The Xduoo XD05T Portable DAC Headphone Amplifier is a high-performance device where cutting-edge technology meets vintage. Its amplification circuit is based on tubes machined in the '60s, coupled with transistors, while the analog digital conversion stage is based on two ES9039Q2M DAC chips, an XMOS XU316 USB interface and an FPGA. This little jewel of hybrid technology is therefore able to drive headphones with impedances from 32Ω to 300Ω without difficulty, while offering a soft, warm texture. In addition, it supports high-resolution sampling rates up to PCM 32Bit 768kHz, DSD512 and MQA x8 via its USB-C input. More generally, there's a full range of connectors, including an optical/SPDIF mini Toslink input, a 3.5mm jack auxiliary input/output, a balanced 4.4mm jack input/output and, of course, two 6.35mm jack and balanced 4.4mm jack headphone outputs. Added to this are various operating modes for use as a desktop DAC/Headphone amplifier, and Bluetooth 5.1 functionality thanks to a QCC5125 chip for pleasing versatility. In terms of appearance, Xduoo has chosen a green shell and gold details to highlight the vintage spirit of its device.
Xduoo has opted for authenticity by integrating tubes from a sixties production, offering a sound texture full of emotion, soft and warm, that will delight the most nostalgic. The use of these tubes also offers a wider dynamic range, greater than or equal to 116dB for the balanced 4.4mm jack headphone output and 114dB for the 6.35mm jack headphone output. The final sound reproduction is therefore rich in detail, immersive and brings a natural tone to the vocals present on every musical source.
The Xduoo XD05T's amplification stage couples tubes to a pair of transistors, providing the signal power needed to drive a wide range of headphones and IEMs. Indeed, on its balanced 4.4mm headphone output, the Xduoo XD05T is capable of delivering up to 1500mW @ 32 ohm and 565mW @ 300 ohm. As for the digital-to-analog conversion stage, it relies mainly on two ES9039Q2M DAC chips and an XMOS XU316 USB interface, enabling it to support high-resolution sampling rates up to PCM 32bit 768kHz and DSD512 via its USB-C input.
The Xduoo XD05T benefits from 3 gain settings, Turbo (L) perfect for IEMs, Turbo (M) for low-impedance headphones and Turbo (H) for high-impedance headphones. This enables it to adapt to a wide range of hardware configurations, and to deliver its best performance in all circumstances.
The Xduoo XD05T features a bass boost switch for users who want a more immersive experience. It can also be useful depending on the source used.
If you want to use the Xduoo XD05T in desktop mode, simply power it via its DC USB-C power port. Of course, it can also be used on the move, thanks to its internal 6000mAh battery, which provides excellent autonomy.
On one side of the Xduoo XD05T, there's a potentiometer for adjusting the output volume over 99 levels, for precise setting whether low or high volume is required.
