Start from the audio unit

Every part is related to sound quality

A typical audio unit is basically composed of these 8 main components. The design structure, materials used and processing technology of each component have a vital influence on the tone color and sound quality. Among the above three aspects, the use of materials has the greatest impact on tone color and sound quality; the ever-changing relationship between them gives each audio unit a completely different tone color and sound quality. Even with the assistance of a supercomputer in the early stage to simulate the working conditions of the sound unit to obtain a combination of three aspects with good theoretical indicators, the amount of calculation required is very huge, and then some combinations have to be selected for objective verification of the working conditions And subjective audition of timbre and sound quality. It is not difficult to imagine and understand how many engineers' time and efforts have been spent behind the birth of each excellent audio unit. This is also the reason why excellent audio units are expensive.
