Audio and video receivers are known to be very complex, containing a wide range of confusing features and technical specifications. (For example, what is 4K/120Hz anyway?) However, what are the things that really matter to you when purchasing a new model? I will summarize the most important ones here.
Since most TVs and receivers support HDMI, you should buy a receiver that has as many HDMI input and output ports as possible. The front-mounted HDMI ports are like a human appendage—they’re unnecessary, because most users don’t connect HDMI devices—making the number of rear inputs all the more important. (How else would you connect your Roku device, Blu-ray player, Nintendo Switch And all your other devices?) The Onkyo TX-NR6100 and Denon AVR-S970H have six rear-mounted HDMI inputs, while the Yamaha RX-V6A tops out one with seven. If you want to connect two different displays — a TV and a projector, for example — all but the Yamaha offer a second HDMI output. You should also make sure you have an extra HDMI cable or two on hand – these things are like a second sock for a pair as you can never find them when you need them.
Most receivers in the $500 and above price range include Dolby Atmos Ability and DTS:XHowever, the impact of these formats on home theater viewing may be subtle, or non-existent, in most films. In other words, don’t worry about missing out on these arrangements by not installing a speaker or two pointing at the ceiling. Mounting your rear surround speakers high on the wall will get you halfway in terms of quality and immersive sound.
Most mid-range receivers have built-in Wi-Fi connectivity Wireless music streaming via your speaker system. There are many standards for wireless streaming services, but the most universal standards are: Spotify Connectapple Broadcast And Google Cast. If you’re looking to create a multi-room system that includes a variety of AV systems and speakers with wireless connectivity, these are the three flavors you should aim for. Onkyo and Sony are the only two devices that support these three devices. The Denon receiver model lacks Google wireless streaming but ups the ante Broadcast 2 And the special HEOS system. Meanwhile, Yamaha has its own MusicCast system.
