A hacker could repurpose a vacuum's Lidar sensor to sense acoustic signals in the environment, vivaldiaudio remotely harvest the Lidar data from the cloud and process the raw signal with deep learning techniques to extract audio information.
In the Q Acoustics speaker, the idea is that the structure (supported by tension) eliminates vibrations going from the speaker down (and the floor up), so you can get great sound out of a floor-stander, without it being the size of the monolith from 2001: A Space Odyssey
So in many ways, Q Acoustics' new Concept 300 speaker is quite restrained: the surreal part is that it comes on a metal tripod that looks like an artist's easel, using ‘Tensegrity' technology first seen in the floating ‘Skylon' tower at the Festival of Britain in 1951.

In the Q Acoustics speaker, the idea is that the structure (supported by tension) eliminates vibrations going from the speaker down (and the floor up), so you can get great sound out of a floor-stander, without it being the size of the monolith from Stanley Kubrick's 2001: A Space Odyssey.
The experts, who call eavesdropping on private conversations 'one of the most common yet detrimental threats to privacy', highlight how a smart device doesn't even need an in-built microphone to snoop on private conversations in the home.
In recent times, many receiver manufacturers have gotten off the "yearly refresh merry-go-round," with only Denon and Yamaha making new models in 2020. Meanwhile, Sony hasn't updated its line since 2017 (and it's still good). Even though older models won't bring you the latest features -- 8K, VRR (Variable Refresh Rate) and so on -- all of the receivers below will offer you the best sound.
As many HDMI inputs as you can afford With most televisions and set-top boxes supporting HDMI, you should buy a receiver that has as many of these inputs and outputs as possible. Front-mounted HDMI ports are kind of like an appendix -- unneeded, because most users don't hot-plug HDMI devices -- making the number of rear inputs what's most important (how else are you going to connect your Blu-ray player, Nintendo Switch, soundbar and all your other devices?). The Sony and Onkyo in this roundup both have six rear-mounted HDMI ports while the Denon and Yamaha go one better 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 be sure you have an extra HDMI cable or two on hand -- these things are like the second sock of a pair in that you can never find them when you need them.
The Yamaha RX-V6A is one of the few receiver models that has debuted since 2019 and, despite a couple of minor dings, offers excellent sound and up-to-date features. The Sony STR-DN1080 also puts in a good showing despite being from 2017. I have rated the Yamaha, Sony and Onkyo as "excellent," with just a little daylight separating their overall CNET ratings. They're all great performers and, as prices fluctuate regularly, if you can find one that's significantly less expensive than the others, go for it -- your speaker system will be well served in any case.
Wi-Fi music streaming Most midrange receivers have onboard Wi-Fi network connectivity for wireless music streaming through your speaker system. There are plenty of standards for wireless streaming services, but the most universal are Spotify Connect, Apple AirPlay 1 and 2 and Google Chromecast built-in. If you're looking to build a multiroom system with a variety of AV systems and speakers with wireless connectivity, these are the three flavors to aim for. The Onkyo and Sony are the only two devices that support all three. The Denon receiver model lacks wireless streaming via Chromecast but ups the ante to AirPlay 2 and the proprietary HEOS system. Yamaha has its own MusicCast in the meantime.
The Yamaha RX-V6A may offer a fresh look at AV receiver design with futuristic edges, but it also doesn't skimp on sound quality. The RX-V6A could make you forget about ever visiting a cinema again, and it's no slouch with music, either. It offers Wi-Fi connectivity, AirPlay 2, Spotify Connect, Bluetooth and Yamaha's MusicCast system for streaming from your devices. It's the most future-proof option of this roundup so far, with 8K pass-through and VRR for compatibility with the .
The Sony STR-DN1080 got our Editors' Choice Award in 2017, and it's still an excellent AV receiver package, albeit getting slightly long in the tooth. Sound quality isn't quite as strong as those of the Denon and Onkyo, but they're all very close. If you want a receiver that offers ease of use and integrates both AirPlay (but not AirPlay 2) and Google Chromecast built-in wireless streaming, this is a great AV receiver option. It even uses virtual speaker relocation technology to optimize sound in the room where you set it up. Don't pay full price, though -- it has been on sale in the past for between $400 and $500.
