Buying Guide

What Exactly is an Integrated Amplifier?

If you’re looking for the best value when it comes to stereo power amplifiers, you’re probably going to want to go with an integrated option.

These convenient amplifiers house two main components in one system, as opposed to having each component in its own housing. In an integrated amplifier, the stereo power amplifier and the preamplifier and housed together. The main difference between these two components is this:

  • The stereo power amplifier is what actually powers your speakers by providing wattage.
  • The preamplifier is where the input from any of your audio sources is directed as it reaches the amplifier.

Having these components in one chassis instead of two allows the entire amplifier to be controlled more easily, even for beginners. This guide will help you find the best integrated amplifier under 500.

Why Use a Stereo Amplifier

With an amplifier, you can create powerful audio from a less than powerful source. If you connect an audio source, such as a computer, television, phone, smartphone, etc., directly to a speaker, the speakers can only play the audio at a certain volume and quality level. Even if the speakers are high-quality, they can’t perform up to their potential when connected to a low-power input source.

Best Stereo Amplifier

An amplifier acts as a middle man between these two devices. The input audio source is made more powerful, or amplified, before it is delivered to the output speakers or headphones. This allows you to get the most out of your audio and experience high-quality sound the way your speakers were intended to deliver it.

What to Consider Before Buying a Stereo Amplifier

Input Connectivity Options

Before buying a stereo power amplifier, it is important to consider how exactly you’d like to connect your music or audio source to it. Here are a few connection options that you’ll typically see with integrated amplifiers:

  • Wired Connection: While a lot of options these days feature wireless connections, some do still require actual input and output cables between the amplifier and the music or audio source.
  • Wi-Fi Connection: Some stereo amplifiers can be connected to via your wireless internet connection. Simply connect both the audio source as well as the amplifier to your wi-fi router, and you’ll be able to stream from online.
  • Bluetooth Connection: Some amplifiers are Bluetooth compatible, allowing you to stream music or audio on them from any other Bluetooth compatible device.

Output Compatibility

Once you know that the amplifier you are considering allows for you to input and stream audio in the way that best suits you, you’ll want to see if it has output options that work for you.

Not all amplifiers offer the same output features, so it’s important to keep in mind how you typically stream your audio. Here are the common output options you can look for when buying a stereo amplifier:

  • Speaker Connectors: If you’ll be playing music on speakers, look for an amplifier with a speaker connection. A lot of options will even include two separate output port pairs for speakers, so you can power speakers in another room as well.
  • Subwoofer Connection: If deep and rich bass is what you’re after in your audio, then an amplifier with subwoofer compatibility may be what you’re looking for.
  • Headphone Output Jack: If you spend a lot of time listening to your audio or music with headphones on rather than through speakers, then it’s important to choose an amplifier that actually includes a headphone jack. Not all do.


Most stereo amplifiers, especially in the under $500 price range, are relatively small. Still, size can be an important thing to consider before your purchase if you want a certain number of connections options or are fitting the amplifier in a tight space.

A larger amplifier obviously can fit more input and output ports along the back side of the housing. These can be a great option if you want the most versatility out of your amplifier or if you intend to stream audio from or to more than one source or device.

A smaller amplifier will offer less versatility, but this won’t matter much if you find one with exactly the input and output options you intend to use. They are a great option for smaller spaces.

Integrated vs. Pre/Power Amps

The primary advantage of an integrated amp is that it does two jobs at the same time, namely the work of the power amp and the pre-amplifier. Finding the best integrated amplifier under 500 means you’ll be getting this dual-capacity benefit built into your new system. In most cases, integrated amps use just one power supply for both functions, but that’s now always true. It depends on the system.

What goes on inside your integrated amp system? For starters, you’ll get volume control, with two key additions: source switching and amplification. Most people who own integrated amps say the beauty of the devices, asides from technical features, is simplicity. That’s because everything happens in one box.

The cost advantages of integrated amps makes sense for dollar-conscious consumers. You can power your speaker system and augment any home theater or multi-zone arrangement with ease.

RMS vs. Peak Wattage

Without getting lost in the weeds of technical jargon and deep science, it’s essential to understand the basic definitions of a couple of key terms, “RMS” and “peak wattage”. Part of the quest to find the best integrated amp under 500 is knowing terminology. The two terms noted above are handy to know when you set out to match the most suitable speakers to your particular amplifier. Here’s what they mean:

The letters RMS stand for “root mean square,” or more specifically, the total amount of continuous electric power that a specific speaker can accommodate. “Peak wattage,” on the other hand, pertains to the one-time burst of maximum power that a speaker can accommodate. Peak wattage only refers to quick bursts while RMS is related to continuous power flow.

For example, if your speaker system is has a rating of “Peak: 90W, RMS: 40W,” that means your system can handle a short burst up to 90 watts but works well with continuous power of 40 watts. When you purchase a sound system, be sure to find out both values for the speakers that are included.

Wireless Connectivity

Wireless connectivity is the wave of the future and is already available for most systems. If you are looking for the best integrated amp under 500, you’ll have plenty of wireless options. The question is why should you aim for an all-wireless audio system? Not only are wireless speakers trendy and fashionable, they offer a simple, clean solution to wire messes that plague so many studios.

Because wireless speakers use either radio or infrared transmitters, you never have to worry about tripping over a wire connector or having a messy studio due to bundles of wires everywhere. Additionally, it’s simple to move a wireless component whenever and wherever you want, without having to deal with the hassle of unplugging and untangling a bunch of wires.

And because these sleek devices have no wires, you’ll never be in danger of tripping and getting injured. Now will your dog or cat be tempted to chew on those stringy little things that look like mouse tails! The human ego being what it is, if you own wireless speakers, you’ll enjoy regaling your friends and visitors with the details of how infrared and digital transmission works. There’s no question that among the best integrated amplifier under 500, the wireless speaker feature is one of the coolest benefits of all.

Should You Get a DAC?

When you’re shopping for the best integrated amp under 500, you’ll wonder whether you should get a digital-to-analog converters, also known as a DAC for short. These efficient pieces of technology morph your digital content directly into analog. That way, your stereo system is able to boost its sound and send that sound through your speakers. Actually, many devices you own already include DACs, namely your blue-ray player, computer, phone, laptop, receiver, clock radios, wireless speakers, and more.

So, what’s the point of acquiring an external DAC? The answer is two-fold, because you need an external DAC to do a couple of things: to eliminate issues with background hissing, or a so-called “noise floor.” Second, an external DAC can clean up various problems with sound quality as it pertains to the conversion process from digital to analog.

Fortunately, you don’t need to be a trained sound engineer to spot these problems. For example, when your playback audio content is quiet but you can still hear a light hissing, you should consider getting an external DAC. The truth is this: external DACs come in handy for lots of audio issues and can only add to your overall sound quality.
