The heavier the power amplifier, the better. When we choose other products, we advocate lightweight and small, but the power amplifier requires large weight. Because the power amplifier is mainly driven by a powerful power supply, the quality of the transformer must be too large, and the light weight power amplifier is prone to shrinkage on the power supply, resulting in the loss of music details. Moreover, the heavy power amplifier can reduce the resonance of the box under strong vibration to ensure the fidelity of the sound.
