CES 2015

There's been some back and forth on AudioStream.com and other forums about how to best play back DSD and PCM, with some finding that having a single digital section converting both formats is less than optimal.

T+A decided that in order to do both formats justice in a single product, they would have to create completely independent decoding and analog output sections (including two sets of analog output jacks on the back!). The result is a design that the company believes is a unique and "fully optimized approach to the decoding of both PCM and DSD."

Wharfedale—which now bills itself "Britain's Most Famous Loudspeaker. . .Since 1932"—introduced the Diamond 200 series at CES 2015. The series includes the model 210 and 220 bookshelf monitors, model 230, 240 and 250 floorstanders, model 220C center-channel speaker, and model WH-D8 and WH-D10 subwoofer.

As I was leaving the Venetian after closing up the Stereophile room on the last day of CES, I bumped into AudioQuest's Steve Silberman in the elevator. "I've got one left, take it," he said and handed me the little USB thingie in my photograph. "It's going to cost $49 and will be available in the spring."

Working like a stereopticon, Edgar Choueiri's Bacch-SP provides up to a 32dB reduction of interaural crosstalk, not with headphones, but with everyday stereo loudspeakers. And without the coloration that previous solutions, like a physical barrier between the ears, are plagued by.

Gilad Tiefenbrun, Managing Director of Linn Products (above), along with the Scottish company's Technical Director Keith Robertson, gave me a convincing demonstration of Linn's Exakt system. According to Linn, "Exakt pushes the lossless digital signal path all the way to the speaker," turning the loudspeaker into "an intelligent, connected, software-upgradeable product. This enables a wide range of performance- and personalisation-enhancing capabilities in design, in manufacture and in your home."

Closing three days of Hi-Res presentations at CES 2015 were (from left–right) Maureen Droney, Senior Executive Director of The Recording Academy's Producers and Engineers Wing and a recording engineer who has worked with Santana and John Hiatt; Marc Finer, whose Digital Entertainment Group (DEG) consults with Sony and other entities as he attempts to align messaging on the hi-res front; and Robert Heiblim, Vice Chair of the Consumer Electronics Association's (CEA) Audio Division.
