The Good The Sony STR-DN840 is extraordinarily well-featured for the price, with its built-in Wi-Fi, Bluetooth, and AirPlay, allowing for convenient wireless streaming from nearly any mobile device. There are six HDMI inputs, which is enough to cover almost every home theater. And its sound quality is solid, although not a standout.

The Bad No MHL-compatible inputs or true second-zone audio support.

The Bottom Line The Sony STR-DN840 is by far the best AV receiver value of the year, offering tons of wireless connectivity and six HDMI inputs for well under $500.

The Sony STR-DN840 ($420 street) is by far the best AV receiver value of 2013. It starts with its outstanding wireless features, serving up built-in Wi-Fi, AirPlay, and Bluetooth, which no other receiver at this price can match. That allows Sony to nail the instant gratification experience: select the STR-DN840 via Bluetooth or AirPlay from your smartphone or tablet, and the receiver automatically powers on and flips to the correct input. In other words, you can be streaming to your big speakers in seconds. If your music collection revolves around your mobile devices, you're going to love the STR-DN840.

The rest of the STR-DN840 is solid, too, with six HDMI inputs and solid sound quality. It may be slightly pricier than some of its competitors (such as the $400 Pioneer VSX-823-K), but the benefits are worth it, especially for a component you're likely to hold onto for five years or more.

There are some other worthwhile alternatives to consider, mainly the slim Marantz NR1403, the turntable-friendly Onkyo TX-NR626, and Sony's step-up STR-DN1040, which adds some bells and whistles, including an impressive graphical user interface. But for most buyers the STR-DN840 hits the sweet spot of features, performance, and pricing, which is why it earns CNET's Editors' Choice Award for the category.

Design: Big, but minimal
The Sony STR-DN840 basically looks like a traditional AV receiver: it's a big, black metal box. Still, it manages to look slightly better than most, with some of Sony's design talents clearly showing through on its tastefully minimal front panel. The STR-DN840 doesn't have nearly the refinement of the Marantz NR1403, but it won't look too bad in your home theater cabinet, either.

The STR-DN840's remote is better than the ones that come with most AV receivers, although it's still a bit of a cluttered mess. The bright white input buttons are distinct and easy to read, and the directional pad nicely falls right under your thumb. On the other hand, there are still just way too many unneeded buttons, not to mention secondary functions written in pink above some buttons, only adding to the confusion. There are also two rockers at the bottom that look like volume controls; one of them actually cycles through the available "sound fields," which is a dubious feature that certainly doesn't deserve dual-billing with the all-important volume rocker. If you're investing this much in your home theater system, you'd be wise to invest in a universal remote.

Features: All the wireless you could want
The STR-DN840 is hands-down the most fully featured receiver at this price.

That starts with six HDMI inputs on the back panel, which matches the most you'll find short of stepping up to Sony's STR-DN1040, which includes eight. There's no MHL-compatibility, like you'll find on some competitors (such as the Onkyo TX-NR626, Yamaha RX-V475, Pioneer VSX-823-K), but that's not much of a loss unless you were planning to use Roku's Streaming Stick. The STR-DN840 has a fair assortment of legacy connections, including three digital audio inputs (two optical, one coaxial) and four analog audio inputs. There aren't any component video connections at all, but that's fine by us now that most devices use HDMI.

What's most impressive is the STR-DN840's wireless capabilities. There's built-in Wi-Fi, AirPlay, and Bluetooth, which makes it a truly standout for receivers under $600. It's a potent combination, particularly the flexibility to wirelessly stream audio from nearly any smartphone or tablet. Bluetooth and AirPlay work with any app on your mobile devices, so you can easy load up, say, Spotify, stream right to your receiver, and maintain playback control on your phone.

The STR-DN840 is also DLNA compliant and supports several integrated streaming services, including Pandora, Slacker, Sony Music Unlimited, and Internet radio, but you're best served streaming from a mobile device if you can, since AV receivers aren't great media streamers themselves.

Sony is also smart about how the wireless features are implemented. Turning on "network standby" lets you "wake up" the receiver simply by selecting it as your source on your mobile devices using AirPlay or Bluetooth. That means you can start listening to music on your home stereo without picking up any remote other than your smartphone or tablet. It's incredibly convenient and feels like the way all AV receivers should work with modern gadgets.

The rest of the features are less important for mainstream buyers. The STR-DN840 is a 7.2-channel receiver, but most buyers won't need the extra functionality that enables: surround back channels, dual subwoofer capabilities, and Dolby Pro Logic IIz "height" channels. There's no analog video upconversion, but again, that's less of a concern now that most modern devices use HDMI. It is worth pointing out that despite supporting seven channels, the STR-DN840 does not have true second-zone functionality, so you'll need to look elsewhere if you have a two-room setup.

Setup: Quick, but manual is better
The STR-DN840 uses Sony's Digital Cinema Auto Calibration (DCAC) automatic speaker calibration system. The owner's manual recommends turning your subwoofer's volume control to the midpoint, and if the sub has a crossover control knob, setting it to the highest number setting -- a good start. The onscreen display guides you through choosing the correct "SP Pattern" (speaker pattern) for you home theater, which in plain English means how many speakers are in your home theater, and if you're bi-amping the front speakers, or using height speakers, etc. Next, you plug in the supplied calibration microphone and the fully automatic process takes about a minute to complete.
