What you're describing is single-ended vs. push-pull. Class A means that all of the output transistors or tubes ARE BIASED TO IDLE AT FULL POWER ALL THE TIME (unless their bias is computer controlled, like the Krell FPB series). EITHER SINGLE ENDED, OR BALANCED CIRCUITS CAN OPERATE IN CLASS A. Class AB means that the output devices are partially (but not fully) powered up all the time. BOTH "Emily" and "SteveM" NEED TO READ "THE COMPLETE GUIDE TO HIGHEND AUDIO"...
