The xDuoo XD05T is a compact DAC and amplifier featuring tube amplification, enabling users to experience the rich sound characteristics of vintage tube technology on the go. This model caters to audiophiles who value the intricate and warm audio signature reminiscent of 1960s tube amplifiers. It incorporates a hybrid circuit that merges the smoothness of tube sound with the strength of transistors, ensuring exceptional audio quality, even when paired with high-impedance headphones.
The XD05T features meticulously chosen miniature tubes that enhance the sound with delightful harmonics, resulting in a more vibrant and emotive listening experience. Its hybrid design combines the warm characteristics of tube sound with the robust output signal from transistors, enabling compatibility with headphones of up to 300 ohms impedance and delivering power levels of up to 556 mW.
The device features three adjustable gain levels, providing a versatile solution suitable for both sensitive in-ear headphones and high-performance full-size models. For users who prefer enhanced low frequencies, the “Bass On” function adds depth to the bass without compromising the overall sound quality.
Despite its compact design, the xDuoo XD05T can function not only as a portable device with a built-in battery but also as a stationary unit when connected to a power source. Its extensive connectivity options—including USB, Bluetooth 5.1, AUX, and balanced outputs—ensure compatibility with a wide range of modern audio sources. Additionally, the precise volume control, featuring 99 increments, allows for optimal sound levels, even with high-sensitivity headphones.
