Much of Keith O. Johnson's invaluable presentation consisted of a series of graphs that demonstrated everything from jitter to the noise created by certain power cables. One of his many messages was, if folks think there are no differences between cables, I have the graphs to show otherwise. He also exhibited graphs that show how the quality of manufacture of CDs makes a huge difference in the ultimate analog signal. Want to see what a bad DAC or amplifier does, and compare it with a state-of-the-art unit? Keith can show you. Pictured is a tone-cluster wave he developed as a diagnostic tool that resembles music.
In my last blog report from T.H.E. Show in Las Vegas, I waxed ecstatic about the extraordinary, highly efficient, hand-made washi-paper Feastrex drivers distributed by Joe Cohen's Lotus Group of Northern California. The units are hand-crafted in Japan by Haruhiko Teramoto, who hand-rubs the frame, phase plug, and voice-coils of both his Feastrex D53 III 5" field-coil drivers ($39,000/pair) and D9e II 9" field-coil drivers ($31,500/pair) with traditional urushi lacquer.
After my first day of blogging, one dedicated Stereophile reader dropped John Atkinson a note to lament that I was mainly concentrating on large systems to the expense of smaller ones. Happily for all parties, one of the smaller exhibits he urged me to visitthe Feastrex roomsI had already checked out and have since blogged about.
A surprise outside the Hyatt as I went to get ready for my Sunday morning hi-rez audio dems was this SCCA Mazda race car. Sponsored by RMAF, Focal, Aesthetix, and Tara Labs, among others, driver Christine Jerritts had me enthralled telling me what it was like to take the infamous corkscrew turn at Laguna Seca Raceway. I could have lingered for a long time , but I had to get to work...
It takes people of vision to advance sound quality in an errorthank you, Mr. Freud, I mean erawhen record companies often seem set on anything but advancing the quality of music and musical reproduction. Hence, for his panel "Adventures in Digital Formats, Upsampling & Dithering," John Atkinson and RMAF's Kurt Bauer assembled an extraordinary panel.
Seriously, it's almost as if I haven't listened to any music at the Rocky Mountain Audio Fest. I just walk from room to room, running into people in the halls. These two weren't even exhibiting. They were simply here to have a little fun.
There's nothing like ending a day at RMAF with a reminder of what the real deal sounds like. If Ray Kimber had his marching band blasting their way around the lobby, the fabulous multi-feted, Grammy Award-winning recording engineer/producer Cookie Marenco gifted us with her renowned piano teacher, Art Lande tinkling the keys in the Marriott's Atrium on Saturday night.
One feature of this year's RMAF that has catapulted it into the major leagues of audio shows was the sheer number of well-attended workshops and panels scheduled at the Hyatt. Over the course of three days, one room featured "Let's Get Digital" with Robert Harley of The Absolute Sound, "Music Everywhere" by Steven R. Rochlin of EnjoytheMusic.com, "The New Music Label" by attorney Ned Hearn, "Adventures in Digital Formats, Unsampling & Dithering" with our own John Atkinson, "Digital Playback Equipment Design Considerations" with David Solomon of Signal Path International, and "Music Discovery" with consultant Sean Leonard. Many of these were panels, with a host of additional participants.
One of the joys of John Atkinson's RMAF panel session was discovering a remarkable unanimity of understanding and vision amongst a group of men who work in different countries on different areas of sound reproduction. Amidst scribbling seven pages of notes that barely scratch the surface of the knowledge and wisdom shared by panelists, I looked up to discover John and everyone having a ball as they spoke with one mind about the current state of the commercial recording industry, and the future of high resolution formats.
Physicist Jack Bybee of Bybee Technologies has now licensed his quantum purification nanocarbon technology to David Caplan's new company, Bybee Wire. Distributed by Laufer Teknik, the new Bybee Wire cables and power purifier include Bybee devices that clean up quantum mechanical noise at the sub-atomic level.
The room was standing-room only, with three rows of chairs, both side walls, and the back walls filled with folks eager to hear one of the dream systems assembled by Denver retailer Audio Unlimited. Where shall we begin: the dCS Scarlatti Stack which consists of the CD/SACD transport, DAC, master clock, and upsampler/digital-to-digital converter (by my math $81,000 total, and by anyone's math a fair hunk of change); the BAT REX linestage ($20,000), BAT VK-P10SE phono stage with new Super Pak Premiere ($16,000), BAT VK-600M SE monoblocks ($26,000); Running Springs Audio Dmitri Conditioner Premiere ($4,000); Hansen's new Audio Emperor loudspeakers ($60,000/pair); or the little bundle of TARA Omega Gold and 0.8 cables that together cost at $36,000 but probably far more? The take-no-prisoners sound was stunning. So stunning that some of the people were pinned to the back wall. Wow!
And here is Walter Swanbon of Fidelis AV, importer for Harbeth and Gradient loudspeakers. Here you can get a better sense of the size of the M40.1 loudspeakers. To Walter's left is the newest member of the Gradient family, the Laura ($3995/pair). Intended for use in conjunction with the Helsinki or as a stereo pair, the Laura employs a coaxial drive unit and is designed to be positioned in close proximity to the front wall of your listening room. It's pretty, too.
Hosted by Luxman, Synergistic Research, and Vivid Audio, the event was billed as "a private reception of fine music, conversation, and superb wine." Gus Gus played in the background, the room was filled with smiles, and, indeed, the conversation flowed as easily as the wine. While it was great to become reacquainted with some familiar faces, I also enjoyed the opportunity to make new connections.
