While being PC is always a bone of contention in the audiophile community, sonic correctness goes without question. In a nice-sized room in the Marriott Tower, Lyngdorf’s Steve Colburn held a series of extremely convincing demonstrations of the complete Lyngdorf room perfect correction system. Using Triad speakers, Colburn’s before and after treatment samples of a percussion CD with lots of low bass were eye-opening. Quelle difference! If only Steve could have corrected for the people in the far corner who insisted on blabbing through the entire demo as if no one else mattered.
I've always wanted to hear Harbeth loudspeakers, but never before had the opportunity. All I knew about them was that they were quintessentially English, whatever that was supposed to mean.
I've always wanted to win the lottery so I could buy a pair of Jed Barber's much-coveted Joule Electra tube amps. I've spent hours in the Joule-Elrod room at several CESes, always entranced by the sound, but have never before heard the Joule LA150 Mk.2 preamp ($7000) and VZN 100 OTL monoblocks ($19,000/pair) paired with Merlin VSM MXE loudspeakers ($10,500.pair) and the Audio Aero Prestige CD player ($14,000). Wired with Cardas Golden Reference, this system did a superb job of bringing out the lovely, warm, full-range sound and delicious richness of Gary Karr's double bass on his Cisco Systems Adagio d’Albinoni CD.
The fourth annual Rocky Mountain Audio Fest is taking place this weekend at the Denver Tech Center Marriott. Registration was up 15% this year; snapped in the line in front of the registration desk at 9am was erstwhile Stereophile staffer Jonathan Scull (sensible suit, smart tie, and flashy glasses), these days a successful PR and marketing consultant.
According to Marjorie Stiefel, who with her husband Al slaves over the Rocky Mountain Audio Fest for months on end, this year's RMAF has 142 exhibit rooms, 29 more than last year. The show, has in fact, not only reached the hotel’s size limit—the DTC Marriott is Denver's third-largest—but also exceeded Marjorie's and Al’s energetic capacity. Fried to a crisp beyond the smile, the couple is considering hiring help for next year in order to meet increased demand from such major players as Linn, McIntosh, Esoteric, dCS, Kimber, Wilson, BAT, Gamut, Clearaudio, Edge, Ayre, Nordost...you name them.
Nelson Pass is up to good again. Following the wonderful sound of Ella and Billy I heard in the corridor, I discovered Nelson's prototype open-baffle speaker system. It sports both a Lowther PM6A full-range driver and a pair of SEAS W26 10" woofers. The 40"-high open baffle, which at this stage of the game is not intended to be a final design statement, has no side panels, only a central brace in the rear. The system was bi-amped, with the Lowther driver fed using a 60Hz, 6dB/octave high-pass filter feeding a First Watt F3 7Wpc JFET amplifier. The woofers were driven by a Pass Labs XA30.5 fed by a 12dB/octave active crossover. No equalization was employed. That the sound was so good was especially amazing, considering that the digital front end was pieced together at the last minute after the originally intended computer drive arrived minus its charger chord. I look forward to hearing the finished product.
Santy Oropel of Twin Audio Video Inc. of Loma Linda, CA was producing some very nice sound with Triode Corporation’s TRV-A88SE, a KT88-based, 12Wpc, single-ended integrated amplifier ($1800) and TRV-4SE Limited Special Edition tube preamplifier ($2750). Everything save the faceplate and casing is made in Japan.
I was utterly intrigued by the innovative speakers from Dr. Shelley Katz’s UK-based Podium Sound ($5995/pair). Katz produces panel loudspeakers that mechanically vibrate via electromagnetic drivers. Inherently free from phase error and less sensitive to placement than electrostats, they operate full-range without any filters.
John Atkinson and I have made an agreement. When John is not taking part in any of the eight "Demonstration of Live High-Resolution Recordings" seminars he has scheduled over the course of the Fest, he will cover the exhibits in the Marriott's Atrium rooms, and I will cover exhibits in the Tower. Of course, each of us is free to cross over to the other side if we're dying to hear something. But that's the plan.
I couldn't resist the wonderful sounds of Louis Prima coming from the Green Mountain Audio room. Paired with Jaton Corporation’s Operetta AP2140A 2-channel Distributor amplifier ($1000, 140Wpc into 4 ohms, 70Wpc into 8 ohms), whose "processing filter circle eliminates 99.99% of noise at maximum volume," the intriguing-looking Green Mountain Calypso loudspeaker ($10,000/pair for the next month or so before the price increases 10–15%) was producing the kind of extremely smooth sound that draws you into the music. The speaker measures 88–89dB sensitivity, and utilizes a simple, first-order crossover to achieve "perfect" time-coherence. The midrange and tweeter are also adjustable forward and back for optimal sound in the listening position. The entire system, including the speaker, was wired with Marigo wire. I constantly find that Green Mountain's innovative designs produce lovely sound. Expect a whole new line of smaller, less-expensive speakers to appear on the Green Mountain website in another month or so.
