Open, detailed sound
Excellent dialogue intelligibility
Flex can be configured as wireless surround speaker

Some ergonomics issues
Inconsistent system stability

THE VERDICT
The B&W Formation system performs admirably in a number of respects. But unreliable stability, limited processing features, and no HDMI input make it a less-than-ideal option for 5.1 surround sound.

Blame it on Sonos. In the early 2000s, at what was then the Los Angeles headquarters of the Stereophile Guide to Home Theater, we were visited by a gentleman from that then largely unknown company who had a product he was eager to promote: a wireless speaker in a single, relatively compact box. I politely declined. It wasn't a good fit for our publication at the time, but I should have at least asked him about stock options!

THE VERDICT
Though it doesn’t come cheap, Naim’s newly revised Mu-so brings true audiophile sensibilities and surprising wallop to a well thought-out and full-featured wireless speaker.

The original Mu-so wireless music system released in 2014 was a first in the emerging "lifestyle audio" category—a truly high-end, wireless, multiroom speaker from one of the most respected brands on the planet. I auditioned the Mu-so back then, and what I remember most from the unboxing was its nearly 30-pound heft, and the manly, finned heatsink that ran the width of the back panel and threatened to cut any flesh that wandered too carelessly in its direction.

THE VERDICT
DALI’s Callisto 6 C towers provide a reliable option for high-performance wireless hi-fi, as well as high-res multiroom streaming when paired with the BluOS NPM-1 module.

Active speakers that deliver sound via wireless connections have become a hot category in the hi-fi world. Sound & Vision has reviewed a wide range of them—everything from cheap, compact cylinders that sit on your kitchen counter and respond to voice commands, to more advanced systems designed to deliver stereo or 5.1 sound in a living room or home theater environment. The new Callisto line from Denmark's DALI (Danish Audiophile Loudspeaker Industries) belongs to the latter category. You'll find no tiny drivers or molded plastic cabinets here, let alone a built-in intelligent assistant of the Google, Alexa, or Siri stripe. Instead, the Callistos merge the convenience of wireless audio with a traditional approach to high-end speaker design.

More optimized for TV sound than music

THE VERDICT
Sonos’ compact, Alexa-enabled soundbar offers impressive performance for the price. All in all, a smart value.

Without knowing history, you might dismiss the Sonos Beam as just another budget soundbar dropped into a largely undistinguished field. But as with most things Sonos, this attractive yet intentionally non-descript oval is significant both for the company and the audio business. Sonos execs have long seen the living room television as the most logical gateway for their wireless multiroom music system.

THE VERDICT
Sonos was slow to deliver a voice-controlled smart speaker, but with integrated Alexa (and Google Assistant arriving soon) in what amounts to a redesigned Play:1, they've created a nearly irresistible, low-cost intro to their wireless ecosystem.

The full impact of the home-based voice-actuated assistant, invented first by Amazon in the guise of Alexa, then followed by Google and now Apple with its Siri-driven HomePod, has yet to be felt. The category has loosely evolved into what we are now calling the "smart speaker," though it is not the speaker, but the microphone (or mic array) in conjunction with a network connection that imbues these devices with their extraordinary power. Sure, the speaker plays music, perhaps the simplest of its voice-controlled functions and (according to a recent study by NPR/Edison Research, the activity a smart speaker is still most frequently used for). But the opportunity presented by an artificially intelligent device that can respond to human language and trigger any number of events in our environment possesses extraordinary potential for transforming our lives. The fact that the most sophisticated of these voice interfaces to date, Amazon Alexa and Google Assistant, are offered in open, licensed platforms and being constantly advanced and promoted by two of the world's richest tech giants, suggests that we are on the verge of an explosion of innovation. The best is yet to come.

THE VERDICT
Riva Audio continues a tradition of excellent sound quality with the WAND series, the company’s first wireless multiroom speakers.

I first met Riva Audio founder Rikki Farr and chief engineer (now also president) Don North in the fall of 2014 when they marched into Sound & Vision’s New York City conference room to demo their first product, a Bluetooth speaker called the Turbo X. North was a youthful, glasses-wearing geek who had just enough of the right credentials and tech swagger to suggest he really knew what he was doing.

Voice-activated speakers are hitting the market hot and heavy with everyone vying to be the only system you’ll invest in. Amazon is hoping you’ll pick Alexa, and Cortana is hoping to get some traction in the market. Once you’re a Google family, odds are you’ll stay there. To that end, JBL just released a new line of Google Assistant voice-activated speakers, and the LINK 20 is the perfect balance of features, sound quality, and portability. Yup — that’s right — a voice-assistant that’s not only portable, it’s waterproof too so it can go anywhere.
