Which is better, class A power amplifier or courage machine?

Class A power amplifier is the best one at present. Courage is a class A amplifier, and transistors are also class A amplifiers. Class A power amplifier has the advantages of good sound quality and low distortion. Disadvantages are high cost, high price, high power consumption and low efficiency.

This condition is not easy to compare. Gallbladder and Class A power amplifiers are also divided into high, medium, low and low Class A power amplifiers, which are definitely worse than those above the intermediate level. Only in the case of the same grade and price, class A power amplifier is better than bold machine. The advantage lies in the extension of high and low frequencies, and the roundness and elasticity of speed and bass are better.

Class A power amplifier has the best sound quality, which is much better than ordinary class B power amplifier (98% of power amplifiers in the market are class B power amplifiers, with large distortion and poor sound quality). Bold machine is a class A power amplifier, so it has low distortion and good sound quality. But the bass is poor and the power is low, which is not as good as transistor class A power amplifier.

Courage is better, especially at low prices. Courage is more obvious. A large group of friends I know listen to courage. The real A-class stone machine is difficult and expensive. Small dynamic sound can be Class A, but the current can't keep up with big dynamic sound. This is the weakness of the crystal machine, and the distortion is very ugly.

It depends on what kind of songs you listen to. Traditional folk songs are suitable for electron tubes, not for those pop songs that explode. The transistor class A player is suitable for listening to almost all kinds of songs.
