Details:

New upgrade, comprehensive AP assisted design and testing tuning, and comprehensive sound testing.

Using fully symmetric X-Amp ultra fast power amplifier circuit.

No audio input/decoupling capacitor, pure DC design, wide range of high and low frequencies.

Excellent control force, this machine has a high damping coefficient and strong control force.

This amplifier has high resolution, balanced and transparent sound in high, medium, and low frequencies.

Use 500W Nippon Steel core transformer.

Equipped with comprehensive horn protection function.

Use 4 pairs of precision pairing C2922/A1216. (2 pairs of strong thrust per channel, sufficient to drive the Floor standing speaker)

Use 12pcs 10000uF Rubycon electrolytic capacitors made in Japan.

The left and right channels are designed completely independently to reduce crosstalk interference.

Use Class A high static current design, the sound is warm and comfortable.

Use CNC to process all aluminum chassis.
