"The technology to create a full, wireless, 5.1 channel audio system simply wasn't available before, "said Mike Gough, B&W's Senior Project Manager on the Liberty System, "so we waited until it was possible to do it right." The Liberty employs a proprietary, robust wireless protocol with channel switching capabilities—called dynamic channel selection—to avoid interference from existing WiFi networks. Its wireless transmitter broadcasts 8 separate channels, allowing for full 5.1 in one room, and a stereo setup in a second room. Alternatively, the Liberty can support 4 separate stereo zones throughout the house.

Paul Barton, founder and chief designer of PSB Speakers International, plans to manufacture a new series of loudspeakers he is calling "Imagine." This line will feature new finishes and styling. The enclosures will be curved, both front to back and top to bottom. To create this shape, PSB is laminating multiple layers of MDF, w2hich is then braced to a mold. Radio frequency waves are directed at the enclosure shell for 15 seconds that quickly sets the glue. Once the enclosure is stable, holes are machined as the exact places required, which eliminates the tedious job of making ultra-precise adjustments when an enclosure is built around the drivers. PSB also uses a method of adding color after the first coat of clear sealant is applied to the veneer, so the resulting finish shows the wood grain but also has a rich, red color.

The Sumiko suite at CES provided a huge listening space to introduce the new Vienna Acoustics' full-range, four-way Die Musik loudspeaker ($25,000/pair). Designed by Peter Gansterer (see photo), a pair of Die Musiks produced some of the best sound I heard at the show. The speakers were positioned quite far apart against a side wall, and the listener sat on a couch closer to the plane between the speakers than the distance between the speakers. This created a very wide, coherent soundstage quite unlike any other than I heard at the show. Bass response, which was superb, actually could be credited, in part, to a huge REL Studio 3 subwoofer, which was parked and running in the nearest room corner.

Escalante Design's CEO and Founder, Matthew Waldron, and the company's design engineer, Tierry Budge, were on hand to introduce the $11,000/pair Pinyon, a lighter and less expensive version of their Fremont loudspeaker, which I review in the Febraury issue of Stereophile. Weighing 35 lbs each, the Pinyon includes two direct-coupled 6.5" woofers, and the same 1" ScanSpeak ring-radiator tweeter found in the Fremont. It comes with the Hoodooh Monitor stands that have a brushed aluminum inlay. Waldron had it playing with the 210 lb, 12", powered (500W), UINTA subwoofer, which is rated from 16–100Hz.
