Young Brunette Girl With A Modern Hi-fi System

This modularity allows the enthusiast to spend as little or as much as he wants on a component that suits his specific needs. In a system built from separates, sometimes a failure on one component still allows partial use of the rest of the system. A repair of an integrated system, though, means complete lack of use of the system.
Another advantage of modularity is the ability to spend one's money on only a few core components at first and then later add additional components to one's system. Some of the disadvantages of this approach are increased cost, complexity, and space required for the components.
