analog, PCM 32Bit/384kHz, DSD256, 350mW

Turn your phone or tablet into a high-quality digital source with the xDuoo DT-01. It accepts USB audio from mobile devices and outputs coaxial, optical or analog signals so you can feed high-end decoders, amplifiers or active speakers. Native support includes PCM 32Bit/384kHz and DSD256. Coaxial and optical outputs are supported up to PCM 24bit/192kHz and DSD64 (DoP), making it easy to integrate with a variety of external decoding equipment. The DT-01 provides its own USB power, so the audio stream comes from your phone while the unit supplies power — preserving your phone’s battery. A dedicated charging switch lets you choose whether to charge the phone while the DT-01 is in use or turned off. For private listening, the built-in headphone output delivers up to 350mW, capable of driving many headphone types so you can enjoy music without disturbing others. The DT-01 can also act as a preamplifier: the Aux output level is adjustable via the front-panel volume knob for direct control without changing the speaker volume. Color LED indicators show the playback sampling rate in real time: blue indicates 44.1-48kHz, purple indicates 96K-384kHz, and white indicates DSD64-256. If you prefer to bypass the onboard DAC, the USB output can be used to send the digital signal directly to another DAC.
