Established in 2013, Douk Audio & Nobsound is a brand created by a group of enthusiastic music fans and professional audio experts. Their aim is to "Make Hi-Fi Affordable" by designing and producing various audio equipment, including amplifiers, phono preamps, headphone amps, DACs, audio switches, and more.

Douk Audio is committed to providing the most cost-effective products and the highest level of service. They have been supplying audio products to hundreds of countries, offering thousands of different products under their own brands, such as "Douk Audio," "Nobsound," and "Little Bear."

The Nobsound Magic Eye 6E2 EM87 Tube Preamp is one of their products. It features a 6E2 tube magic eye driver board that adopts Douk Audio's core power technology, making it more convenient and simple to use, while also effectively reducing the circuit's power consumption. The PCB uses a large number of SMT components, and the device can be powered by a DC (5V-7V) power supply or directly from a standard USB 5V source, such as a mobile phone charger or computer USB interface.

The Nobsound Magic Eye has a reasonable PCB size optimization, reducing the chassis space occupied, and the wiring is simple and clear. The potentiometer is provided with a level display range adjustment, making it more convenient to adjust. The device has a built-in secondary signal amplification, providing higher sensitivity, and an adjustable level display.

Additionally, the Nobsound Magic Eye has a built-in electronic boost circuit, eliminating the need for a 250V transformer required by traditional driver boards, saving money and space. The finished board has been burn-in tested and can be used directly upon receipt.

The Nobsound Magic Eye can be used as an audio level indicator or a VU meter, allowing users to see the tube light dancing with their audio signal. It can be used separately or combined with other devices, making it a useful and visually appealing addition to any audio setup.

The device's advantages include reduced heating, lower power consumption, and a smaller size compared to similar products. It also features SMT technology, which decreases the height of all circuit components and optimizes the layout for simpler wiring. The built-in secondary signal amplification and adjustable amplitude provide higher sensitivity and customization options.

Overall, the Nobsound Magic Eye 6E2 EM87 Tube Preamp is a cost-effective and feature-rich audio accessory that aligns with Douk Audio & Nobsound's mission to "Make Hi-Fi Affordable" for music enthusiasts.
