The German manufacturer ADAM Audio, whose high-frequency drive-unit technology is descended from that of Oskar Heil's Air-Motion Transformer, introduced their new Gamma loudspeaker ($22,000/pair), which is built around a 25mm-thick aluminum baffle: a departure from the honeycomb material used in elder ADAMs. Demonstrated with a pair of Cary SA 500.1 solid-state monoblocks ($4995 each), Cary SLP 05 preamp ($8495), and Cary CD 303T CD player ($6995), the Gammas were clear and distinctly articulate, with a pleasant balance overallalthough I wouldn't have wanted them to be an iota lighter.
I've heard TAD's high-tech CR1 loudspeakers ($42,000/pair) on other occasions, at other shows. But they've never sounded as good as they did at RMAF, where they were demonstrated with electronics from a new company called Zesto (a great, un-self-conscious name that sounds like an affiliate of Slusho, the imaginary Japanese soft-drink company created for the 2008 film Cloverfield). The source was a Merrill-Williams REAL 101 turntable ($7200) with Triplanar arm ($5800), Dynavector XX2 MkII cartridge ($1985), and Zesto Andros phono stage ($4300) and Leto preamp ($7500), plus GamuT D200 amp ($6000) and WyWires cabling which, like the Zesto gear, comes from Thousand Oaks, CA. On selections by Illinois Jacquet and others, this system sounded richly textured and very involving.
Thank goodness I wasn't shooting with film: It took several frames to get a decent photo of the Da Vinci DAC ($31,000) from the California company Light Harmonic. But I didn't mind spending all that time trying, as the music was superbly tactile and compellingthanks in no small part to amplification from KR Audio Electronics, represented at RMAF by the enduringly gracious Dr. Eunice Kron.

The three-way, 220 lb Avior loudspeaker from Rockport Technologies ($29,500/pair) uses the same beryllium tweeter as the company's $225,000 Arrakis, complemented with all-new midrange and bass drivers that are built around Rockport's proprietary carbon-fiber sandwich/composite cones. The Avior sounded truly impressive with a Playback Designs MPS-5 CD/SACD player/DAC ($17,000), Electrocompaniet EC4.8 preamplifier ($5129), BAT VK-655SE amplifier ($14,000), and cabling from Transparent Audio. A representative from the Omaha, Nebraska dealer The Sound Environment demonstrated the system with humor, charm, candorand good music.
Near-holographic imagingan audio ideal for some hobbyists!could be heard in the Nola suite, where the company's new KO loudspeaker ($9800/pair) was demonstrated with Audio Research amplification, Audio Research CD player, and Nordost cabling and Quantum QX4 EMF-control devices. The 3.5-way KO uses aluminum-cone woofers and is described by designer Carl Marchisotto as offering 90dB sensitivity and a nominal 8-ohm load.
North American distributors Rutherford Audio were on hand with the latest full-range loudspeaker from the German company ELAC, with celebrates its 86th anniversary this year. (Brit-fi fans such as myself will remember ELAC as the manufacturer of the silky-smooth aluminum-dome tweeter from the first and best version of the Acoustic Energy AE-1.) Their new 249 BE loudspeaker ($8000/pair), the woofer cones of which are faceted for rigidity, sounded fine with Burmester electronics. Bruno de Lorimier of Rutherford Audio invited us to guess if the singers on one recording in particular were wearing boxers or briefs; the answer, of course, was "yes."
A pivoted straight-line-tracking tonearm? The description is far less oxymoronic than it seems, given the arrival of the Schröder LT tonearm ($8900). This fascinating and apparently very well-executed design works by augmenting the main arm pivot with an extra pivot at the base, the latter said to offer exceptionally low resistance to the arm and cartridge as they follow the inward spiral of the groove. The geometric relationship between the two pivots is such that the headshelland the cartridge and stylusmaintain perfect tangency to the groove from beginning to end. Thus the headshell requires no offset angle, which also means that no anti-skating force is required. Very cool.
Among the many delights in the Audio Feast room: a prototype of an autoformer-based volume control called the Finemet TVC (price TBD). The real attraction, of course, was the fact that Audio Feast played real music in their room. (They were playing a Miles Davis disc when I was thereand I don't mean one of the umpteen audiophile reissues of Kind of Blue.) I look forward to getting to know Audio Feast in the months ahead.
I finally got to meet one of my audio heroes, John Tucker: founder of Exemplar Audio and co-designer of the legendary Exemplar Horn loudspeaker system. Tucker, who spent the early part of his career working for NASA at the Johnson Space Center, is an engineer and software designer who keeps a distinctly open mind when it comes to the audible effects of seemingly anomalous mechanismsfrom acoustic resonators to powered cables. (John is also featured in an article of mine that will appear in the Autumn, 2012 issue of The Fretboard Journal.) These days, Exemplar's products include a heavily modified version of the Oppo 95 disc player ($3500, including base Oppo unit) and a line of active interconnect and speaker cables called Portals.
