CES 2011

They include the T 787 ($3499) and T 757 ($1499) a/v receivers, with seven times 120 and 60 watts respectively, both fully up to date with HDMI 1.a for 3D compatibility. Also shown was the T 187 pre-pro ($2499). The pricier receiver and pre-pro can be outfitted with an optional Control4 module.

As you'd expect, I'll start with a cheap joke: Each of these Silbatone Acoustics SGW-24 speakers can double as a studio apartment. Even if you have a roommate. But believe it or not, this massive horned loudspeaker has a plausible reason to exist in the home theater realm: It's an attempt to recreate Western Electric theater speakers from the early days of the talkies. Western Electric, in case you didn't know, was the manufacturing arm of the Bell System (later AT&T) for more than a century. Oh, and it was my father's employer for several decades, though he worked on the phone side of the business, not the cinema side. More on the SGW-24 here. Believe it or not, it had dynamic power, the focus associated with horns, and even a certain delicacy. But I would say that, being a Bell Baby.

Running wires to the rear speakers of a 5.1 or 7.1 system is always problematic. Several companies demonstrated wireless add-on devices, but the Link-Mount is the most unusual and clever solution I’ve seen so far. The wireless receiver/amp is built into a universal speaker wall bracket. A DC power cord is then run through the wall to a termination plate where you connect the wire to a transformer plugged into an electrical outlet. Since it’s DC running through the wall, no electrician is necessary. Pricing is in the $400 range for a pair of brackets and a transmitter.

Dolby Home Theater v4 is, as the name suggests, the fourth-gen implementation of sound enhancement for PCs from Dolby Labs. It incorporates trickle-down technology from Dolby Volume (best known for its use in surround receivers) including volume leveling, dynamic enhancer, and spatial virtualizer. First of two demos at the Central Hall sanctum involved a laptop with and without DHTv4. It was a huge difference: muffled sound versus rather bright sound. In the second demo, another laptop bitstreamed into an Onkyo receiver with Focal sat/sub speakers. This time the benefits were more subtle, though still discernible: a larger soundstage and more solid imaging. The technology will be shipped with laptops including Acer, Lenovo ThinkPads, and more to be announced. In another corner of the Dolby booth a Nokia N8 smartphone with built-in Dolby Digital Plus (a high-quality lossy surround codec) mustered pretty good surround via Harman Kardon receiver and Focal floorstanding speakers.

You'll probably read some blogs from our two-channel colleagues about The Sonus Faber, a fridge-size floorstander selling for $200,000/pair in a limited production run of 30 pieces. Playing a solo cello recording, TSF mustered some of the best sound at the show. But there were also brand new home theater worthy models at Sonus Faber's suite in the Venetian, namely the Toy Monitor Grand (center) and Toy Wall (upper righthand corner). They're sold in pairs, for $2,000 in both cases, but you can add the Toy Center for $995/each.

This isn't even the main show floor. It's just the midday activity in the Las Vegas Convention Center's grand entryway.

Here's a way to encourage your kids to write on the wall—that is if the wall is an LG Touch TV which functions like a huge, modern-day, multi-colored Etch-A-Sketch. It's also a 2D plasma HDTV. But it's clear that not all of us are Rembrandt.
