John Atkinson was one busy camper at RMAF. In addition to blogging the show and moderating Saturday afternoon's information-packed, standing room only Computer Audio Panel, John presented four hour-long seminars entitled PC Audio—Squeezing the Music Till the Bits Squeak, playing all his music examples from his MacBook laptop via a Metric Halo FireWire interface. The setting was Evergreen E, the large, excellent-sounding exhibit (Sony and JBL speakers, Mark Levinson amplification, EMM Labs preamp and digital source components, Kimber kables) assembled by Ray Kimber of Kimber Kable.

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.

Both <A HREF="http://www.stereophile.com/artdudleylistening/1204listening/">Art Dudley</A> and Michael Fremer have praised Gingko Audio's isolation platforms in <I>Stereophile</I>'s pages, and at RMAF, the company was showing the benefit of its Cloud 10 platform on an Atmasphere tube power amplifier. Projected on the wall above Gingko's Vinh Vu (and onto his forehead!), real-time analysis showed the outputs of B&K accelerometers fastened to the stand the amp was sitting on and to the amplifier chassis, which was supoorted by a Cloud 10. There was indeed a dramatic reduction in the excitation of the amplifier compared with the stand&#151;especially at low frequencies.

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.

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.

Visiting the Soundsmith room is always a pleasure. Peter Ledermann's phono cartridges, preamps, and diminutive, how-can-such-a-little-box-produce-that-much-sound speakers always deliver superb sound.

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 25Hz&#150;40kHz, 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.
