It does matter.

Home background music systems are mainly divided into fixed resistance and constant voltage types. In order to ensure the listening effect and fidelity of high-quality background music, the resistance is fixed. Often independent areas can be controlled independently. The audio source can be independently selected and controlled.

The host is not a simple power amplifier. The host has a built-in sound source, power amplifier display and control system. One power amplifier display is equivalent to multiple independent power amplifiers. Using the power amplifier series will not reduce the sound quality as the music points increase.
