@invalid S300 output is supplied from single supply only. To achieve net zero output at 50% duty cycle speaker is "flipped" between V+ and GND by bridge of 4 Mosfet transistors. Some modules achieve it with dual +/- supply and only 2 Mosfets. To me it is more "bridged" than "balanced", but it doesn't matter, as long as we know what it is.

I understand that intuitively what you wrote seems "true," that it "feels" like it's correct. But it is completely false. You don’t know what you’re talking about. Here’s a guy who actually understands balanced circuits and who notes the myth of your claim. (I suspect you’ll reject this, just as you have the information I’ve quoted from other manufacturers. I’m including it for the benefit of others): Balanced line equipment is often also fully differential, like our amps and preamps. A differential amplifier has two inputs, and in theory only amplifies what is different between those two inputs ... A differential circuit isn’t double the number of parts of a single-ended circuit, although it does have more parts. |
@cleeds He talks about benefits of balanced cables and differential inputs. It has nothing to do with "Fully balanced power amplifier" vs power amplifier with balanced differential inputs. I will leave it at that. |
Actually, it has everything to do with "fully balanced" amplifiers, and @atmasphere is especially well known for his balanced amps. Owner Ralph Karstens even holds an interesting patent covering his topology. I've now provided to you three original sources that reveal your beliefs to be myths. |
