Recently, on seeing the Apple Music app on my phone, a friend’s kid smirked. The problem? Apparently, I’d decided to spend my money on uncool Apple Music rather than on cool Spotify. Lame!

In last month’s editorial, I explained my decision to sit out this year’s Consumer Electronics Show. Turns out my absence didn’t make a difference: When Laundroid, the artificial intelligence-powered laundry-folding machine, was introduced at the Las Vegas Convention Center, plenty of news outlets were onsite to pick up the slack. I can’t say I regret missing CES 2018, but I do wish I’d been around to see the LVCC’s lights go out for two hours on opening day. An electronics show with no electricity -- now that’s news.

Careful listening to recordings is by its nature a solitary experience. That’s why audiophiles have a rep for being loners -- you can’t fully soak in the nuances of great music unless you’re focused on listening, and that requires both concentration and a degree of isolation.

I made my first trip to the Consumer Electronics Show, held each January in Las Vegas, in 1994. Most high-end gear was then exhibited in the Sahara hotel, a now-defunct icon of the Rat Pack era, where they butted up against a different home-entertainment event: the Adult Entertainment Expo. While the combination of consumer electronics and porn was an uncomfortable one -- it came undone in 1998, when the porn-video industry broke away to establish its own, independent show -- the high-end audio scene at that moment seemed to have a bigger worry: home theater.

The 2017 edition of the Custom Electronic Design & Installation Association’s annual exposition, formerly called the CEDIA Expo but now simply CEDIA, took place in early September at the San Diego Convention Center. Though CEDIA is ground zero for networked audio, most of the products displayed this year were in-wall and in-ceiling speakers connected to multizone amps operated by proprietary, keypad-controlled, home-automation systems. In other words, CEDIA was packed with gear designed to be heard, not seen -- products mainly of interest to custom-installation professionals. Since the dawn of Sonos, however, a stream of consumer-oriented products have popped up amid the aisles of nondescript hardware, and virtually all of it -- mostly streamers and speakers -- uses wireless technology. Much of it is affordable, simple to install, and can run on a home’s Wi-Fi network. Here are the most interesting products I spied while roaming the aisles of the SDCC with my Simplifi goggles on. All prices are in USD.

When I recently reviewed Yamaha’s R-N803 network stereo receiver ($749.95 USD), one highlight turned out to be the company’s Yamaha Parametric Acoustic Optimizer (YPAO) room-equalization software, which I found benefited the sound. YPAO has long been a feature of Yamaha’s A/V receivers, but the R-N803 marked its debut in a stereo receiver. Which led me to wonder: Why had it taken so long? It also got me wondering: Why there aren’t more stereo-only products with room-correction software?

Once a business with an all-you-can-eat model, media streaming has begun to carve out niches to serve more narrowly defined interests. Take Disney, which recently announced that it would pull its content from Netflix to create its own streaming platform aimed at parents of young children who eagerly consume Disney and Pixar movies. Then there’s FilmStruck, a service created by Turner Classic Movies and the Criterion Collection to stream their catalogs directly to equally eager cineastes.
