When I walked into the Robyatt Audio room, I discovered that Robin Wyatt had come all the way from New York City to show people what a lovely, airy sound he could get from Jacintha’s “Here’s to Life” and other LP selections. “The man who recorded that LP used the same stereo Miyajima Kinsui cartridge that I’m using for playback,” he explained.

Jim Rush of PTE (Precision Transducer Engineering) of Orange, CA explained that he was using the system in his room, headlined by PTE’s The Phoenix self-powered, bi-amplified loudspeaker ($5700/pair), to conduct 10 different blind tests with five sequences. The results of his experiments, which he said demonstrated that most people couldn’t discern differences with a high degree of accuracy, are slated to be posted to PTE’s website.

One of many Colorado retailers that displayed at RMAF this year, Fort Collins Audio hosted the debut of the TSG planar ribbon tower line array loudspeaker ($29,000/pair). Unfortunately, the speaker sat unplayed in the corner of the room when I entered, replaced by the excellent Totem Earth ($8995/pair). Connected to a Hegel H20 amplifier ($5740), Hegel HD20 DAC ($1995), and Quicksilver Audio preamp ($3900) via Kimber Kable Bifocal XL speaker cable and Kimber Select 1126 interconnects, the system was producing fine, solid sound with nice color.

If there’s anything that will grab this whistler’s attention, it’s the sound of another whistler who knows what she or he is doing. Given that the first thing I heard when I set foot in the room from Pro Audio Ltd. of Tower Lakes, IL was the delightful sound of whistling on Livingston Taylor’s “Isn’t She Lovely,” I was primed for a good experience. And so it was, with the system’s genuinely lovely if somewhat light-bodied sound distinguished by a captivating sense of air that is the mark of good analog.

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, candor—and good music.

Near-holographic imaging—an 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 headshell—and the cartridge and stylus—maintain 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 there—and 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 mechanisms—from 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.
