As I write this, we’re fresh back from our annual pilgrimage to Las Vegas for CES. For me, the most exciting news for home theater buffs swirled around Ultra HD, both the launch of the first HDR (high dynamic range) UHD televisions and the announcement of details on forthcoming UHD Blu-ray Discs. We explained HDR in a feature in our January issue, but when that went to the printer we assumed Dolby Vision would be the widely adopted solution for bringing HDR’s uber-highlights to sets and that it would take a while before we saw affordable TVs that could achieve HDR-like peak brightness. Nor did we expect to see the required HDRencoded content to be coming anytime soon. But nearly all the TV makers showed prototypes or introduced models with HDR technologies.…

Jacked Up…Again Responding to Mark Fleischmann’s response to “All Jacked Up” (Letters, December), I either did not clearly make my point, or he missed it completely. Yes, I agree that surround sound processing is best handled in the receiver or…

Meridian MQA Lossless Processing NEW GEAR, TOP NEWS, HOW TO, AND MORE... A genius never stands still. Bob Stuart, digital audio pioneer and inventor of the Meridian Lossless Packing format that forms the basis of Dolby TrueHD, recently launched MQA (Master Quality Authenticated), which he modestly calls a “revolutionary British technology” that will change the way we hear music. Truth is, given Stuart’s track record, you have to take his proclamation seriously. Early listening sessions suggest that he may be onto something. Something big. MQA is a proprietary digital encoding system used during recording or mastering that captures “extremely high-frequency timing and detail in an audio signal” and encapsulates it in a form that can be streamed or downloaded via FLAC or any other lossless file format. The thechnology uses an advanced sampling…

Vizio Sponsored the AFI Fest for the American Film Institute in Hollywood. Among many other niceties, attendees got to charge their phones and enjoy a drink while watching P-Series TVs showing Ultra HD content... Pioneer and Onkyo moved ahead with a merger that has Pioneer buying a 14.95 percent stake in Onkyo, making it Onkyo’s third biggest shareholder after Otsuki Strategic Holdings and Gibson, the guitar manufacturer. What will happen to Pioneer’s world-class AVRs and other audio products was unknown at press time... The Urban Movie Channel launched from the folks at BET. It includes documentaries, comedies, horror films, and stage plays. A free trial through February 4 gave way to a $2.99/month charge... TV-Everywhere Viewers will quadruple from 5.6 billion in 2010 to 11.32 billion worldwide by 2020, predicts Digital TV Research.…

Get Into the Groove PRICE $99; TWO FOR $179 CAN A SMALL DEVICE THAT CLIPS to your belt produce the visceral sensation of a live musical performance or the deep, pulsating bass felt in a dance club? Can it wow mobile gamers with spinetingling bass? Kickstarter-funded Woojer (“See Me, Feel Me,” April 2014) aims to do just that with a “wearable subwoofer” that connects between your music player (or any audio source) and headphones. Technically speaking, Woojer is a polyphonic tactile transducer that converts audio frequencies below 500 hertz into low-frequency vibrations to “make your body feel like it is exposed to high acoustic energy.” I was intrigued by the premise (and somewhat skeptical), so I got my hands on a Woojer and tried it out with JBL Synchros E40BT headphones and a handful…

PERFECT FOCUS JOHN SCIACCA Gone in Sixty Seconds A few years ago, I attended a product demonstration at CES by a company famous for touting how durable its hard drives were. In fact, the company—ioSafe—calls its products “disaster proof hardware” and used CES to deliver extreme, over-the-top demonstrations to prove just what kind of damage their drives could withstand and still protect all of the data stored within. One year, ioSafe set one of its drives on fire, sprayed it down with a fire hose, dropped it onto concrete from 20 feet up, and then drove over it with a backhoe. Another year, they let members of the press blast a drive with a 12-gauge shotgun. At the demonstration I attended, they put a drive in a “Cage of Death” and repeatedly zapped it…
