• Advanced design of dual mono full balance amplifier circuit, two channels are completely independent; each channel uses an R-type power transformer

• Using ECC803 and ECC802 audio dedicated electronic tubes and supporting gold-plated tube sockets, the sound is sweet and natural, and dynamic

• Tube Class A output buffer with up to 30V undistorted output voltage, easily matching any post-stage power amplifier

• Unbalanced signal input and output terminals use 4 German WBT products, and balanced signal input terminals use Swiss NEUTRIKP products

• The volume controller is made in Japan ALPS large quadruple high precision potentiometer

• The power input socket adopts Japanese Furukawa gold-plated products, and the fuse adopts Swiss Schulte products
