Product Details:
The by290 amplifier refers to the mature and stable Goldmund circuit design, with a wide sound field, sweet tone, rich and powerful low-frequency sound, full frequency transparency and good layering, and full music flavor.
All aluminum alloy chassis, surface treated with oxidation and wire drawing.
Fully symmetrical design, the overall layout conforms to electrical characteristics.
Two 600W pure copper ring transformers independently supply power to the left and right channels.
8 pieces of 10000uf ELNA filter capacitors.
Equipped with remote control function, easy to operate.
Each channel uses 4 pairs of ON transistors.
