The "differential speaker output" is really a bridged speaker output that drives both speaker wires so that the voltage swing is doubled then the current is also doubled resulting in almost 4 times the power of a single-ended amplifier …

conversion of single ended audio input to differential ...

The vintage way of getting differential audio signals from a single-ended input consisted of merely using an audio frequency transformer, usually a 2 pin input 3 pin output little thing, with a 1:1 turns ratio. The single-ended signal feeds the transformer input, and the output side is a differential signal pair you can bias to wherever you need it to be - connect the middle pin of …
Balanced and Differential - Hairball Audio
https://www.hairballaudio.com/blog/resources/diy-resources/balanced-and-differential
The differential input senses a signal by measuring the voltage difference between conductors. Signal voltages common to both conductors (the noise) are ignored. So in an impedance balanced line that has a 1V signal on one conductor and no signal on the other (0V), the input would pass a 1V signal ( the difference between the two conductors). This is an example of a …

A true differential input provides a higher sound quality than a differential signal going into one amplifier. The true differential amplifier requires an additional circuit to produce the differential input from a single-ended signal. The easiest implementation for the audio amplifier is the signal into one amplifier (Fig. 3). In single-ended mode, the differential input …

AIN(-) are both non-zero. The output code of the ADC will be a function of the differential voltage, AIN(+) - AIN(-). The pseudo-differential inputs cancel out the DC common-mode voltage. To ensure AIN(-) is stable to within ±0.1LSB, bypass AIN(-) to analog ground with a 0.1µF capacitor. Figure 7. Wheatstone bridge application. Single-Ended Inputs
