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.
Danny Richie of GR Research, which supplies drive-units and other components to the DIY community, designed and assembled these panel loudspeakers using push-pull planar-magnetic drivers from BG Corporation. The loudspeaker, which hands over to a servo woofer at 200Hz, sounded open and detailed with all-battery-powered tube electronics from Dodd Audio. (There was also, on static display, a gorgeous one-off Dodd preamp using 6C33C tubes for voltage gain!)
There's pretty much only one way to hear Rammstein at a hi-fi show: Visit the demonstration room of Swedish-based, American-built Sjöfn HiFi. (As close as I can tell, the name is pronounced hoofin, although you have to do something funny to the H.) Sjöfn 's Managing Director, Lars Erickson, approaches the selection of demo music with a adventurousness and whimsythis is the man who turned me onto the great Israeli trance duo, Infected Mushroomand the sound of his new two-way loudspeaker, The Clue ($999/pair, direct, including shipping) was up to the task. As with earlier Sjöfn designs, I have no idea whatsoever how he manages to wring such enormous scale, clarity, and impact out of such a tiny box. But he does.
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.
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.
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 useElectrocompaniet, whose solid-state amps are among the few I consider worthy of comparison to the best tube designsbut 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.
Strange that I should travel 1800 miles to hear products that are designed and manufactured less than two hours from my home. Happily, the McIntosh experience at RMAF was worth the effort, especially inasmuch as the hallowed brand distinguished itself by playing real music as opposed to audiophile chestnuts. (Think of it!) I especially enjoyed some selections from the Beatles' Anthology 3 collection, played via JRiver software on an HP laptop, through a McIntosh C50 preamp ($6500) and MC452 amp ($7500), along with the McIntosh MEN220 room-correction system ($4500, which includes the microphonebut not the standseen in this photo). Rounding out the system were the company's recent XR100 speakers ($10,000/pair): certainly the best McIntosh loudspeakers I have yet to hear.
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.
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.
Cardas Clear Skythe sample to which VP of Sales and Marketing Andy Regan is pointing in this photois the latest and most affordable of the company's "Matched Propagation" speaker cables, and is said to be ideal for owners of high-efficiency loudspeakers. The retail price is $775 for an 8' pair, terminated with Cardas spade connectors. (I have requested a review sample, and hope to report on the Clear Sky cables within the next couple of months.)
