CES 2012

A look inside the PrimaLuna DiaLogue Premium integrated amplifier ($3199) reveals neat point-to-point wiring and high-quality parts, like Takman resistors and SRC tinfoil capacitors&#151stuff that an amp-lover like Art Dudley might appreciate.

Ypsilon's Demetrius Baklavas (right in photo) and Ypsilon's US distributor, Brian Ackerman of AAImports, demonstrated the Aelius amplifier to John Atkinson (left) and myself—the amplifiers were doing a fine job of producing dynamics and superb open highs from the plasma tweeters of the new, floorstanding Lansche 7 loudspeakers.

Joseph Audio's Jeff Joseph is always a smiling, positive presence at CES and other shows, and always seems to have something new in his speaker line, even if "new" is defined as "finally in production." This describes the Perspective ($11,800/pair), making good sounds with relatively affordable Bel Canto equipment ($2995 digital receiver and CD3 transport). The tie Jeff is wearing has cartoon figures designed by Joshua Joseph, Jeff's 11-year-old son.

JL Audio's home high-end audio subwoofer engineer, Brett Hanes, proudly shows off the company's new $1700 ES-112 subwoofer (wood finish) that uses clever engineering principles to coax better performance and value from a less-expensive product. The ES-112's woofer features the company's only dual-spider driver construction, a smaller voice-coil, though the cone is designed for the same 3" peak–peak excursions found in the company's flagship f212 and Gotham models. Other construction simplifications—you change line input voltage by changing fuses in external fuse holder—make the product more adaptable for international sales. It also has a high-pass output with variable frequency crossover, which will be appreciated by those of us using subwoofers in a two-channel home audio system.

The great thing about audio shows is whom you bump into in the corridors. Here is legendary engineer John Curl, who has been designing the superb-sounding Halo series of amplification components for Parasound—dig the name badge which, instead of the usual "Exhibitor," "Press," "Sales Representative," or "Consultant," simply and very appropriately says "Engineer."

I had planned to attend the press conferences by Panasonic, Samsung, and Sharp, all scheduled for Press Day, but it seems that every single person with a Press badge had exactly the same idea, and the resulting crowds were at least as big as at the CES Unveiled event. In fact, about an hour before the scheduled Samsung press conference, CES staff announced that the number of people in the line-up exceeded the capacity of the hall, and not everyone could be admitted. I gave up on both Samsung and Panasonic, but was Sharp was different. They had sent emails to a selected group of journalists, including yours truly, designating them as VIPs, and special tickets to be printed out, which would allow these individuals entry to the press conference before everyone else. Even if I had not been all that interested in whatever Sharp was going to announce, being called a VIP meant that I just had to attend. And, as I walked in, who do I see but my colleagues, Kal Rubinson (left) and Tom Norton (right)? We had our choice of seats, up front. It's good to be a VIP!

Harman Specialty Audio's Kevin Voecks demonstrated his latest portable room-response testing system, an iPad 2 running Studio Six Digital's "Audio Tools" iTunes app. (A favorite of JA’s.) The iPad 2 plus a $50 external mike and an accessory box from Studio Six becomes a portable audio test system with up to 1/48-octave resolution. Kevin used this tool to set up Revel's new M106 and F208 loudspeakers on the 35th Floor of the Venetian Hotel. He demonstrated frequency response graphs and a virtual SPL meter—seen in detail as a graphic representation of a huge analog SPL meter on the iPad screen.
