Douk Audio T4 PRO Tube MM Phono Preamp & Headphone Amp with Extra Vacuum Tubes

The Douk Audio T4 PRO phono preamp you receive will include one unit and an extra pair of GE5654 tubes, along with all the original accessories. This T4 PRO tube preamp caters to a wide range of HiFi needs - it features an MM phono input that converts the phono signal to a line-level signal, utilizing low-noise integrated circuits and high-quality components to ensure clear, clean sound. Additionally, a 3.5mm AUX input allows you to amplify low-level audio signals from your phone, tablet, PC, MP3 player, and more, making it easier to drive an amplifier or active speaker and significantly improving the sound quality.

The T4 PRO comes equipped with imported JAN5654 tubes, which deliver a vintage, warm sound. These tubes enhance various aspects of your music, such as detail, transparency, immediacy, richness, dynamics, and tone, providing a much-improved performance over the 6J1 series, particularly in the reproduction of the human voice. The tube socket is designed to be easily interchangeable, allowing you to experiment with different tubes and shape the sound signature to your personal preference.

Additionally, the T4 PRO features a 3.5mm headphone output and a well-designed circuit. The built-in classic headphone amplifier circuit (2*NE5532) can easily drive 32-300 ohm headphones. The architecture of the preamp is both reasonable and advanced, utilizing TI TPA5430 for power management and TL071+JRC2068 for the phono preamp circuit. This allows you to enjoy high-fidelity analog sound and first-class design at an unbeatable low cost.

The compact T4 PRO is designed with attention to detail, featuring a solid aluminum knob and a potentiometer for smooth, multilevel gain adjustment. The grey, integrated molded aluminum alloy shell is adorned with a special red tube cover and knob, giving the unit a vintage and elegant appearance. Despite its small size, the T4 PRO will provide you with a different acoustic experience, delivering a large dynamic range and a sweet tube sound, even in limited spaces.

Lastly, the pair of low-noise 7-Pin United States GE JAN 5654W tubes included with the T4 PRO are considered among the best in the 5654 / 6AK5 / EF95 family for audio use. These vintage, US-manufactured GE tubes are Mil. Spec. (JAN) Electron Tubes, ensuring higher durability and longer life.
