The Burning Amp Festival is almost upon us. The day-long DIY (do-it-yourself) love fest, held within yards of the San Francisco Bay, attracts a good 150 DIYers from around the world who engage in the annual ritual of demming their homemade gear for other avid audio enthusiasts.
The sixth annual Rocky Mountain Audio Fest had already closed when I finally had the time to stop by Reference Recordings’ booth to check out their latest mouth-watering HRx high-resolution master WAV file DVD-Rs. There I encountered Demian Martin, who, together with Ray Burnham, has produced the Auraliti (pronounced Aurality) disc player ($800).
As the sixth annual Rocky Mountain Audio Fest draws to a close at the Denver Marriott Tech Center, what is now the largest annual audio show in the USA could boast an attendance of 3700, 200 more than last year. Prominent among attendees from 49 states and overseas was a notable increase in the number of under-40 attendees. No doubt they were drawn by the rise of audiophile computer-audio playback, the resurgence of vinyl, and the large exhibit hall populated by the Head-Fi headphone community. The younger attendees included an influx of students, who responded to RMAF’s concentrated outreach to local colleges.
At least two people I know came up to me in the hallways of the Marriott to urge me to check out Intuitive Audio's new Gamma Summit speakers ($10,000/pair). As soon as I walked into the room, the fabulous bass on Patricia Barber's rendition of "Keep on Using Me Until You Use Me Up"I'm guessing at the titletold me why. The system's riveting presentation also featured the kind of musical highlights for days that audiophiles love. Next I heard the same Mahler Symphony 2 recording I've been playing a lot at RMAF 2009. The speakers did an extremely fine job of controlling and highlighting the bass line, and also sounded very vibrant on top. Congratulations to designer Dale Pitcher for a job well done.
I first discovered the Eficion F300 loudspeaker ($14,800/pair) at RMAF 2008, where its full-range sound deeply impressed for the price. Since then, the speaker has undergone numerous refinements. Split into two separate compartments, separated by Stillpoints, this is a 3-way 4-driver vented box with a frequency response of 25Hz40kHz, 89dB sensitivity, and 8 ohms impedance, with a minimum of 6.4 ohms. The front tweeter is an Air Motion Transformer, its rear-firing super tweeter a Heil ESS aluminum ribbon, and its 7" midrange and 12" woofer both from Aurum Cantus. All this has produced a more controlled and detailed sound. Other refinements are identified on the Eficion website.
After several years without distribution in the US, Peder Beckman of Norway's Electrocompaniet (kneeling on the left, next to company head Mikal Dreggevik) has quickly established a revitalized US dealer network that should number a good 10 by CES 2010. Without a long-standing reputation for affordable excellence, this would have been next to impossible to achieve in the current climate.
Having just heard a Bay Area Audiophile Society (BAAS) demo of the PS Audio Perfect Wave Transport ($2999), Perfect Wave DAC ($2999), and Power Plant Premier ($2199), all hosted by the ever-engaging Paul McGowan, I was very eager to hear PS Audio's front end powered by an early prototype of PS Audio's forthcoming class-D Perfect Wave amplifier. Using Focus Audio Master 2.5 speakers ($20,000/pair), two MartinLogan Descent subs, and a complement of Perfect Wave AC12 power cables ($699/meter) and older PS Audio speaker cables not currently on the market, the system delivered the kind of clean, impressively full range sound that has made PS Audio a legend in the industry.
Bless Ray Kimber's heart. For at least the last three years, Kimber Kable has transported live musicians to RMAF so that we could always have a fresh, live reference in our heads as we traipsed room-to-room listening to canned performances.
