Well, my task is to hold your hand and we will tiptoe together through the minefield that is the home theater receiver. You never know, you may even enjoy it!

First, I will explain a few of the most important features that you should be looking out for. Next, I will review a few of my favorites that you might want to consider. And finally, I will give you a brief buying guide and answer some frequently asked questions.

Best AV Receivers 2017

What Is An AV Receiver?

An AV receiver acts a central hub in a home theater system. It is the 'brain' of your whole setup.

A home theater receiver simplifies the connection of many devices to your speaker system and TV/projector.

It allows you to connect, and switch between, several playback devices. Blu-ray players, games consoles, video cameras, CD players - even content from your mobile devices.

An AV receiver is the amplifier that powers your speaker system. It also sends the picture to your TV or projector.

Being able to connect all these different devices into one unit makes it much easier to set up and operate multiple audio-visual sources.

Different Features Of AV Receivers

Each manufacturer of AV receiver has so many different models, it can make it a real headache trying to decide which one to buy.

One thing you should realize is that all brands release a series of surround sound receivers at different price points. You may see several receivers with different model numbers, but they are probably very similar. They are just part of the same series with an increasing number of features as the price rises.

I will now run through some of the main differences that you will come across. This should make it clearer to decide which is important for you.

Number Of Channels

AV receivers are designed to support different surround sound speaker layouts. So, you need to buy a receiver which allows for the type of speaker configuration you want.

The one you choose may just come down to how much you want to spend. After all, more speakers = more money. Or simply how much space you have in your room for all those speakers.

The standard surround sound speaker layout is 5.1. This means three speakers at the front – center, front left and front right. Then, two rear surround speakers on the left and right.

The following table summarizes the common surround sound speaker layouts:

The .1 refers to a subwoofer, which is a speaker that is designed to play back very low bass frequencies. This can add fantastic weight and rumble to a movie soundtrack. And really annoy the neighbors!

You can find more details in the guide to surround sound speaker layouts.

Dolby Atmos®, DTS:X™ And Auro-3 D

A new development is the introduction of Dolby Atmos and DTS:X. These are object-based soundtracks. Sound effects can be placed using a combination of height, front/back and left/right speakers.

There is another option when it comes to 3D surround sound, and that is Auro-3D. Developed by Auro Technologies, this is another possible surround sound format which you may find with an AV receiver. Some of the top end models provide this as an optional add-on.

You will see many of the newer AV receivers supporting these audio formats. Of course, if you need this depends if you are going to the expense of adding the extra speakers to your room. Or if you have any movies that provide this format on the disc.

For DTS:X, you can use your existing 5.1 or 7.1 surround sound speaker system. You don’t need to worry about installing extra speakers.

For Dolby Atmos, you will need to add a minimum of two extra height speakers to your 5.1 or 7.1 setup - up to a maximum of 64! The Dolby Atmos speaker configuration with two extra height speakers is written as 5.1.2. Or 7.1.2 for the seven channel version.

Klipsch RP-140SA speakers

The extra speakers for Dolby Atmos can either be in-ceiling speakers, or special elevation speakers. An example of this is the Klipsch RP-140SA speaker pictured above. Elevation speakers are easier to install as you just place them on top of your existing floor standing or bookshelf speakers.

Auro-3D builds on a standard 5.1 or 7.1 sound system and adds a height and overhead layer. The basic setup is a 9.1 speaker configuration with extra height speakers at the front and rear.

There is also a 10.1 version which adds a single ‘Voice of God’ speaker directly above the listening position.

If you really don’t have enough speakers at this point, there are further options for 11.1 and 13.1 layouts!

Number Of Connections

One of the best things about an AV receiver is the sheer number of connections it has on the back. Now, initially, this may just make it look like something you might find on the console of a spaceship. But the advantage is you can easily connect a wide range of different device into your home theater system.

However, the number and type of connections will vary between models. When choosing a model to buy, it is important to think about all the different devices you will want to add to your setup. And what type of connections they require.

One of the most important connection specifications is the number of HDMI inputs and outputs.

These days, most modern AV equipment will use HDMI to send the signal – both picture and audio. Therefore, look at the number of HDMI inputs on the AV receiver.

7 HDMI Inputs & 2 HDMI Outputs on the rear of an AV receiver

It will usually be listed something like – 7/2. This example means there are 7 HDMI inputs and 2 HDMI outputs.

Therefore, you can connect up to seven external devices into the receiver via HDMI.

As for HDMI outputs, most people only require one - to their TV or projector. However, some models offer two (or more) which can be useful if you want to send the picture to another display or projector at the same time.

Apart from HDMI connections, think about all the other devices you may want to connect – and what type of connections they use. Games console? Video camera? CD player?

Does the receiver offer all the connection types you need? Maybe allow for a couple of extra ones for future purchases?

Network AV Receivers

Another feature you might want to look out for is network connectivity. A fairly recent innovation, a network AV receiver will have an ethernet connection allowing you to connect it to your home network.

Ethernet Connection on AV Receiver

This can allow various Internet-based features like streaming of online music and radio services. Such as Spotify, Pandora, Amazon Music and Napster. You may also be able to stream your own music collection over the network using DLNA.

The best home theater receivers will also be able to connect via WiFi, Bluetooth or AirPlay. This can also allow for streaming music from the network – or sending video or music to your system via a mobile device such as your phone.

You could also connect wirelessly to external speakers around your home.

If this sounds useful, then make sure the receiver you buy has the right network connectivity.

Power Ratings

Many models of AV amplifiers will show the power rating of the device. Put very simply, this means how loud you can make it in the room.

As a rule, the more expensive models will have more power.

However, it can get very tricky when trying to compare the power ratings of two different AV receivers. There are different ways of measuring the power an amplifier can output. You must, therefore, be sure you are comparing like with like.

The bigger number isn’t always better!

You must compare power numbers that are rated using similar tests. Otherwise, it doesn’t mean anything. The common variables are:

  • the number of channels being driven – e.g. 2 channels
  • the frequency of the test signal – e.g. 20Hz-20kHz
  • the impedance of the speaker being driven – e.g. 8 ohms
  • the recorded level of distortion. Less than 1% is acceptable – e.g. 0.06% THD

Also, you should be aware that a higher power rating doesn’t mean that the amplifier will be that much louder than one with a lower rating. And most people won’t need the extra volume anyway.

I have written an article on understanding amplifier and receiver power ratings if you want more detail on this.

Generally, power ratings will range from around 50 to 200 watts. 50 to 100 watts will be plenty for most average-sized rooms. However, there’s no problem buying one with more power if you want. Just make sure your speakers will be able to handle the extra power if you plan on turning it up really loud.

The Best AV Receiver Brands

There are several great AV receiver brands. Whilst I’m not going to list them all, here is a quick summary of some of my favorites.

Denon

Denon is a Japanese electronics company formed in the early 1900’s. They began producing hi-fi audio components in 1971 and now specialize in home theater and wireless audio products.

They have two main ranges of AV receivers:

  • AVR-X Series: caters for the top-end of the market, with high-quality products at a range of prices.
  • AVR-S Series: has more modest prices, but still provide excellent value for money and plenty of features.

Marantz

Marantz was originally founded in New York in the 1950’s when the founder produced his first audio product – a preamp. After many years of success in the hi-fi audio market, the company was sold to Marantz Japan in 2001. They are now a sister company to Denon.

They have a smaller range of AV receivers than some of their competitors but are well-regarded.

  • SR Series: a range of surround AV receivers.
  • NR Series: a range of network AV receivers with internet-based features.

Onkyo

Onkyo has been producing consumer electronics since 1946. They are a Japanese company and specialize in audio products and home theater equipment. Their range includes hi-fi components, personal audio technology and various speaker systems.

Onkyo has been producing popular AV receivers for many years. Their range of receivers include:

  • RZ Series: premium range. Provides a superior audio performance for music and movies.
  • NR Series: mid-range. Network AV receivers.
  • SR Series: value range. Surround AV receivers.

Pioneer

Based in Tokyo, Japan, Pioneer have a long history of producing popular AV products. Although they stopped making televisions in 2009, they still produce many products for the home AV market.

In 2014, Pioneer sold their home AV business to Onkyo, and so they are now sister companies. However, Pioneer still releases products under their own brand name.

Their premium range of AV receivers is labeled the Elite Series. The aim is to produce high-end products aimed at audiophiles and sound purists. Within this range, Pioneer release receivers at two different price points:

  • Elite SC Series: this is top-of-the-range.
  • Elite VSX Series: network AV receivers at a slightly lower price point.
  • VSX Series: not part of the Elite series. Slightly fewer features and aimed at the lower-end of the market.

It’s slightly confusing, but the Elite VSX models are labeled VSX-LXxxx, and the non-Elite VSX models are labeled VSX-xxx (without the LX).


Sony

Sony is one of the most well-known home electronics brands in the world. Among its many areas of business, this Japanese company produces many popular products in the home AV market.

They offer three main ranges of AV receivers:

  • Z Series: top-of-the-range for the custom installation market.
  • STR-DN Series: network receivers aimed at a more mainstream audience.
  • STR-DH Series: value range of AV receivers.

Yamaha

Yamaha is a Japanese company that has been producing a wide range of products for over 100 years. They have a strong reputation in a diverse range of markets. None more so than in musical instruments, professional audio and audio-visual technology.

Yamaha produces some of the best surround sound receivers and has a range of models to suit all needs and budgets.

  • Adventage Series: premium range. Studio grade sound and superb video performance.
  • RX-V Series: mid-range. Engineered to sound great and offer a range of home theater features.
  • RX-S Series: mid-range. Slim and compact AV receivers.
  • TSR Series: mid-range. High-end audio converters and top audio performance.

Top 5 AV Receivers Review

In the table at the top of the page, I selected my top 10 AV receivers currently in 2017. There are so many to choose from, that you’ve got to start somewhere!

While it would be easy to just pick the most expensive model from each manufacturer, I have tried to keep in mind value-for-money too. Therefore, you will find a range of AV receivers from different price brackets. Hopefully, there should be something for everyone in the list.

If you find yourself getting lost in the sea of acronyms (hard to avoid I’m afraid), I’ve explained some of them at the bottom of the page - AV receiver acronyms.

Now, I’ll take a closer look at the top 5 AV receivers, and after that will highlight the important features of the next 5.

AV Receiver Buying Guide

I’ve already been through some of the important areas to look out for when you are looking for the best home theater receiver.  But now, let's tie it all together.

Firstly, you might find it useful to familiarize yourself with the back of an AV receiver.

Let me summarize the important points again, and I will mention a couple of extra things to think about:

  • Power: you can only compare the power of two different AV amplifiers if they are tested using the same variables. In this guide, I have chosen 8 ohms, 20 Hz - 20 kHz and with 2 channels driven as the baseline. There are different tests. Don’t get too worried about the power. 50 – 100 watts should be fine for most rooms. Doubling the power only increases the sound level by 3 dB (10 dB is ‘twice as loud’).
  • Speaker Ratings: is the AV receiver suitable for the speakers you want to use? Most modern home theater equipment will play nicely with each other. You probably don’t need to worry. But if you have some exotic speakers, you might want to check this. If you don’t know what I’m talking about, here’s my guide to matching amplifiers and speakers.
  • Connections: make sure the AV receiver you buy has all the right connections types for all your equipment. HDMI is the most common connection type these days, so are there enough HDMI inputs? If you want to output the picture to another screen or projector at the same time, you will need at least 2 HDMI outputs.
  • Network: many modern AV receivers are network-enabled. However, you may be able to save money if you don’t need this. A network connection can enable you to stream content from your network or from the internet. The most common ways of connecting are via ethernet and W-Fi. But there are also Bluetooth, AirPlay and Chromecast. Choose a receiver with the ones that suit you best.
  • Number of Channels: the most common surround sound layouts are 5.1 and 7.1. All modern AV receivers will support these. If you want to go further and try 9.1 or 11.1, then pick a receiver that supports this.
  • 3D and Object-based Audio: if you want to experience enhanced surround sound, look for an AV receiver that supports the latest 3D audio technologies. Dolby Atmos, DTS:X or Auro-3D. Dolby Atmos and Auro-3D require the addition of two extra height speakers (as a minimum). DTS:X can use your existing 5.1/7.1 setup.
  • Listening Modes and Surround Sound Formats: there are several different surround sound audio formats on a Blu-day disc. We’ve discussed Dolby Atmos and DTS:X. However, there is LPCM, Dolby TrueHD, DTS-HD Master Audio and much more. Some may be supported by your AV receiver and some may not. To learn more, see the article on Dolby and DTS audio formats. Also, learn more about AV receiver listening modes here.
  • Zones: many receivers will have additional zone connections to allow you to send video and/or audio into different rooms. Some zones will be audio only. Some zones may need an extra amplifier in the other room. It varies a great deal. First, decide what you want to do, and then find a receiver that does it.
  • Multi-room wireless speakers: many newer models will have their own multi-room wireless speaker systems. For example, Yamaha has their MusicCast system, and Denon uses their HEOS wireless system. If you want this, go with a brand that provides multi-room wireless speakers as an extension to the AV receiver. This can be a good alternative to the more established wireless multi-room speaker systems such as the Sonos Play or the Bose SoundTouch.
  • Choose the Right Series: all AV receiver manufacturers have a range of products at different price points. They will have a premium series with high-end components and all the latest features. They will also have a mid-range and value range set of receivers. These receivers can still give great value for money and fantastic quality. For example, you can see my guide to the best AV receiver under $500.

Conclusion

Well, there we have it. Phew, that is a lot of information to take in.

If you are new to the field of home theater, then it can appear impossible to know where to start. Or what you should be looking out for.

Even when you do about this stuff it can get confusing!

However, don’t lose sight of the end goal. Having great audio in your room is a fantastic way of experiencing movies and music in your room. You won’t regret it.

Hopefully, this guide will help you find the best AV receivers in 2017. Buy a good one, and it will last for years to come.

Frequently Asked Questions: AV Receivers

What Is An Integrated Amplifier?

All playback devices, like CD or DVD players, output the audio at a low level. This is called line level. This is not strong enough to power a set of speakers directly, therefore we need to boost it by using an amplifier.

There are two stages to this process:

  1. There is a preamp (preamplifier) which receives the audio and makes it louder. The preamp will usually allow the connection of several different sources and will have a volume control to vary how loud the sound is output. 
  2. After the preamp, the signal is passed to a power amp which amplifies the audio even more and sends it to a connected set of speakers.

An integrated amplifier has the electronics for both the preamp and the power amp in a single box.

An AV receiver is an integrated amplifier because it receives input devices, and then powers our speakers. All in one box.

Some more advanced audio systems will use two separate boxes – a dedicated preamp and power amp.

AV Receiver vs Amplifier - What Is A Receiver?

So, now we understand that an AV receiver is basically an integrated amplifier, why is it called a receiver? Quite simply, a receiver is an integrated amplifier that also has a tuner to receive AM/FM radio signals.

Preamp + power amp + tuner = receiver.

Technically, if the device doesn’t have a tuner, it should be called an AV amplifier. Although the term AV receiver is often used regardless.

Stereo Receiver vs Surround Sound Receiver

Most people who want a home theater sound system, usually think about surround sound with several speakers around the room. This is especially great for movie soundtracks. However, you can still get great movie audio in your room by using stereo speakers.

If you were happy with stereo only, then you only need to buy a stereo receiver which powers just two speakers.

AV receivers will support multiple speakers and play surround sound soundtracks from Blu-ray or DVD players. An AV receiver is often referred to by many different names such as a surround sound amplifier or simply a home theater receiver. They all essentially refer to the same thing.

Go here to see the difference between hooking up a stereo and surround sound receiver.

Although an AV receiver supports surround sound, we can also use it to play back stereo sound sources too – like CDs. However, a dedicated stereo amplifier will usually provide better hi-fi sound than an AV receiver. You would need to buy a high-end AV receiver if you also wanted it to get near the quality of a stereo receiver.

Many home users will have an AV receiver for movie audio, and use a dedicated stereo amplifier for listening to music.

What Are Upconverting And Upscaling?

One important thing to think about when looking at AV receivers is the ability of the device to upconvert or upscale a video signal.

These are two different things.

By upconverting I mean, can it receive one type of video input (e.g. analog component video) and output it as another (e.g. digital HDMI)?

The AV receiver will need to able to do this if I am connecting a DVD player into it using component connections. And expecting it to output via HDMI to my TV screen.

If it can't upconvert, I will have to send the component video signal directly to the display via a component connection. This means more cables to the display.

It may not be the end of the world if the AV receiver cannot upconvert various types of inputs. Just be aware that this may be a limitation if you are hoping to keep the cabling of your system as simple as possible.

For upscaling, I am talking about converting lower resolution video into a higher resolution i.e. from 576i PAL to my 1080p screen. Or from 1080p to my 4K Ultra HD TV.

This process is performed by a video scaler.

If the receiver doesn't upscale, then this job could be done by the Blu-ray/DVD player or the screen itself. So, it may not be something you need in your AV receiver.

Most modern TV screens have pretty good scalers built-in. So, it will automatically upscale a lower resolution image to display on the screen.

Acronym Central

If you love an acronym, you will have a great time researching AV receivers! However, if all those complicated terms bring you out in a cold sweat, let me help a little by summarizing some of the common ones you will come across:

  • HDR: stands for High Dynamic Range. A technique that increases the dynamic range of an image. Darker blacks. Brighter whites. More colors. This will make a picture look more life-like. Your AV receiver will need to support HDR to pass this type of content to your HDR-compatible TV.
  • Dolby Vision™: a variation of HDR developed by Dolby. The main advantage over standard HDR is that it can transmit scene-by-scene data to the TV screen on how it should display. It can also adjust to the capabilities of each TV. Dolby Vision can be added via a firmware update, so you may find your current hardware can be updated.
  • BT.2020: the 10-bit color standard incorporated into the Ultra HD specification. It enables the display of more colors. Your AV receiver will need to support BT.2020 to pass this type of content to your 4K-compatible TV.
  • HDCP 2.2: to play encrypted 4K content, every device in the playback chain needs to support this copy protection standard. If your Ultra HD Blu-ray player and your TV support HDCP 2.2, but your 4K AV receiver doesn’t, then the content won’t play.
  • HDMI ARC: Audio Return Channel. Some HDMI ports may be labeled as ARC (on the TV and the AV receiver). This means you can send audio from the TV back to the AV receiver. This can simplify your connections. You don’t need to connect a separate optical cable if you want to hear the audio that is generated within the TV e.g. a Netflix app. This is also useful if your TV doesn’t have a digital audio out.
  • DLNA: Stands for Digital Living Network Alliance. A trade organisation of over 250 companies. They aim to create a set of standards to make it easier to use and share digital music, video and photos. A 'DLNA-certified' device will be able to share data with other DLNA devices on the same network. A standard setup would have a server which stores the digital media - like a PC or NAS drive. Then, clients will be able to 'see' the server on the network and be able to play back the files. A client might be a TV, laptop or an AV receiver.
