According to Amazon, the e-commerce site’s hottest product category during the 2017 holiday season was audio. This is not to say that most Amazon shoppers were spending money on amplifiers, bookshelf speakers, or even headphones. The audio product that everyone wanted to find under their tree was the Echo Dot, a voice-activated Wi-Fi speaker that sells for $50 USD.

In an editorial posted late last year, I surveyed the limited field of hi-fi components that include room-correction processing. One product I mentioned was Trinnov Audio’s Amethyst ($10,000 USD), a stereo DAC-preamplifier featuring Trinnov’s proprietary Optimizer. Interviewing a Trinnov rep about the company’s innovative approach to dealing with the interactions of loudspeakers with domestic rooms, recording studios, and movie theaters made it clear that the Amethyst was something I wanted to check out in my own system.

Reviewers' ChoiceWi-Fi speakers are an easy option to recommend. You might be a millennial looking to upgrade from a Bluetooth speaker, or an audiophile seeking to downscale from a component-based system -- either way, a Wi-Fi speaker could very well be the ticket. But most Wi-Fi speakers aren’t much to look at: Sonos made the mold with its own nondescript designs, and most companies since have used Sonos as a template.

Control4, a company well established in home automation, makes virtually everything required to run a Smart home, from the controllers that act as a system’s brain to the touchscreens and keypads that provide user interface with such a system. In 2017, Control4 acquired the loudspeaker and audio electronics manufacturer Triad, and since then has ramped up the audio aspect of its product offerings by adding multiroom amplifiers, speakers, and subwoofers. Another recent addition has been its EA series of controllers, a line that supports the streaming of high-resolution audio files.

The PW 300, the latest addition to Paradigm’s family of wireless speakers, joins the PW Soundbar and the PW 800 and PW 600 all-in-one speakers. Vince Hanada recently reviewed the PW 600, in a system that included the PW Soundbar, for SoundStage! Xperience. “Configured as a stereo pair,” he wrote, “the PW 600s sounded outstanding, easily rivaling separate speakers and electronics costing many times their $1198/pair price.” That’s seriously high praise for a Wi-Fi speaker -- high enough to make me wonder if the PW 300 ($329 each) would be equally impressive.

Reviewers' ChoiceGerman audio manufacturer Elac has attracted plenty of attention in the last few years, much of it due to new speaker lines designed by Andrew Jones, an audio engineer who’s developed models for companies ranging from KEF to Pioneer. But making speakers isn’t all that Elac is up to. The company recently introduced a range of electronics, including an integrated amplifier and a music server, and has even rolled out a high-end turntable. Now, with the Discovery Z3, Elac turns its attention to Wi-Fi speakers.

What’s in a name? For old-school audiophiles, the name Thiel conjures up images of stately speakers in sumptuously finished cabinets of natural wood, of company founder Jim Thiel’s emphasis on the principles of time and phase coherence, and his use of coaxial drivers and first-order crossovers in his designs to achieve those ends.
