Fully Balanced In/Out, Very Pure Sound

It is a fully balanced circuit from input to output, which greatly improves the Cross- talk, resolution, sound field and SNR, let you enjoy the pure and clear sound.

Large Output Power - Easy to Drive Your Headphone 2000mW!

It has 4-pin XLR and 4.4mm balanced head- phone output, the output power up to 2000mW, can easy drive the headphones with impedance from 16 to 6000, and maximize the performance of your headphones.

Class A Buffer - Tube + Transistor Hybrid Structure

Adopt transistors for class A buffer, strong output power can easily drive many kind head- phones. Tube + Transistor hybrid amplifier structure, It can not only bring exquisite and soft sound, but also give consideration to explosive force and speed.

Multiple input/output - Easily switched as you want

It has two RCA, one XLR and one 4.4mm balanced input, which makes it easy to switch between different sound sources. It has 6.35mm unbalanced, 4.4mm balanced and 4-pin XLR balanced output, adapts to many kinds of headphone plugs and saves the trouble of finding a converter.

Double tube amplification

It uses two classic 12AU7 tubes to process audio, which are rigorous testing and match-ing, it brings the unique warmth and softness of sounds because the tubes, making you not tired of listening for a long time.
