6N2 tube for preamp

Delivers a smooth and exquisite sound through the use of the 6N2 tube in the preamp stage.


6N5P tube for buffer

Smooths and refines the sound through the use of the 6N5P tube in the buffer stage.


Step potentiometer

Eliminates the problem of volume imbalance with a step potentiometer, ensuring balanced volume levels.


Line output as a preamplifier

Features a line output that functions as a preamplifier for various audio amplifiers or active speakers using the tube and volume control, thereby improving sound quality.


Professional Resistors and Capacitors

Uses xDuoo custom-made metal-polyester film capacitors as coupling capacitors for the tube output, ensuring professional-grade audio performance.


Point-to-point wiring for authentic sound

Uses point-to-point soldering with copper wires to construct the tube circuitry. This method minimizes wiring paths, reduces interference, and ensures a clean circuit, resulting in authentic sound reproduction that remains true to the characteristics of vacuum tubes.


Aluminum alloy chassis with sandblasted finish

Features a high-quality, sandblasted finish and a robust aluminum alloy chassis that is both aesthetically pleasing and provides effective protection against external interference.
