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.

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.

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.

It was that rarest of rare occasions in audio-show reporting: I entered the demonstration room of a brand that was unfamiliar to me, and was impressed at once by a sort of musical rightness I seldom hear from modern playback gear. Sure, I was familiar with the company that made the CD player, preamp, and monoblock amps in use—Electrocompaniet, whose solid-state amps are among the few I consider worthy of comparison to the best tube designs—but the Austrian loudspeaker manufacturer Brodmann Acoustics was new to me. Their stand-mounted Festival S ($4500/pair), driven by a pair of Electrocompaniet AW180 monoblocks ($5425 each) allowed the solo violin in a Paganini work to have far greater than usual texture, tone, and presence. Based on my experience at RMAF, the pairing of these two brands is something you should go out of your way to hear.
