To paraphrase Donald Rumsfeld, it is the "unknown unknowns" in audio that scare the pants off me at times. Synergistic's Ted Denney pulled me into his room. "Sit down. Listen to this."

I always make a point of seeking out a Wilson dem at Shows, and in the RMAF room run by Denver dealer Audio Unlimited, I encountered not one but two systems featuring Wilson speakers. The smaller system offered WATT/Puppy 8s driven by Balanced Audio Technology's VK53 CD player and $6000 VK55SE integrated amplifier—compared to its predecessor, this now uses 6BH30 input and driver tubes, sitting on tubed current sources—and sounded sweet indeed. But the real reason to visit this room was to hear the mighty MAXX2s driven by BAT's new Rex three-chassis ultimate preamp, VK600SE solid-state monoblocks and the new Paganini three-box SACD player—transport, clock, DAC—from English company dCS. BAT's Geoff Poor put on Frank Sinatra's Nelson Riddle-arranged "What's New," which Geoff feels is the singer's finest performance. Wow! Mr. Sinatra was there in the room with us.

One aspect of audio Shows that I love is the software pavilion, where audiophiles can browse new, old, are rare vinyl to their hearts' content. Acoustic Sounds’ Chad Kassem wanted to show me some of his new Analog Productions releases, but ended up telling me about his recent purchase of 30,000 sealed LPs—one and a half 53' trailer's worth—that had been in storage since 1981, the stash assembled by an eccentric collector long since passed away.

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.

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.

A definite eye-catcher, the $25,999/pair spherical Proclaim Audioworks DMT-100 speaker system features an external crossover that facilitates the ability to balance stereo output in difficult listening environments. (The crossover includes an L-pad bypass option to ensure "the cleanest possible signal path...for audio purists.") Each driver is independently mounted in a spherical enclosure cast from a proprietary high-density laminate. Fine-tunable for one's room, each driver can be adjusted up to 45° off-axis; they also afford up to 12" vertical and horizontal positioning flexibility for the tweeter and midrange modules. Daniel Herrington's babies, designed by ear, are so new that their sensitivity has yet to be measured.

In a room tuned with the amazing Acoustic System Acoustic Resonators to sound good with the glass window exposed, Darren and Bonnie Censullo of Avatar Acoustics displayed a system distinguished by the kind of openness and air that some people would kill for. Products included the Abbington Music Research AMR CD-77 and AMR AM-77 ($8500 each, both outfitted with NOS tubes), Acoustic System Tango Speaker ($13,500/pair), Current Cable Powercord and interconnects, and a host of Acoustic Resonators. If you look closely, you may see one of the diminutive resonators ($200–$2200) on the rear window. This is one system I hope to revisit if time allows. I’d love to hear some of these products in my own listening room, which is far bigger than the hotel suites into which most systems were shoeboxed.

We first encountered the South African Vivid speaker, designed by B&W alum Laurence Dickie, at a CES a couple of years ago and was impressed with their clarity, dynamic range capability, and freedom from coloration and distortion. For whatever reason, the brand failed to get a foothold in the US, but it was announced at RMAF that Vivid was now being distributed by On a Higher Note. I sat down in the sweet spot and after listening to a rather nice recording of Aaron Neville singing "Save the Last Dance for Me," Philip O'Hanlon put on a DVD-A he had burned on his PC using the $49 Cirlinca program and was playing back on a Weiss Jason transport and Medea DAC, which On A Higher Note is also now distributing. Now there was a familiar sound—it was the 24/88.2 master of my recording of the slow movement from the Mozart Clarinet Quintet, which I had completely forgotten sending Philip a few years back.

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.

As Jason said, I started my coverage of the much-expanded RMAF with the Atrium rooms, and at the corner of the ground-floor level, I encountered Gary Leonard Koh of Genesis Advanced Technologies. Gary brought me up to date on what has been happening with the Seattle company since parting ways with veteran speaker designer Arnie Nudell.

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.

The delightful Gilbert Yeung of Blue Circle, minus the Mickey Mouse ears and Snake Oil display I encountered at the last Show, has a thing for circles. I'm not complaining. After seeing boxes upon boxes upon boxes, encountering a surfeit of circles is super. (I have a feeling someone is going to rake me over the coals in the comments section for that one.)

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.

Toward the end of Day One, I encountered my Bay Area Audiophile Society buddy Jeff Wilson in the hallway. Jeff, a true music lover and long-time audiophile whose ears I trust, is about to open a showroom with Bob Kehn in Oakland, CA that will feature Magico, VAC, Silversmith, and other top-quality brands.

Undoubtedly contributing to the excellent sound I heard from the Vivid speakers in the previous story was this neat 30Wpc class-A integrated amplifier, the L-590A II ($9000) from legendary Japanese brand Luxman, shown here sitting on the top of the stack of Weiss gear. On A Higher Note is now distributing Luxman in the US.
