• Split power supply design

Using high-quality linear power supply, five core external power connector, dual power supply, large-capacity capacitor filter and more effective to reduce power supply noise

• New circuit architecture modular design

Modular functional design, the independent power supply modules at all levels using high-quality regulator chip, effectively avoiding the crosstalk between the signal;

Intimate delay protection design, delay access to the amp and shut down quickly to disconnect , avoiding completely the impact of the DC output of the switch machine instantly circuit imbalance to protect your expensive headphones and speakers;

• tube buffer stage design

Use Dawn of high-quality 6N11 vacuum tube, vacuum tube warm sound and digital audio complement each other, elegant white tones warm hearts! • careful component selection

Use high quality components, and Japan ALPS potentiometer, the German WIMA capacitors, four precision chip resistors, sound special ENLA electrolytic capacitors, tube, USB port, RCA terminals are gold-plated material, full ON regulator device.

Amp output gain adjustment, replace the amp module

Amp specifically designed for replaceable modules, in particular, to increase the output gain adjustment switch, you can push a variety of sensitivity headphones, optional wide range of headphones!
