7: Features of Class A power amplifier: The longer it is turned on, the better the sound quality, that is, the more you listen, the better it sounds. However, the energy consumption of a Class A power amplifier is fixed. When the output of the speaker is larger, the power amplifier loss is smaller, and the use effect is higher. The smaller, and when there is no output (that is, static), the loss of the power amplifier is the largest. Therefore, it is very costly when not listening to music for a long time, and the heat is very large, which reduces the reliability and user experience.
The standby function plays a role in energy saving, safety and prolonging the service life.

8: The small class A power amplifier is the ideal choice for HIFI bookshelf speakers, especially suitable for 5-6 inch bookshelf speakers. It is effortless to push and has strong power.
