Abstract
A digital-to-analog conversion device for converting a digital signal to an analog signal for amplification by an audio amplifier. The conversion device has a solid state digital-to-analog converter and a filter connected to the output of the digital-to-analog converter. The filter comprises n passive components where n is a number of at least two, arranged so as to form an nth order filter for reducing the quantization of the output of the digital-to-analog converter.
