The 10 Best Stereo Amplifier Under 500$ in 2023: Expert's Top Choices

An essential part of a speaker device in our life-demand nowadays is the stereo amplifier. The article will introduce you to the best stereo amplifier under 500 that you can find on the market and focus on the key factors you should keep in mind when shopping. Let’s find out the best stereo amplifiers under $500 for 2021 in the article. 

Overall, an amplifier is an important device in a sound setup system and the amplifier has the function of receiving input signals from the vocal head, karaoke microphone then processing these signals and amplifying the speaker. 

Without an amplifier, your speakers or headphones cannot play. So as to play a sound, you will need a combination of the components listed above to get started. Depending on the setup you are looking to create there are several options for you to consider in the top list of the best stereo amplifiers under 500$ below. 

Some of the components are built into each other allowing for a more compact setup and the setup you choose will largely be determined by budget, the physical space you have available, integration with other home audio components, and the type of music experience you are finding out.

Holding tightly which products top the list of the best stereo amplifiers under $500 is not enough to help you with your final decision, because it belongs to your favorites and your own heart-feeling.

With the purpose to clarify your decision, in this next section we will guide you through what should be on your mind when you go out searching for the best stereo amplifier under 500. We hope that what’s discussed below will be helpful for you.

1. System matching

In the first word, an amplifier’s partnership with stereo speakers is extremely important, and there are some things worth considering to make sure that they complement each other as well as Wensleydale cheese and wheat crackers.

Next, the speaker/amp partnership not only comes down to an amplifier’s power output such as how many watts it can transform to each channel of a music signal?  but it is also impedance (measured in ohms) and sensitivity (dB).

You should clearly know that the standard way to measure an amplifier’s output is by connecting it to an 8-ohm resistor as well as measuring the power before distortion becomes too high. However, the electronic load of a speaker is far more varied than a simple resistor, we’d be careful about judging the strength of an amplifier simply by the 8-ohm power figure.

2. Placement

When you find a catchy device in the list of the best stereo amplifiers under 500, the first thing that comes in your mind might be where do you put it?

Remember that the surface your stereo amp sits on can make the world of difference to its performance. IKEA furniture might not be at the bottom of our list (that’s the floor), but we’d strongly suggest putting it on a dedicated hi-fi rack. Besides, your choice of rack shouldn't be based on looks alone because different materials have different acoustic properties, so take that into consideration too.

Plus, glass shelves tend to encourage kit to sound forward, while wooden supports tend to result in a warmer and more rounded balance.

So that all that power under its hood can build up quite a temperature, so it’s also important to give an amp a few inches of breathing space from a wall or rack to stop it running too hot or overheating.

3. Connections

Before backing to reality, it’s worth looking at your stereo amp’s rear panel to see what options are available regarding connecting sources, extra speakers as well as future upgrades. There are some notes you should keep in mind below.

All stereo amps have line level RCA inputs, which can be used for all the usual sources – music streams, CDs and so on. Moreover, one of those RCA connections is sometimes a phono input, designed specifically to be connected to a turntable and handle the very low signal levels as well as extra equalisation required for such a source of your setup system.

Besides, it has three-pin XLR connections, which carry balanced audio signals. These are usually found in a recording studio and most higher-end products. Its main usage is that it will reject high levels of electrical noise and thus makes the most sense when used in electrically noisy environments or some elsewhere such as over very long cable runs, say 10m or more. Therefore, balanced operation doesn't always sound better, though, and much depends on the components used.

Another part of the connection - Rega is among the brands to have stuck to analogue-only amplifiers, with its multi-Award-winning io, Brio, Elex-R as well as Elic-R models. But, even at the budget end of the market, a lot of stereo amps now feature a digital-to-analogue converter (DAC) – and thus digital inputs – to increase their versatility.

4. Bi-amping

Continuing to the next one, when shopping, there’s also the option of bi-amping , which requires at least two stereo power amplifiers (if you don’t have a multi-channel receiver with spare channels) and some more cables.

We suggest each amplifier handles certain frequencies or channels, instead of one handling it all. So that by reducing the number of drive units an amp needs to power, you could make its job easier and it sounds better.

5. Upgrades

Meaning of upgrading means that upgrading doesn’t necessarily mean out with the old, in with the new. Your amplifier might already have an upgrade path the very first time you possess it.

For example, some manufacturers have dedicated connections for adding external power supplies. If an integrated amplifier has pre-amp outputs, using it solely as a pre-amp and passing amplification duties onto another amp, is another great way to expand.

There’s also the option to upgrade your amplifier’s mains cable, so we’d make use of the fact most dealers will let you try before you buy.

Whatever the rest of your hi-fi system, your future plan for it, introducing a new stereo amplifier requires some thought and a bit of advanced planning.

If you keep in mind everything from the type of equipment your amp is going to be paired with, to the type of rack you will put the thing on, and consider your options for future upgrades, then you’re destined to make the most of your amplifier.

At the time you end up deciding, it’s always best practice to test the stereo amplifier you’re thinking of buying with the kit you’re going to pair it with in the top list of the best stereo amplifier under 500. 

It might be irritating having to take your whole device to a dealership, but it’s the only way you can really make sure how a stereo amplifier will create the sound once you possess it, and your dealer might well have some good suggestions that you hadn’t considered.

1. Can I amplify my factory speakers?

We suggest that adding an amplifier to factory speakers isn’t always a good idea but sometimes you have to. The vehicle manufacturer selected these speakers, meaning they weren’t high on the priority list, and they may have some characteristic that makes them incompatible with aftermarket amplifiers.  If you’re wanting better high-quality sound and thinking of an amplifier, it’s good to upgrade to powerful and compatible speakers as well.

2. Do I need an amplifier if I’ve upgraded my speakers?

It belongs to your budget and what sound you really want. Even if you’ve upgraded your car’s sound system with the very latest head unit and speakers, it won’t make much difference to your overall sound if you’re not providing it with enough power. 

3. How many channels do I need?

About this question, it really depends on what you want to power or how many speakers you need to power because Amplifiers are categorized by the number of ‘channels’, or speakers, they can power. And a one-channel, or mono amplifier, can power a single speaker. 

It is standardly used to power a subwoofer. More details: Two-channel amplifiers can power two speakers, so you can guess how many speakers a four-channel amplifier can power. There are also five-channel amplifiers that can power your entire system (2 front speakers, 2 rear speakers, and a sub).

4. How do I shop for an Amplifier?

With our reviews, and considering our list of the best stereo amplifiers; make sure to match the power output of the amplifier to the power handling of your speakers. If your front as well as rear speakers have slightly different power handling ratings, use the lower rating and find an amplifier that comes close to that. It is not too difficult in this situation.

5. If I add an amplifier and new speakers, do I have to get a new head unit too?

The answer is not, if you don’t want to. If you’d prefer to keep the factory look to your vehicle, or your cars, and so on, you can certainly just upgrade your speakers and add an amplifier to improve your sound. In fact, many amplifiers can actually integrate with factory radios...
