Amplifiers and receivers have different functions and purposes in a sound system, which contributes to the difference in their costs. An amplifier is a component that takes the audio signal from the receiver and boosts it, making it strong enough to drive the speakers. It is typically more expensive because it is designed to have a very high power output and to operate efficiently at that power level. It has a limited set of features and functions focusing only on power amplification. On the other hand, a receiver is a more complex and multifunctional unit that not only amplifies the signal but also decodes and processes it. It has built-in features like tuners, pre-amps, crossovers, and various inputs and outputs, which add to the production costs. It also needs to have a more sophisticated and durable build quality to house all these features and to handle the heat produced during its operation.
