Checking out the Reference 3A speakers (Grand Veena, MM de Capo i, etc.) in Divergent Technologies' room at T.H.E. Show, I noticed that the center of the midrange and mid-bass drivers looked different. Divergent's Tash Goka was not in the room, but the person who was there introduced himself as the one responsible for the modification of these drivers. He's Ricky Schultz, inventor of the Surreal Acoustic Driver Lens, a small plastic device that is glued to the drive's dustcap, and has the effect of broadening the dispersion. The Surreal Acoustic Driver Lens is being incorporated into the production of all Reference 3A speakers. It's an OEM product, not available to consumers, and, according to Schultz, it has the potential to improve the performance of many loudspeaker drivers. He proceeded to provide me with the explanation of how the device works, but it quickly went over my head.

The business card of Dali's Kim Kristiansen states his position as "Director, Innovation." And, to judge by the illustrated talk he gave, Kristiansen and his associates at Dali have been working hard at producing innovations. The drivers for their latest speakers have a new linear drive magnetic system that uses a soft magnetic compound (SMC), which radically reduces distortion. Listening to the well-known recording of Misa Criolla on the demo system with the Epicon 6s (Primare CD player and electronics), which incorporates all the latest advances, I was impressed by the clarity and precise focus on the voice of José Carreras.

This Kim Kristiansen slide illustrates the effectiveness of Dali's SMC/linear drive magnetic system in reducing distortion. I believe the lowest curve shows the distortion levels of this the woofer—built completely in-house—that uses the linear drive magnetic system with SMC.

Although I don't consider myself an expert on headphones by any means, I know that they fall into three basic categories: (1) circumaural (pad around the ear, the back closed or open) (2) supra-aural (pad on the ear), (3) in-the-ear (tightly or loosely fitting). (There were also the Jecklin Float headphones, which involved a pad on top of your head, with the transducers being positioned some distance from the ears. These have never enjoyed widespread success, and I don't think they're being made any more.) However, I was intrigued by one of the pre-CES emails, announcing "ear-free" headphones.

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.

I know of speakers where, depending on the crossover, the same 5" or 6" driver is used as midrange or as woofer, but I've never encountered a speaker where a driver normally designated as a tweeter also functions as a midrange. This is the unusual design approach taken by McIntosh in some new speaker models, including the $10,000/pair XR100, and, judging by the sound, it certainly works for them. The driver is a 2" metal dome: eight of these are combined to serve as midrange, with two more as the tweeter flanking a supertweeter.

Atlantic Technology's AT-1, which uses their patented H-PAS venting technology, was one of the hits of last year's CES, and the positive impression was confirmed in Erick Lichte's review (September 2011). The H-PAS approach has now been applied to the new AT-2 ($1800/pair). The –3dB point is specified as 41Hz, which I'm told is an anechoic figure. This normally translates to in-room response to the low 30s, and the sound of the AT-2 in the Venetian's less-than-ideal space seemed to confirm this.

The business card of Eventus Audio's designer, Domenico Fiorentino, says "Fine Italian Products." But even if it didn't say that, even a casual look at the curved lines and impeccable finish of the Eventus speakers will immediately make you think that the speakers must be made in Italy. Their latest iO line is designed to bring the quality of their cost-no-object offerings to a more affordable level. North American prices are yet to be determined, but the stand-mounted two-way iO is 2500Euros/pair and the iO.f three-way floorstander is 5500Euros/pair. Fiorentino is pictured here with Angie Lisi of Audio Pathways, the North American distributor of Eventus.

The GoldenEar Triton Two, which I reviewed in the February 2012, issue, is my favorite speaker at anywhere near its price ($2499/pair until February 1, when it goes up to a still-very-reasonable $2999/pair). The Triton Two now has a "little brother": the Triton Three ($1999/pair), is a smaller version of the Triton Two. The resemblance goes beyond the physical; listening to a pair of Triton Threes, I was very much reminded of the Twos: the same sort of expansive soundstage and bass that was very nearly as impressive as I'm familiar with from the Twos.
