In this article, we discuss the best AV receivers for music listening. We provide detailed reviews and comparisons of various models, considering factors such as sound quality, connectivity options, and ease of use to help you make an informed decision when choosing an AV receiver for your music needs.
The first thing that comes to mind when talking about AV receivers is probably surround sound. However, AV receivers can also be used as a replacement for an integrated stereo amplifier. In other words, they can also be used for music, not just movies. But not all AV receivers sound equally good with movies and with music. That’s why we are here. Our article about 8 best AV receivers for music in 2024 is here to help you find the perfect receiver for your speaker system. We will talk about things you should pay attention to when buying an AV receiver for music, discuss the prices, and present to you some nice suggestions.
Things to Look for When Buying an AV Receiver for Music
When buying an AV receiver for music, it is essential to consider factors such as sound quality, connectivity options, power output, channel configurations and features like Wi-Fi or Bluetooth. Here is an in-depth guide to help you make an informed decision when purchasing an AV receiver for music listening.
Well, looking for an AV receiver for music is not much different from looking for any AV receiver. After all, their primary purpose is to drive your surround sound system. Music reproduction is also important, but it’s still secondary. If you need the best possible amplification and audiophile-grade equipment for your high-end stereo speaker system, then you should probably think about buying a dedicated power amp and preamp. And maybe even a dedicated DAC. As far as AV receivers are concerned, you’re getting everything in one package (or in some cases – in two separate units).
So, the first thing to pay attention to is the number and type of inputs/outputs. As far as inputs are concerned, you need enough HDMI inputs to connect your video equipment and enough analog and digital audio inputs for your audio equipment. If you have a turntable, you should also look for an AV receiver with a phono stage.
When it comes to outputs, you should be looking for something that matches your speaker setup and gives you flexibility when it comes to upgrades. If you have a new TV, you should be looking for a receiver with HDMI ARC support. Some receivers also have dedicated outputs for one or two independent speaker pairs located in other rooms (multizone audio). Another thing that may come in handy are preamp outputs for all the channels (especially for the front left and right). If a receiver has those pre-outputs, you can buy a dedicated power amp in the future and run the interconnects from two of the receiver’s preamp outputs to the stereo amp and get a much better stereo performance when playing music.

Finally, look for a receiver that has a high enough power output. And preferably, go for a receiver with a Class A/B amplification. Many affordable AV receivers have built-in Class-D amps (because Class-D amps are cheaper). Class A/B amps are less efficient than the Class-D amps but are better when it comes to sound fidelity and transparency. So, when looking for an AV receiver for music, you should pay a bit more attention to the sonic characteristics of the receiver.
If you’re interested in additional features, look for a receiver with Bluetooth and Wi-Fi connectivity, with internet radio, Alexa, Chromecast, or Airplay support, etc.
After long research and testing, we’ve gathered our favorites and made the following selection of 8 best AV receivers for music. We tried hard to make a comprehensive list and to include both – budget-friendly and high-end options. Hopefully, this list will help you find the perfect receiver for your setup.
8 Best AV Receivers for Music
1. Best Overall – Yamaha AVENTAGE CX-A5200 + Yamaha AVENTAGE MX-A5200BL
Having separate units for every purpose is the preferred way if you’re an audiophile. That’s why we decided to start our list of 8 best AV receivers for music in 2024 with a combo. It’s Yamaha’s CX-A5200 surround sound processor (AV preamp) paired with Yamaha’s MX-A5200BL multi-channel power amp. In this combo, the preamp is in charge of receiving and processing the signal, while the amplification is done by the separate unit (MX-A5200BL). This way, you will get a higher (and cleaner) power output, with much less noise, lower THD, and higher fidelity and sound transparency. It’s a perfect combo for both – surround sound and music reproduction.
Things we like
The preamp unit (CX-A5200) looks like a regular AV receiver with controls on the front and inputs/outputs on the back. The front panel looks exactly like the panel of some Yamaha Aventage AV receivers (RX-A1080, A2080, A3080). However, the big difference is that CX-A5200 doesn’t have any powered speaker outputs. Instead, it has 11 balanced XLR preamp outputs that connect to 11 XLR inputs on the MX-A5200BL. It also has 11 unbalanced RCA pre-outputs.
For sound optimization and calibration, you can use Yamaha’s famous YPAO calibration tool. It truly gives great results and makes a huge difference.
When it comes to inputs, you have 7 HDMI inputs and 3 outputs. All HDMI inputs support 4K UHD pass-through and 3D video. Furthermore, all 10 HDMI ports are compliant with HDCP 2.2 and support all the latest image standards (HDR10, HLG, Dolby Vision, BT.2021).
The unit also houses 4 composite video inputs, 2 component inputs, three coaxial, three optical audio inputs, 8 RCA inputs, and one phono input. On the front, you have a headphone output, RCA input, USB port, and YPAO mic connector.
As far as additional features are concerned, CX-A5200 features Bluetooth connectivity (V4.2 with AAC and SBC support) and dual-band wi-fi connectivity (2.4/5GHz). It also supports Airplay2 and features MusicCast. Thanks to MusicCast, the unit can be seamlessly integrated with other multiroom products (speakers, soundbars, and receivers) featuring MultiCast.
What guarantees great surround sound performance is the so-called Surround:AI processor built inside the DSP chip. This processor analyzes all the scenes in real-time and adjusts the sound reproduction constantly, creating a great sense of realism.
When it comes to music processing and digital-to-analog conversion, CX-A5200 features dual Sabre Pro Premier DAC chips (ES9026PRO) that enable 32bit/384kHz conversion. The unit can play FLAC, ALAC, WAV, AIFF, and DSD audio files (up to DSD256).
Yamaha AVENTAGE MX-A5200BL multi-channel power amp has a much cleaner look. On the front, there’s just the power button and A/B speaker selectors. On the back, there are 11 XLR balanced inputs, 11 unbalanced RCA inputs, and 11 speaker terminals arranged in two sections (R and L). The RMS power output with two 8Ω channels driven is rated at 150W (20Hz-20kHz, 0.06% THD). With bridged connection and two 8Ω loads, the RMS power output is rated at 200W (20Hz-20kHz, 0.06% THD).

Things to Look Out For in a Good AV Receiver
Now we explore the key factors to consider when selecting a good AV receiver. From sound quality to connectivity options, we will discuss the essential features that make an AV receiver suitable for delivering a great audio experience.
An Audio-Video (AV) receiver acts as the central hub for your home entertainment system, handling audio processing and video pass-through. If you're in the market for one, here are some essential factors to consider:
1. Number of Channels
The number of channels in an AV receiver determines how many speakers it can support. If you plan to set up a simple stereo or a 5.1 surround sound system, a receiver with five channels will suffice. But if you aim for a 7.1, 9.2, or even an 11.2 Dolby Atmos setup, ensure the receiver has enough channels to accommodate.
2. Power Output
The power output of an AV receiver, measured in watts, signifies how loud the system can get. More power can provide better sound quality at higher volumes, but remember that very high-power receivers may require compatible, high-quality speakers to perform optimally.
3. HDMI Inputs
The number of HDMI inputs is crucial because it determines how many devices (like gaming consoles, Blu-ray players, or streaming devices) you can connect to the receiver. Always look for a receiver that has more HDMI inputs than you currently need. It will help accommodate future upgrades.
4. Support for Latest Audio and Video Formats
Your AV receiver should be capable of decoding the latest audio formats like Dolby Atmos and DTS:X. Also, look for video support for 4K, HDR, and HDMI 2.1, which are becoming standard in modern home entertainment.
5. Network Connectivity
Modern AV receivers often come with network connectivity options, like Wi-Fi and Ethernet. This feature allows for network streaming and integration with your smart home devices.
6. Calibration System
A good AV receiver will include an automatic speaker calibration system. This feature adjusts the sound output based on the specific acoustics of your room, ensuring the best possible sound quality.
7. User Interface:
The receiver should have an easy-to-understand and navigate user interface. This will make setup and daily operation a breeze.
8. Brand Reputation and Reviews
Lastly, look into the brand's reputation and customer reviews. Brands with a history of quality products and strong customer support are often safer bets. Reviews can provide insights into real-world performance and potential issues.
FAQs
A: There are so many great AV receivers with all kinds of features, connections, and power outputs. The price also varies a lot. All these things make it practically impossible to select just one receiver. That’s one of the reasons we made our list of best 8 AV receivers for music in 2024. Check it out and find a receiver that meets your requirements and fits the budget.
A: Well, there are a few names that come to mind. Some of the most reputable brands when it comes to receivers are Marantz, Pioneer, Denon, Onkyo, Yamaha, Arcam, NAD, etc. The first four brands (+ Integra) are now part of the same audio company called Sound United and they often share technologies, so you can usually find the same (or at least similar) features on similarly priced AV receivers coming from these manufacturers.
A: AV receivers have a crucial effect on the audio quality. After all, they are responsible for receiving the signal from all the sources, for all the audio signal processing, for converting all the digital signals to analog, and finally, they are responsible for the amplification. All those things determine the quality of the sound. So, yeah, AV receivers are very important for the audio quality.
A: As discussed in one of the previous answers, Marantz and Denon are now part of the same company and use the same technological solutions (like auto-calibration tools, apps, etc.). The same-priced receivers from Denon and Marantz have similar features and number of connections but there are some subtle differences in sound reproduction – Denon is a bit brighter while the Marantz receivers sound warmer. In the end, it all depends on your taste in sound.
A: We have discussed this in the introduction, so here's a short recap. First, set your budget limits. Second, determine how many HDMI and other inputs you need to connect all the existing and maybe some future sources you want to buy. Third, look for the receiver with enough speaker outputs for all the home theater speakers you want to connect and check if it has enough power to drive all the speakers. Finally, look for additional features you find important (Bluetooth, wi-fi, app, Chromecast, Airplay, internet radio, etc.).
A: In general, the answer is yes. Pricier receivers enable cleaner signal processing, have higher power output and sound better. However, the quality of the sources and of the original audio coming to your receiver, as well as the quality of the speakers, are also very important. Having poor-quality speakers connected to a high-end AV receiver is absolutely meaningless.
A: Yes. An AV receiver can be used as a power amp. One of the purposes of a receiver is to amplify the audio signal and send it to speakers, just like a power amp.
