If you're listening to audio from loudspeakers, it's practically guaranteed that there is a power amplifier in the audio signal chain. If you can't see the amplifier unit, it's probably built into the active speaker. If the speaker is passive, it will require a power amplifier. This article is about the latter of the two cases.
The power amplifier(s) of an audio setup is essential in getting the best results. Choosing the right amplifier for your loudspeakers and overall sound system is a big decision. There are so many options out there when it comes to choosing a power amplifier.
