Technical Features:
• Class A fully balanced design, the left and right channels are divided into regions, and the left and right separation is good.

• Native full balance architecture, from input to volume control to amplifier circuit, without any conversion, complete four-way architecture.

• Op amp + discrete hybrid architecture, ensuring circuit consistency and no lack of adjustability. Two in-line LM49860 dual op amps can be replaced to increase playability.

• Discrete diamond-shaped differential output stage to easily drive various back-end loads.

• The volume of matrix relay is used to effectively ensure that the volume of 4 channels is consistent and unbiased.

• Adjustable input stage gain and output stage gain, easy to match different front and rear ends.

• Large OLED display + full-featured remote control operation, user-friendly design.

• Customized 50W audio dedicated toroidal transformer.

• All-aluminum alloy case, available in all silver and all black colors.

Rigorous design, reasonable layout, nice workmanship and solid materials.
