RE: Speaking about solid state amps...

I hear what you are saying but I'm not sure that's true.

A designer of a Class A transistor amplifier will choose a transistor, it's collector voltage and it's idle current based on an 8 ohm load so that the transfer function is as good as it can be.

The operating points of that same transistor used in a Class A/B amplifier will be comprised vs the true Class A design.

Again, the so called "A" part of a Class A/B amplifier is not the same as the "A" part (the only part) of a true Class A amplifier.

There's really no sense pretending that they are the same.

Class A is it's own thing.

Class A/B is it's own thing.

The so called "A" part of Class A/B is not Class A but instead just part of Class A/B.

Keep this in mind. There is always some leakage current but that does not make a Class C amplifier a Class A amplifier (or a Class A/B amplifier for that matter).

Each class of operation has it's own rules and it's own purpose.
