Actually difference between class A and AB?

Class A amp sounds like holy grail of HIFI world.
But class A amp are much heavier, more expensive and rarer than class AB or class B design. Few can afford 100 LB weight of a 2-channel 100w/c amp.

Is there any actual difference between class A and class AB when listening to actual music? And what is that difference?

Newer Class Ds done well may be the emerging holy grail for most in terms of overall performance, efficiency, and cost of ownership. Maybe even just on performance alone, the rest aside.

I am not a Class A/B fan anymore in general.

Class A is good but practical for most only in certain cases.

I've had older Class G rail switching amps also. Those were smaller and more efficient also but also very mediocre with a compromised design, like much Class A/B perhaps.
More to discover
