A Comparison of Digital Power Amplifiers with Conventional Linear Technology: Performance, Function and Application

Drawing conclusions about the actual subjective performance of an amplifier from the results of standard tests can be difficult. The measured results for the harmonic distortion and inter-modulation distortion in the case of the linear amplifier are excellent and exceed those of the digital amplifier. However, a subjective assessment with music material ranked the digital amplifier performance as superior. More investigation was required.
