Adding a separate amplifier and speakers can help improve the sound quality of any home theatre system, which is something that we covered in the guide that we wrote on how to put up surround sound.

When looking at amplifiers to increase the sound of your TV, however, you primarily have two options: you may get a stereo amplifier/receiver for stereo audio or an AV amplifier/receiver for multichannel audio. Both of these options are available to you. The use of stereo amplifiers and receivers is something that we shall go into in this article. Take a look at my rundown of the top AV receivers for home theatres if you are more concerned about surround sound.

What Exactly Is a Stereo Amplifier?

Stereo amplifiers, often referred to as stereo receivers, are electronic devices that amplify audio signals coming from a source like a CD player or a turntable and then send those signals to a pair of speakers so that sound can be produced. Stereo amplifiers create a sense of spatiality and directionality in the sound by processing two separate audio channels, left and right, as opposed to mono amplifiers, which only process a single channel. This is what gives stereo amplifiers their name; mono amplifiers only process a single channel.


There is a wide range of sizes and shapes available for stereo amplifiers. These range from small, portable devices that can be placed on a bookshelf to bigger, free-standing components that require a considerable amount of room to operate well. They can also come with a variety of features and inputs, including as phono inputs for turntables, USB inputs, coaxial inputs, and optical inputs for digital sources, among other possible configurations.

The amplifier stage is located at the very centre of a stereo amplifier. It is responsible for amplifying the incoming audio signal by employing vacuum tubes, transistors, or a combination of the two. After the amplifier stage comes the preamp stage. This stage is responsible for equalising the audio stream as well as adjusting the volume and tone controls.


The signal that has been amplified and equalised is then sent to the speakers via the power amplifier stage, which supplies the necessary power to drive the speakers and produce sound. Because it is responsible for determining both the overall sound quality and the volume level of the system, the power amplifier stage is the most important part of a stereo amplifier.

A stereo amplifier gives the user a greater degree of control over the sound that is being produced, which is one of the device’s primary benefits. Users are able to more precisely tailor the sound to their tastes and create a more immersive listening experience when independent settings for volume, tone, and balance are provided. In addition, a wide variety of stereo amplifiers come equipped with equalisers and filters that can be used to further tailor the sound to the user’s preferences.


A source device can be connected directly to a pair of speakers, but a stereo amplifier can drive a pair of speakers to produce sound that is more powerful and dramatic than the sound that can be achieved by doing so. This is one of the advantages of using a stereo amplifier. This is due to the fact that the amplifier supplies the necessary power as well as the current to drive the speakers, in contrast to the source device, which would not have the power to do so.

When compared to the audio processing and amplification that is built into the majority of source devices, stereo amplifiers typically come equipped with improved features such as equalisation and audio processing, in addition to better power management. This allows stereo amplifiers to contribute to an overall improvement in the sound quality of a system. In addition, many stereo amplifiers come with room correction software that may adjust the sound based on the size and layout of the room. This further enhances the listening experience by allowing the music to be customised to the space in which it is played.


In conclusion, stereo amplifiers are vital components for anyone who wants to establish a home audio system of good quality. They provide a higher level of control over the sound, an improvement in the sound quality, and the capacity to power a pair of speakers in order to produce a sound that is both dynamic and strong. Any music enthusiast can find a stereo amplifier that meets their requirements thanks to the wide variety of features, inputs, and customization options now on the market.

What Exactly Is a Stereo Receiver?

The question now is, what precisely differentiates a stereo amplifier from a stereo receiver? A small amount.

When referring to high-fi or home theatre equipment, the term “receiver” actually refers to a 2-channel amplifier that powers your speakers. This is what the term “receiver” implies when you see it used. Why then do we use the word receiver?


Simply put, this indicates that the amplifier also contains an internal radio tuner; the fact that this is the case is the sole reason why it is referred to as a receiver rather than an amplifier. In order for the receiver to receive the radio signal, it will most likely need to be connected to a suitable aerial or antenna. However, you can pick up radio channels on the receiver and transfer this signal to the speakers.

In addition, you will have all of the other 2-channel inputs just like an amplifier, allowing you to connect in your CD, DVD player, PS3, and so on. As part of your home audio system, you might have a radio tuner unit that is a distinct component. However, there is already one of these incorporated inside the stereo receiver.


Aside from that single distinction, an amplifier and a receiver are functionally identical devices. It is possible that you will only use the receiver as an amplifier, and that you will not even make use of the tuner that is built in.

Which Should You Choose: Stereo Or Surround Sound?

If this is the case, then it begs the question: why would you choose a stereo receiver with only two channels over a more sophisticated audio/video receiver with several channels? A few potential theories come to mind at this time.


The first and most convincing argument is that a high-quality two-channel receiver may be able to deliver outstanding sound at a more affordable price.
The amplification of sound is the only purpose served by a stereo receiver that also functions as an amplifier. They will have great audio quality for listening to music, and it is expected that they will also have good audio quality for watching television and watching DVDs. They will be manufactured.

The price of an AV receiver, which is designed to process audio and video data from many channels, is significantly higher when contrasted with the price of a stereo amplifier.


If you are used to listening to music through a stereo amplifier and speakers of a good quality, the audio quality of an AV receiver could not meet up to your expectations, despite the fact that the audio quality of an AV receiver isn’t necessarily awful. It’s possible that the sound on the television and in the movies is OK, but the difference will be noticeable when you listen to music.

There is also the potential that you already own a stereo amplifier of a high grade and that you have previously connected it to a beautiful pair of speakers. This would be an ideal situation. The addition of your audiovisual equipment to your existing setup will not cost you a dollar, and the sound quality will immediately improve as a result of the addition of your high-fidelity amplifier.


Many transmissions available Stereo sound is still used in television, and high-quality stereo mixes are included on all DVDs and Blu-rays. Television still uses stereo sound. This indicates that you are still able to have a greatly increased viewing experience when watching TV, DVDs, or Blu-rays.

Stereo Receivers and Subwoofers

To make a high-quality home audio system, stereo receivers and subwoofers are essential. The term “stereo receiver” refers to an electronic device that takes in audio signals from many inputs and then amplifies them to drive a set of stereo speakers. In contrast, a subwoofer is a type of speaker optimised to reproduce low-frequency sounds like bass that are beyond the capabilities of standard speakers.


If used together, a stereo receiver and subwoofer can produce a full and immersive soundstage, with the former amplifying the midrange and treble sounds and the latter managing the bass. The powerful, deep, and dramatic bass produced by the subwoofer enhances the audio output from the stereo receiver, allowing for improved clarity and separation of sound.

It is common for stereo receivers to have subwoofer outputs, making it simple to hook up a subwoofer. The subwoofer is integrated into the larger sound system and the bass frequencies are balanced with the rest of the audio output by the stereo receiver, which regulates the subwoofer’s volume and frequency range.


Furthermore, some subwoofers have built-in amplifiers, which eliminate the need for an external amplifier and streamline the installation process. These subwoofers are ideal for smaller listening environments like those found in apartments or home theatres since they may be connected directly to the stereo receiver.

What Brands Make the Finest Stereo Receiver?

The best stereo receiver is highly debatable and depends on a wide range of criteria, including the user’s preferences, the sort of audio system being built, and the available money.


Some of the best-known manufacturers of premium stereo receivers are:

  • Marantz When it comes to high-end stereo receivers, few names are as well-respected as Marantz’s.
  • Yamaha is another prestigious name in the audio world, and it’s well-known for making a wide selection of stereo receivers to suit different people’s tastes and budgets.
  • Denon is a premium audio manufacturer that produces a variety of high-end stereo receivers known for their rich tones and flexible setup options.
  • Onkyo The Japanese company Onkyo is renowned for producing robust and flexible stereo receivers.
  • Pioneer The Pioneer brand of stereo receivers is well-known in the audio industry. These receivers include Pioneer’s signature excellent quality and come in a number of models to suit a wide range of listening preferences.

While these are all well-respected names in the audio industry, the finest stereo receiver for you will ultimately come down to personal preference, money, and other factors. A good way to get the right brand and model for your stereo is to do some research and comparison shopping.

How to Shop Smart: Knowing What to Look For

Several important considerations should be made while shopping for a 2-channel amplifier.


Volume and quality of the sound produced by an amplifier are both directly proportional to the amount of power it can generate. The right amplifier can improve the quality of your sound regardless of the size of the room it is in.

When picking an amplifier, it’s crucial to think about the system’s impedance, which is the resistance to electrical current in the audio system. Check the amplifier’s impedance to make sure it’s suitable for your speakers.

The frequency response of an amplifier is what establishes how many different tones it can faithfully reproduce. With a wider range of frequencies covered, the audio produced is more complete and true.


Total Harmonic Distortion (THD) is a metric for assessing the degree of distortion in an amplifier’s output signal. A lower THD means crisper, more precise audio.

What is meant by the term “signal-to-noise ratio” is the comparison of the amount of desired audio signal to the amount of background noise at the amplifier’s output. The sound quality improves with a better signal-to-noise ratio.
Take into account the amplifier’s inputs and outputs to ensure that it works with your other audio equipment.

The durability and dependability of an amplifier are directly tied to the quality of its construction. When shopping for an amplifier, it’s important to think about the components and build quality, as well as the manufacturer’s track record for reliability.


Think about the remote control, tone controls, and balancing controls that the amplifier may have, and prioritise those that are most useful to you.

Keeping these things in mind will help you find the ideal 2-channel amplifier for your specific application and budget.


It’s common to disregard stereo receivers and amplifiers when building a home theatre system.

When looking to upgrade their home theatre experience, many individuals either settle for the sound provided by their TV’s built-in speakers because they are satisfied with it (or they simply don’t know any better) or they immediately get a surround sound AV receiver.

While I personally find the advantages of a surround sound system to be numerous, I do recognise that some people are quite content with stereo sound, especially if they have been accustomed to the excellent sound produced by a good stereo amplifier and speakers.

Don’t rule out the use of a 2-channel amplifier/receiver in your home theatre setup. A high-quality audio experience is possible.
