• It can be connected with mobile phones, laptops, tablet computers and other devices with Bluetooth wireless digital audio; it can also be connected with iPod, iPhone, iPad, CD, DVD, and TV HD set-top boxes for digital or chess analog audio;

• With optical fiber, coaxial digital signal input interface, and 24Bit/192K digital-to-analog conversion accuracy;

• The pre-amplification part adopts 12AX7 electron tube common-cathode amplifier circuit, and 12AU7 electron tube serves as SRPP for buffer amplification;

• Electron tube and transistor hybrid precision high-voltage regulated power supply. The voltage stability is extremely high, the AC ripple coefficient is extremely low, and the sound performance is more "bright";

• The power amplifier part is composed of high-power transistors to form a 0dB current amplifier circuit. The sound is warm and sweet, and the sound energy and dynamic performance are excellent. It can easily drive a variety of advanced brand speakers;

• The tube circuit cross-connect capacitors all adopt advanced MKP audio dedicated capacitors, which have excellent performance in both timbre and sound field, and play an important role in improving sound quality

• Adopting Japanese ALPS large remote control volume potentiometer, which has the characteristics of low noise, no sound staining, and less error between two channels;

• Equipped with an equal loudness switch function, which can improve the performance of high and low sounds at low volume;

• The output adopts large gold-plated binding posts, which can be easily connected to any speaker wire
