The ultimate goal of home audio systems is to achieve ideal listening effects, such as enjoying the sound effects of cinemas at home. But families are different from cinemas, so the acoustic effects required for appreciating different types of sound are also different. For popular music, classical music, light music, etc., it is required to be able to correctly reproduce various instruments, but for appreciating movies, it is required to have a sense of liveliness and surround sound effects.

For sound sources, DVD is the preferred choice, as it is a purely digital design and is mostly equipped with an AC-3 interface, which can directly form a Dolby surround sound system with AC-3. The CD player is also good, but it is important to note that different sound sources will ultimately result in different sound effects (even if the devices behind are completely the same).

For power amplifiers, it is required to have multiple pairs of input and output terminals (at least 6 pairs if building a home theater system), a large power output, and impedance matching.

The requirements for speakers can be lower in power, as high power output is generally not required for household use. However, there should be high requirements for the sensitivity, directional characteristics, and frequency response characteristics of speakers. It is best to use a full frequency speaker with sufficient power.

Connecting wires are the most easily overlooked by enthusiasts, but it has been proven that their impact on sound quality cannot be ignored, and their frequency and shielding characteristics must be better.
