Douk Audio E2 is an innovative tube headphone amplifier that merges robust performance, adaptability, and elegant aesthetics. It features dual TPA6120 chips, delivering an impressive output power of up to 2000 mW. This amplifier is designed to accommodate headphones with impedances ranging from 16 to 600 Ohms and offers compatibility with XLR, 4.4 mm, and 6.35 mm connectors. Additionally, the package includes a 6.35 mm to 3.5 mm adapter, ensuring compatibility with a wide variety of headphone models.
The E2 functions effectively as a preamplifier, featuring two RCA inputs and user-friendly switches for audio source selection. It excels in amplifying headphones while also serving as a preamplifier, allowing both functions to operate simultaneously for enhanced audio system versatility.
A notable aspect of the Douk Audio E2 is the inclusion of the German Valvo ECF801 tube, renowned for its exceptional quality and scarcity. This military-grade tube operates at an internal voltage of up to 175 V, delivering a rich, tube-like sound that is highly valued by analog audio enthusiasts.
The device’s design merges classic and contemporary elements: vintage tubes, a VU meter, and walnut wood panels seamlessly integrate with a robust aluminum chassis. This aesthetic appeal makes the E2 suitable for both home audio setups and professional studio environments.
Users can personalize their sound experience by replacing the LME49720 operational amplifier. The device is equipped with a Japanese ALPS potentiometer and German WIMA capacitors, ensuring reliable performance and high sound fidelity.
Features
- WIMA capacitors are reused as new ones are difficult to obtain.
- The operating voltage of the device is 15 V (not less than 3 A). Deviations may adversely affect the operation.
