xDuoo XD-05T / XD05T / XD 05T Portable Bluetooth Tube DAC Amplifier

Classic Sound with Carefully Selected Vintage Tubes

Tubes still hold a special place in audio amplifiers, and the XD05T takes full advantage of that with two miniature tubes from the 1960s. These carefully selected, meticulously paired vintage tubes add a touch of even-order harmonics, delivering a soft, warm sound full of emotional depth.

Hybrid Circuit

xDuoo recognizes the crucial role of the preamplifier in shaping overall sound quality. To highlight the distinctive "tube sound," xDuoo integrates a vacuum tube into the preamplifier stage. For enhanced driving power, transistors are employed in the current amplification stage, delivering robust output. When driving 300-ohm headphones, the power reaches up to 556mW!

Rich and Practical Adjustment Functions

The XD05T offers three gain levels to adapt to a variety of headphones. The TURBO (L) setting is ideal for IEMs, TURBO (M) suits low-impedance headphones, and TURBO (H) is tailored for high-impedance headphones. This versatility ensures users can enjoy rich, optimized sound quality across different devices.

Desktop + Portable – Two Working Modes

The XD05T offers dual power options—battery and DC—allowing for both portable and desktop use. When you need desktop-level performance, simply connect a professional Hi-Fi power supply to switch to desktop mode, unlocking enhanced capabilities.

Note: The DC power supply is sold separately. Also, as the device generates heat during operation, avoid placing it in a bag or confined space while in use.
