Method for generating an amplified high-power alternating voltage that follows a digital input data stream in terms of shape and amplitude, preferably in the known I2S format, whereby a direct-voltage supply that takes an essentially sine-shaped current is provided as the power supply. In order to achieve a high degree of effectiveness and a high level of congruency between the input data stream and the output signal, it is provided that the input data stream is converted into a digital signal sequence, and this signal sequence is amplified by switching, whereby a digital signal is derived from the amplified output signal, and compared with a digital signal that corresponds to the input data stream, and the amplification of the input data stream is influenced, in the sense of a congruency of the amplified signal with the input data stream, by means of switching by a digital difference signal that might be determined, whereby a signal that corresponds to the ripple of the direct-voltage supply is mixed into the input data stream or a signal derived from it.
