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 CES 2017 demo of the TAD Micro Evolution One ($12,495/pair)—shown here with Jonathan Derda of MoFi Distribution, the importer—provided convincing proof of the engineering skill of TAD's current Japanese designers. The sound (with all TAD electronics) was simply superb…

There were lots of turntables at the show, but the one that intrigued me the most was the Calibre Mk.101, from Audio Excellence, the Toronto-area dealer, which is making its first foray into the turntable business. The Calibre Mk.101 has a with a marble plinth, 1.5" thick acrylic platter, AC motor with speed regulation, high-quality polished bearing, and looks elegant without being ostentatious. The price of $1999 includes a good-quality arm, with further arm upgrades available. Audio Excellences stated aim in introducing the Calibre Mk.101 is "the best reproduction of records at the lowest price possible—making turntables we would own."

Would you like to take "your high-end system to a whole new level of accuracy, from high-fidelity to acoustic fidelity?" That's what the Trinnov ST2-HiFi loudspeaker/room optimizer ($6200) promises. And it looks like a pretty sophisticated device, measuring the impulse response of the loudspeaker in the room, analyzing the room modes, and automatically computing FIR and IIR filters to improve the dominance of direct sound over late reverberation, equalizing the response in both frequency and time domains. The ST-2-HiFi is supplied with a calibrated microphone array; once that's placed in the listening area, all you have to do is press a button and the ST-2-HiFi does the rest. Comparing the sound of a pair of Sonodyne amplified speakers before/after Trinnov ST-2-Hi-Fi correction, I noticed that the imaging became considerable more precise after the ST-2-Hi-Fi processing, and the bass seemed tighter.

I ran across the poster above in Canada HiFi magazine: an announcement of the launch of a new audio store with an evening of vinyl playback. Located in the town of Orangeville, Ontario (population 30,000, about an hour's drive from Toronto), the store, with the intriguing name of Aardvark Boutique Audio, hadn't opened yet, but the event, taking place in the Orangeville Opera House, promised "Canadian Musicians On Vinyl—In Amazing Hi Fi Sound." I had to go and check it out.

My first encounter with the Acarian Alón IV was at the 1992 Las Vegas WCES. I was doing the show report dealing with speakers, and there was already enough advance buzz about the Alón IV that I put it on my "Speakers I Must Listen To" list. And listen I did, at some length, and came away impressed with their open quality and well-defined soundstage. In discussing reviewing assignments with John Atkinson, I told him that the Alón IV was one of the speakers I wouldn't mind spending some time with. (The list also includes the WAMM, the MartinLogan Statement, and the Apogee Grand, but I'm not holding my breath.)

Coming from the pro market, where active loudspeakers have been the norm, ATC is a major advocate of the active approach. According to ATC, the advantages include more accurate crossovers, lower intermodulation distortion, improved frequency response and stereo matching, and better low-frequency control. The active speaker from ATC being demoed at CES was the SCM40A, ($12,999/pair; $6999/pair in the passive version).

Adam Professional Audio is a German company that makes loudspeakers aimed at, as the name suggests, the professional market; their list of users include Abbey Road Studios and Lincoln Center. They're now poised to enter home audio. They had several of their speakers on display, but the only ones actually playing were in a large home theater demo room. The demonstration piece was the "chase" scene from the latest James Bond movie, Casino Royale, and all I can say about the sound was that it was loud. (Putting on my hat, I can also say that the projector's color saturation was set too high.) However, reading the product literature, it's clear that the speakers represent a formidable amount of technology. The tweeter and midrange driver are based on the Air Motion Transformer principle developed by the late Oskar Heil, called Accelerated Ribbon Technology (A.R.T.) in Adam's implementation. (Klaus Heinz, Adam's chief engineer, worked with Heil.) The woofers have a honeycomb-structure diaphragm. The Adam Tensor Betas that served as the front L and R speakers use two 11" woofers and a 7" one, plus two midrange units and a tweeter. Powered with B&O ICE module. class-D amplifiers, a pair of Beta Tensors cost $60,000. There are two other speakers in the Tensor series, all semi- or fully active, the prices varying from $30k to $80k.

The Adam is yet another loudspeaker manufacturer that uses drivers that are descendants of the Heil AMT tweeter. Adam's Classic Mk.3 uses what they call Accelerated Ribbon Technology (X-ART) for the midrange as well as the tweeter, and 2x7.5" HexaCone midwoofers. The Classic Mk.3 is available in passive ($7000)/pair or active ($10,000/pair) form, the latter for the studio professional market. A brief demo—with Cary Audio electronics—sounded convincingly full-range and dynamic. I understand that Kal Rubinson is getting a pair of these for review in Stereophile.
