Hi! I have a question about this.
There is Class A drive. There is Class AB drive, where the emitter resistor of the driver and pre-driver is connected to the output.
There are also drivers where a B-E resistor is used. What are the differences?
Which one is more stable?
Which one provides better sound quality?
