 pairs of transistor switches in accordance with the input signal for forming a differential output signal across a second terminal of the first reactive element and a second terminal of the second reactive element. A low signal level detector is coupled to the second and fourth pair of transistor switches for disabling the second and fourth pair of transistor switches from switching upon detection of a low input signal level condition. The input signal may be an audio signal. The switching amplifier may include a speaker coupled to receive
