What is a primary advantage of a digital amplifier over an analog amplifier?

A primary advantage of a digital amplifier over an analog amplifier is that it typically produces less internal noise and distortion. Digital amplifiers work by converting analog signals into digital data, which allows for more precise processing and control of the sound output. This digital processing can effectively filter out unwanted noise and reduce distortion that can occur in analog systems, leading to clearer and more accurate sound reproduction.

In contrast, while there are benefits associated with the cost of production, design simplicity, and power consumption of various amplifier types, these factors do not consistently apply to digital amplifiers across the board as they do with the reduced noise and distortion capabilities. Therefore, the superior sound quality achieved through less internal noise and distortion remains the standout advantage of digital amplifiers in the context of audio applications like hearing aids.
