Readers with really long memories may recall the ESS Heil speakers, which had a tweeter whose working principle was described in ads as being like squeezing a cherry pit. Oskar Heil was undoubtedly a gifted inventor, and the Heil "Air Motion Transformer" principle is gathering new adherents. Elsewhere in this show report blog, I discuss the products from Adam Professional Audio, whose Accelerated Ribbon Technology is a variant of the Air Motion Transformer principle. Speakers from the Chinese company, Mark & Daniel, fall in the same category. They call their drivers "Directly Responding Emitter by Air Motion Structure" (DREAMS). The pair of Mark & Daniel Aragon Monitors (CN$5500), mounted on Aragon stands ($1900), which act as bass extenders. They sounded quite good, driven by the new Audio Oasis AMP-D1 amplifier (100Wpc, class-D, Made in Canada, CN$1495).

The Parrot AR.Drone 2.0 has nothing to do with audio, high-performance or otherwise, so it arguably doesn't belong in a Stereophile show report, but I'm assuming that some readers are gadget-philes as well as audiophiles. The AR.Drone 2.0 is a toy, but not "just" a toy: it has two cameras, so you can shoot aerial helicopter-type shots and view them live on your iPad. Wouldn't you have wanted one of these when you were a kid?

The advent of digital cameras has re-kindled my interest in photography, and I enjoy discuss photography in person and on some Internet forums. Doug Schneider of (left) is another "photo guy," and one I know likes to use flash in his photography. I avoid using flash whenever I can, but I do use it sometimes; lately, I've been having more success with flash using the Gary Fong Lightsphere II, a light diffuser that bears a resemblance to something made by Tupperware. I had the Lightsphere II with me at the Show, so when I ran into Doug at FSI, I was excited about showing him this useful if strange-looking gizmo. He then took out his Lightsphere II from his camera bag, and we were ready for a "duelling Lightspheres" photo opportunity.

"DAL firmly believes that a full set of credible measurements, made by qualified engineering staff using state-of-the-art equipment and facilities, can reliably predict the potential of a loudspeaker to accurately reproduce the complex sounds of music."—Dunlavy Audio Labs

The first time I encountered Dunlavy's Signature Collection loudspeakers was at the 1993 Chicago Summer CES. I was familiar with, and had a lot of respect for, the speakers John Dunlavy had designed for the Australian Duntech brand, but I thought this new line clearly transcended his previous efforts—and at significantly lower prices. The model that I ended up reviewing—and, after the review (Vol.17 No.4), buying—was the SC-IV, subsequently honored as Stereophile's 1994 Loudspeaker of the Year and Product of the Year. In 1995, the SC-IV underwent changes, including a new woofer and a modified tweeter, resulting in some sonic improvements (see my Follow-Up review in Vol.18 No.3).

Dynaudio took a decidedly computer-oriented approach to providing a system for under $5000, with a choice between two powered wireless speakers: the Xeo 3 ($2300/pair) and the Xeo 5 (at $4500/pair, just under the $5000 limit). And these speakers are serious high-end products, not built-to-a-price budget offerings. You save on not having to buy an amplifier or cables (not always a trivial amount). The only catch is that there is no source component included; it's assumed that the consumer already has a suitable computer and/or iPod, iPad, or similar device.

I have a lot of respect for Dynaudio speakers, and have enjoyed listening to them at various shows, but I've never been as taken with one of their speakers as I was with the new Confidence C1 Mk.II ($8200/pair). With Naim amplification and digital source (including a Squeezebox Touch), the sound was simply exquisite, with highs that were revealing and yet not clinical. The legendary Esotar2 tweeter (shown in the photo) has apparently undergone some evolutionary development, and continues to maintain its status as the best dome tweeter in the world.

I think after every audio show I've attended there was some product that I realized too late I should have checked out—typically, when somebody later said to me "Did you hear the XXXX speakers? I thought they were great!"

After CES 2012, there was one product—actually, a line of products—that I had fully intended to seek out, but somehow this intention did not translate into action. It was on the plane returning home that I realized that I missed seeing the new wireless speakers from Dynaudio. I made a note to myself to make sure that one of the first rooms I'll visit at SSI 2012 would be Dynaudio's.

I've always thought of Fujitsu-Ten as a company that manufactures car stereos. However, it turns out that they have a special division producing a line of home-audio speakers using single drivers of their own design. That's right: no woofer, no tweeter, no coaxially mounted woofer and tweeter—just a single cone driver, claimed to cover the range from 40Hz to 20kHz. In the top model, the TD712z ($7000/pair), this drive-unit is mounted in a rigid, egg-shaped enclosure. The sound of these speakers, driven by an Audion Sterling Plus Mk.II tube integrated amplifier ($2950), was simply stunning in its clarity and focus.

SSI had a display of vintage gramophones and radios, courtesy of Montreal's Emile Berliner Museum. They've had this for several shows now, and it's always wonderful to see these artifacts that tell the history of our hobby. The Museum is member-supported, and publishes a pamphlet, His Master's Voice, four times a year, in English and French.
