Reasonable tube design: choosing 6N2 and 6P1 vacuum tubes to amplify the signal and power, and 6Z4 as rectifier tube. Each tube has been tested to ensure good performance. Pluggable tube design provides much more playability. Pure audio experience: adopting single-ended circuit, working status remains class A and output power is 4W+4W. Superior sound quality, and excellent transient response, providing a premium audio experience with reliability and efficiency. .
