Bearotti: You may want to further your knowledge by looking at texts and articles from other than manufacturers of audio equipment. Those sources are generally biased to promote their product and do not provide a complete picture. Keep in mind that there is nothing particularly difficult in processing audio signals. Techniques that work in one area of signal processing work in other areas. For eg. in the mid 1990's I spent considerable time on a design project which applied signal processing ideas initially developed in radar target identification to extracting late potentials in ECG signals as an early predictor of cardiac problems.
Also keep in mind that in some 'perfect' sense there are tradeoffs in such things as class a vs class ab amps. However, those tradeoffs are meaningless because - as I indicate above - properly designed AB amps will not result in signal degradation that is in any way noticeable (unless of course one uses the magic 'audiophile ear').
A good beginning point for gaining more knowledge are the books by Douglas Self. These have very little mathematics in the explanation and are readily understood by anyone with a high school math background. The same goes for amateur radio publications. (Engineering texts and publications require a minimum of a formal course, or the equivalent, in differential equations and some background in Fourier analysis - which takes a considerable time investment - generally not a good investment unless one expects to make a living as an engineer)
