"When Harman, Datasat, BMW, Volvo, Pioneer, Arcam, Emotiva, Xiaomi, Oppo, and OnePlus want digital audio optimization solutions, they turn to Dirac," boasted a sign at the Dirac exhibit. But the demo was not of the Swedish company's world-beating room correction systems but of a newly developed system to enhance headphone listening for virtual reality and gaming.

THE VERDICT
Yamaha’s new flagship receiver packs nine amp channels into a well-built package.
Buying an A/V receiver has always been a challenge, even to the well informed. Incoming technologies add still more complexity. Sometimes, however, they also generate new priorities and narrow your choices. Sure, Dolby Atmos and DTS:X require you to add more speakers and make your system more elaborate. But if you want to run those formats in their most effectively enveloping configurations, your shopping expedition for a receiver has suddenly become a lot simpler.
Sony Pictures Home Entertainment has announced that it will support Auro-3D in some disc and “digital” titles. Auro-3D is an unusual method of immersive surround encoding that one-ups Dolby Atmos and DTS:X by offering not one, but two, height layers above the floor speakers in a 13.1- or 11.1-channel native mix. Until now it has been scantily supported in software, with just a few dozen Blu-ray releases, but this might be a game changer for the plucky little Belgian company. Auro-3D has also firmed up its hardware support with new (and more mainstream) receivers and pre/pros from Denon, Marantz, and Lyngdorf that support the necessary surround processing. (Note that the Denon and Marantz products require an optional $199 update.) Height-enhanced surround sound may be about to become a three-way horse race.

THE VERDICT
Speaker designer extraordinaire Andrew Jones continues his work for German manufacturer Elac with some of the best monitor-class speakers we’ve ever heard plus a provocative, app-driven sub.
There are a lot of ways to put together a home theater system. Small speakers—or, as I call them, monitors—are among the best foundations for a multipurpose room that isn’t cavernous in size. The audio industry used to pump out so many potentially interesting passive monitors (not to mention towers) that we could barely review a fraction of them. But with the increasing emphasis today on soundbars and powered lifestyle speakers at the lower end of the market, it’s becoming increasingly hard to put together small-speaker configurations for surround sound.
