Stereo amplifiers, or amps for short, receive an electrical signal from your audio system and amplify it, before sending it over to your speakers. The main purpose of any amp is to enlarge or boost the signals that it receives. This boost can improve the loudness of the audio and even the clarity of the audio being played by the speakers. And in some cases, if there are separate audio and speaker setup, the use of a stereo amp is necessary, because it can ensure that the voltage of the electrical signal between the audio system and the speakers match. So if you are setting up your audio system, you may want to purchase a stereo amp, not just to improve quality but to ensure that your whole audio setup works.
How do these work?
The job of a stereo amp is to take an electric current and boost it into a bigger current. And the amp achieves this by allowing a small voltage from the input to pass through a semiconductor or a tube to control it into a much higher voltage. This semiconductor or tube is usually called a flow adjuster. When the input current from the audio system is passed through that flow adjust the amp boosts it with more voltage.
Multiple kinds of stereo amps
To achieve that boost in the audio signal input, there is more than just one type of stereo amp. Each kind of stereo amp may use a specific kind of technology to boost the audio signal. And these stereo amps may also be appropriate for different kinds of specific uses as well. For example, single stereo amps are good for personal use, since you can just connect them alone to your computer or TV, and then to your speakers. There are also higher-grade and more expensive stereo amps that are meant for professional quality audio, such as PA amps and tube amps. You may want to do a bit of research about amps and the kinds that you can buy.

Do you need one?
The obvious question on everyone's minds, is, do I need this kind of thing? There could be a bunch of reasons why you need a stereo amp.
Do you notice any distortion when playing loud audio? If you notice any distortion or loss of sound quality when you play any loud audio from your speakers, then using an amp can quickly solve that issue.
Do you have a subwoofer? If you want to power your subwoofer effectively, it needs a higher voltage audio signal, which a stereo amp can provide.
It is simply a way to improve the overall quality of your new speakers. If you want to get the most out of your top quality speakers at home, you really should get a stereo amp. You would be amazed at the huge improvement in sound quality and loudness that you can get from a stereo amp.
