Explain Class A amp to non audiophile friends


How do I explain a Class A amplifier and a Class A/B amplifier to my non audiophile friends? I tried by saying a Class-A amplifier power devices are conducting a continuous current meaning they are always on. They did not understand and maybe neither do I.

Can someone please explain how a Class A amplifier works vs a Class A/B amp in non technical terms so I can explain it to my friends.

Hi all ! Here is my standard answer....like driving a car , in class AB you drive around and vary speed with the gas pedal . In class A you hold the gas pedal to the floor and use the clutch to vary your speed . Not perfect , but effective .
