An audio system is a set of components that work together to play music, such as a DAC, amplifier and speakers. Here, the listing author brings their listings together on one page to show the components, total price and purchase options — as a complete system or separately.
You do not need to sell a complete audio system: you can group just some components, such as a DAC and an amplifier. Sale conditions apply to the components in the bundle: the listing author chooses whether to sell them only together or also separately.
