The Douk Audio U10 Mini Tube Headphone Amplifier comes equipped with a pair of upgraded GE5654 vacuum tubes, delivering a superior sound experience. All original accessories are included, ensuring a complete package.

Engineered for seamless compatibility and versatility, the U10 can effortlessly connect to a wide range of audio sources, such as MP3 players, smartphones, computers, and CD players. Its dual headphone jacks (3.5/6.35mm) are designed to provide up to 1100mW of power, enabling it to drive headphones with impedance ranging from 18 to 600Ω. Furthermore, the U10 can function as a stereo preamp, enhancing the audio quality for home speakers and offering an unparalleled listening experience.

The headphone amplifier's innovative built-in voltage boost circuit operates at a high voltage of 24V, despite being powered by a DC 5V source. This ensures a sound quality characterized by a silent background, stunning purity, and transparency, along with precise audio positioning and an expansive sound field. The result is an audio device that not only delivers unrivaled sound quality but is also remarkably easy to use.

The U10 features two 6A2 tubes that add a warm, natural touch to your audio, providing a full, mellow, and sweet sound. The pluggable design of both the tubes and operational amplifiers (op-amps) allows for easy tube rolling and op-amp upgrading, enabling users to shape their sound to preference and enjoy a variety of sound styles. This design caters to audiophiles who appreciate the ability to customize their listening experience.

Housed in a robust all-metal case with excellent shielding, the U10 ensures top-notch sound quality. It features a pure ceramic tube socket with antioxidant contact, which adds to the durability and longevity of the device. Despite its compact size, the U10 delivers powerful sound and offers exceptional value for audiophiles who enjoy vocals, string music, light, or classic music genres.

The included matched pair of low-noise 7-Pin United States GE JAN 5654W tubes are considered one of the best in the 5654 / 6AK5 / EF95 family for audio use. These vintage US-manufactured GE tubes are Mil. Spec. (JAN) Electron Tubes, boasting higher durability and extended life.
