AIYIMA T20 Fully Balanced Hi-Fi Tube Preamplifier

True Analog Warmth with Balanced Precision: The Audiophile Tube Preamp

The AIYIMA T20 is a fully balanced vacuum tube preamplifier designed to bridge the gap between digital precision and analog soul. Featuring an authentic 180V high-voltage circuit and swappable tubes, it provides a lush, musical soundstage while maintaining the noise-free performance required for modern high-fidelity systems.

• Fully Balanced Architecture: Utilizes a true balanced circuit design for both XLR and RCA paths, ensuring maximum noise rejection and superior signal integrity.
• 180V High-Voltage Tube Stage: Operates ECC83 (12AX7) tubes at their intended high voltage to deliver genuine harmonic richness and dynamic range.
• Customizable Sound Signature: Features user-swappable vacuum tubes and op-amps (LME49720 & OPA1612), allowing audiophiles to "roll" components to match their sonic preferences.
• Intelligent Soft-Start System: Includes a 20-second warm-up countdown to protect the tubes and internal components, extending the lifespan of the device.
• Seamless System Integration: Equipped with dual 12V trigger outputs to automatically power on/off connected amplifiers or DACs for a streamlined user experience.
