Does a "SET" amplifier and "Class A" mean basically the same thing?

Does a "PUSH-PULL" amplifier and "Class B or AB" mean basically the samething?

If an amplifier is "balanced", does that just mean it has XLR connections?

If an amplifier is "single ended", does that just mean it has RCA connectors?

For example, why do these guys have a "bananced" series and a "single ended" series?

Last question, should I even care?
