Dolby Laboratories wants to know exactly how viewers respond to its HDR, surround sound, or color palette technologies while watching a movie. So Dolby’s chief scientist and neurophysiologist Poppy Crum has been running 15 to 20 experiments per day in which volunteers sit on a couch attached to brain monitors, heart rate monitors, galvanic skin response sensors, thermal imaging cameras, and lie detectors.

THE VERDICT
Rotel returns to analog amplification for their latest top-of-the-line home theater machine—and the results are golden.
Is the Rotel RAP-1580 the surround receiver that dares not speak its name? In keeping with the two-channel distinction between stereo receivers and integrated amplifiers, Rotel calls it a surround amplified processor because it doesn’t include an AM/FM tuner. But to my mind, the defining trait of a surround receiver is that it combines a surround preamp/processor and a multichannel amp in one box. So I prefer to call this an audiophile receiver. You say tomato... [Editor’s Note: I’d call it a surround amplifier, and I don’t think it’s the last of this type we’ll be seeing...but, whatever.—RS]

THE VERDICT
Revel draws on Harman’s world-class engineering depth to produce immaculate high-end sound—this time, at an extremely reasonable price.
Audiophiles (myself included) often point out that high-end audio is stigmatized compared with other product categories. High-end cars, high-end wine, high-end watches: All attract aficionados who don’t mind paying a stiff premium to get the best of the best. And if an average onlooker ventures an opinion at all, it’s “nice watch!” But when a bleeding-edge speaker or amp takes the stage, the applause of the cognoscenti mixes with heckling from the peanut gallery. High-end audio has long been subject to that extra measure of skepticism.

THE VERDICT
Although not an AVR, Outlaw’s second-generation stereo receiver has an intelligently chosen feature set, bodacious industrial design, and lots of clean power for music lovers on a budget.
One might argue that no single product category has brought vastly improved sound to so many, so fast, as the now-retro stereo receiver. Models poured in during the (mostly) Japanese mass-market audio explosion of the 1970s, when Classic Rock was just rock. My first receiver was a 15-watt-per-channel Pioneer SX-434, but it just as easily could have been a Marantz, Sansui, Kenwood, Luxman, or any of several other storied brands. Today, top-line stereo receivers from the ’70s—their shiny silver faceplates bristling with knobs, buttons, and toggles—command eyebrow-raising prices on eBay and are lovingly restored by vintage hi-fi buffs.
It has been seven years since I last wrote a blog shamelessly promoting my book Practical Home Theater: A Guide to Video and Audio Systems. In fact, I've never told the whole story of why I wrote the book, why I update it every year, and why it's lasted so long—the latest edition, dated 2018, is the 17th. Addicted as I am to numbers divisible by five, I might have waited for the 20th edition. But this blog is long overdue. Think of it as a delayed reaction to the 15th.

THE VERDICT
The Denon HEOS AVR reimagines the black-box receiver as a sleek, shapely, app-driven beauty that leverages the home network to provide wireless sub and surrounds.
Having successfully developed their own wireless ecosystem under the HEOS brand, Denon is using it to reinvent the audio/video receiver. What the company calls the HEOS AVR departs from the black-box norm by offering suave dove-gray aluminum as an optional alternative to the usual black. It isn’t a box, either, or at least not a pure rectangular solid, thanks to a diagonally split, convex front panel. Whereas other A/V receivers wear lots of buttons or conceal them behind a flip-down door, the HEOS AVR has a front panel that’s pointedly devoid of any controls except a large metal volume dial. And in lieu of a front-panel display, it has only a large horizontal LED stripe in the HEOS style for volume and status. This isn’t just another receiver. It’s a deliberate provocation.
Apple will take the wraps off a new version of AirPlay in December as part of the forthcoming iOS 11. AirPlay 2 goes multi-room by including a multiple-speaker function that enables you to pick speakers throughout the home. You might send different songs to different rooms. Multiple users can contribute songs to a playlist. AirPlay 2 can also reach Apple TV devices, thanks to the tvOS 11 update, and it integrates with Apple HomeKit smart home devices.
The triple highlights of the Parasound booth were a new ZoneMaster two-channel amp, new five-channel amp, and new phono preamp, all designed with a knack for combining performance and value.
